.csv file BLOB conversion

• Conversion of hundreds of data in CSV files. Script on command prompt?

  Hi, so I think I have a unique problem with an easy solution. I have more than 1400 files which are actually (roughly acsii) RAW data files that I need to parse CSV files converted. They are all in the same folder, and I know there are scripts there to take all the files in the folder and the list of people in the CSV format. I just want to convert all the files in the CSV file. I could use Excel and manually convert all 1400 of them, but there must be a better way. Also, it would be great if everything was annexed to 1 VERY large CSV file.

  I'm relatively new to the windows command prompt window, so any help would be greatly appreciated.

  Thank you!!

  Check this: copy command to allow adding files: https://www.youtube.com/watch?v=MX2SXdR9yfw

  You can use it to combine all the files, then open them only once, and convert the whole thing to a CSV file in a single step.

• Conversion of out-line of output to a. CSV file

  Hi all

  I was wondering if it would be possible to convert the output of the out-file cmdlet to a .csv file.  When I use out-file it creates a text file that puts each item on its own line.

  For example, the text file would be:

  Server2

  Server3

  Server4

  I would like to convert this .txt file to a .csv file, which would be:

  Server2, Server 3, Server 4, etc.

  I tried to use the Export-csv cmdlet instead of the out-file cmdlet, but I can't seem to make it work, so instead I was wondering if it would be possible to convert the text using a pre-made PowerCLI command or some type of line of the script to remove and replace characters and delimiters.

  Thank you very much for any help or assistance that anyone can give.

  Best

  Oops, my mistake.

  See if it works for you

• Import CSV file and the conversion of an array

  Hi all

  I'm working on a site that is to import a CSV (comma separated values) published via actionscript 3.0 URLloader().  Now I just try to get actionscript to successfully enter the data imported from the CSV file as a table, then the CSV file has 1 single cell that contains "athleticMaroon, charcoal, colonialBlue, kellyGreen, fullColor".

  Here is the code I use:

  create table

  var shirtLiveIntense_btn_Colors:Array = new Array();

  run the import from CSV data

  URLLoaderCSV();

  shirtLiveIntense_btn.addEventListener (MouseEvent.CLICK, selectingLogo);

  function selectingLogo(e:MouseEvent):void {}

  trace ("current logo');

  var colorButtons:Array = this [e.currentTarget.name + "_Colors"];

  for (var i: uint = 0; i < colorButtons.length; i ++) {}

  .Ivar colorButtons [i] = i;

  colorButtons [i] .addEventListener (MouseEvent.CLICK, shirtColorOption);

  }

  }

  CSV data import function

  function URLLoaderCSV() {}

  var loader: URLLoader = new URLLoader();

  configureListeners (loader);

  var request: URLRequest = new URLRequest ("https://docs.google.com/spreadsheet/pub?hl=en_US & hl = en_US & key = 0AlJnOKOffTSxdFk0RVlEUTVHeF9 DMHZfZ0JzSkJjZFE & single = true & gid = 1 & output = csv");

  try {}

  Loader.Load (request);

  } catch (error: Error) {}

  trace ("unable to load requested document.");

  }

  }

  function configureListeners(dispatcher:IEventDispatcher):void {}

  dispatcher.addEventListener (Event.COMPLETE, completeHandler);

  dispatcher.addEventListener (Event.OPEN, openHandler);

  dispatcher.addEventListener (ProgressEvent.PROGRESS, progressHandler);

  dispatcher.addEventListener (SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);

  dispatcher.addEventListener (HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);

  dispatcher.addEventListener (IOErrorEvent.IO_ERROR, ioErrorHandler);

  }

  function completeHandler(event:Event):void {}

  var loader: URLLoader = URLLoader (event.target);

  trace ("completeHandler:" + loader.data);

  shirtLiveIntense_btn_Colors.push (loader.data);

  }

  function openHandler(event:Event):void {}

  trace ("openHandler:" + event);

  }

  function progressHandler(event:ProgressEvent):void {}

  trace ("progressHandler loaded:" + event.bytesLoaded + "total:" + event.bytesTotal);

  }

  function securityErrorHandler(event:SecurityErrorEvent):void {}

  trace ("securityErrorHandler:" + event);

  }

  function httpStatusHandler(event:HTTPStatusEvent):void {}

  trace ("httpStatusHandler:" + event);

  }

  function ioErrorHandler(event:IOErrorEvent):void {}

  trace ("ioErrorHandler:" + event);

  }

  Here is the result:

  openHandler: [event type = "open" bubbles = false cancelable = false eventPhase = 2]

  progressHandler loaded: 57 total: 0

  httpStatusHandler: [HTTPStatusEvent type = "httpStatus" bubbles = false cancelable = false eventPhase = 2 status = 200]

  completeHandler: athleticMaroon, colonialBlue, kellyGreen, charcoal, fullColor

  chosen logo

  ReferenceError: Error #1056: cannot create ivar String property.

  at main_fla::MainTimeline/selectingLogo()

  Review of results of release, I see it's clearly to load the data from the CSV file correctly, but what I think it does is important data as a single string, aka 'athleticMaroon, charcoal, colonialBlue, kellyGreen, fullColor' and push for shirtLiveIntense_btn_Colors:Array = new Array().  But, as I see the error selectingLogo(e:MouseEvent) service cannot treat the table because it contains a string of.

  If I switch to shirtLiveIntense_btn_Colors.push (loader.data); with shirtLiveIntense_btn_Colors.push (charcoal, colonialBlue, kellyGreen, athleticMaroon, fullColor); everything works like a charm, but I need the table to assign dynamic in the CSV file data

  Can anyone help to get imported CSV data to strings pushed a table accessible?

  Thank you!
  

  
  

  It is an error caused by:

  var colorButtons:Array = this [e.currentTarget.name + "_Colors"];

  for (var i: uint = 0; i

  .Ivar colorButtons [i] = i;

  colorButtons [i] .addEventListener (MouseEvent.CLICK, shirtColorOption);

  }

  your table is an array of strings.  If you try to force these strings into objects on the timeline that contains your code, use array notation:

  var colorButtons:Array = this [e.currentTarget.name + "_Colors"];

  for (var i: uint = 0; i

  This .ivar [colorButtons [i]] = i;

  This [colorButtons [i]] .addEventListener (MouseEvent.CLICK, shirtColorOption);

  }

• cannot paste copied from CSV files online entered into the Excel worksheet (chatted with Cedric_L on 03/05/10 at approximately 2.30 CST but I got disconnected. not got an answer...)

  Here is the transcript of a chat with Firefox community member zzxcon may 3/10

  Now you are chatting with Firefox community member Cedric_L
  Cedric_L: Hello
  Cedric_L: what happens when you try to download a .csv file?
  Seegal: Hello
  Seegal: it is not copy
  Cedric_L: how you try to copy?
  Seegal: pls bear with me, I'm a slow typist. Just copy the selected text
  Biolizard joined the conversation.
  Cedric_L: ok - you choose what text?
  Seegal: I reconcile my checkbook (worksheet in this way). I copy my bank acc online items and paste it in the worksheet
  Seegal: I use Firefox 2.0.0.19. Have no problem to do so.
  Cedric_L: what version of Mac OS X?
  Seegal: in the new version nothing happens when trying to paste - just doesn't add up
  Cedric_L: Firefox 2.0.0.x is no longer supported and has not been supported by more than a year
  Cedric_L: paste into Excel from Firefox?
  Seegal: Sorry, I'm early... 2.0.0.19
  Seegal: Yes. I opened my bank acc in Firefox
  Cedric_L: what version of Excel?
  Cedric_L: it would really help if you could tell me step by step what you do.
  Seegal: first re: your previous question: is OS 10.4.11
  Seegal: on Excell: it' ACE 2004 version - the lasat one product for Macs. The specific version is 11.3.7
  Seegal: so I opened my ACC. to bank online in Firfox (my main browser). I copy the last entry in the account and paste in my Excel spreadsheet.
  Cedric_L: so, you copy directly from the web page without having to download a CSV file?
  Seegal: what do you mean by CSV file download? I could export to the https://chat-support.mozilla.com:9091/webchat/getimage? image = sendmessage & workgroup=support%40workgroup.chat-support.mozilla.comFirefox to the CSV file, but the other way around?
  Cedric_L: you copy your bank statement directly from the web site to Excel by using the Clipboard?
  Seegal: so do not use the Clipboard. It is a mac. There is no need to do so. In the PC, it would be Yes.
  Cedric_L: I need to know the exact steps that you deliver to bring in excel
  Cedric_L: and I need to know what exactly goes wrong in the latest version of Firefox.
  Seegal: you have a mac it with Firefox and Excel? It is very easy to reproduce. Imagine you open access to online banking, select a few entries, click on 'copy', to make your already open Excel worksheet and click "Paste". That's all!
  Cedric_L: when this happens, do you have cryptic code pasted into Excel?
  Seegal: as I said before: in all newer versions starting with 3.0 when I go to Excel to 'stick' of my bank acc, nothing happens. It does not stick. No, I don't get a cryptic code pasted, just NOTHING.

  Cedric_L: what happens if you paste into MS Word instead?
  Seegal: haven't tried, most likely the formatting would be lost. Tried with an another el Exc spreadsheet-it lost all the formatting and pasted as continuous text.

  This has happened

  Each time Firefox opened

  Is copy of the cat above. THIS MAC OS X. In the older versions before 3.0 I could copy the CSV file on the site Web Ibank VAC) and paste it directly to my spreadheet Excel reconciling my account.

  There is a known issue with Mac Office versions prior to 2007 version that results in release of Clipboard does not correctly supported. Firefox 3.0, being a more recent application, using the new format for the HTML Clipboard data. Unfortunately, Office 2004 and Office X do not support this.

  If you upgrade to MS Office 2007, it should work as expected.

• How to create a header in csv file

  I m still beginner in Labview, I'm just learning it this week...

  I want to do a data conversion for temperature probe...

  I m having trouble creating a header in the csv file, can anyone help me?

  I am also attaching my csv file, what I wanted to do like this:

  DT (ms)	channel 0	channel 1	Channel 2
  0.1	1	2	3
  0.2	4	5	6
  0.3	7	8	9
  0.4	10	11	12

  I also want to know how to make time to count 0 not real time...

  Citras wrote:

  I have to solve the problem, it s quite confusing, I have to use; instead of \t in the separator.

  What is so confusing to this topic?  You have chosen to use the semicolon, so you must explicitly specify the VI to use instead of the default of a tab.

  When I start the program, can I do the dt (ms) count of 0? What I can do is to use the Date/Time Format string, I want Don t the time based on real time count

  You can subtract the current time of the time at the beginning of the program. Use the time to get based on seconds outside of the loop let you time initially and then use it inside to get the current time. Subtract. Note that your loop is clocked by the software, so you won't get the same amount of delta.

  Also: do not hard code paths in the code. What do you think will happen if someone tried to run your VI on a XP machine? This will not work because of the path of the file. Use a control with a default value defined for it.

• LabVIEW csv file reading does not correctly.

  I try to use the spreadsheet read vi file as follows the attached csv.

  He did some things wrong:

  (1) the first cell in the resulting table has ÿþ attached to the front of it, it looks like labview is striking some special characters, it should not? (Notepad, notepad ++ and excel can open all the file with no problem and no show ÿþ or something like that).

  (2) it is abuse characters from end of LIFE as two line breaks, resulting in empty rows between each row of data. (Looking at the csv file in notepad ++ confirms that the lines are completed with a CR and LF (same as EOL).)

  (3) I read in sub form of string, because one of the columns is nonnumeric, but then I remove this column of and try to convert the remaining string table in a digital picture (failure). It also fails if I shoot an individual element of the array and try to convert it to a number (in either case, using the string fract/exp number), below, I have an example of attempted to read from the 2nd column of the 1st row (index: 0.1) which is being shaped as a string: "1.37238168716431" and conversion which gives 0 as you can see in the snapshot of the façade into a number.

  

  

  
  

• list box given to the .csv file using write on the worksheet File.vi

  Hi, I use the write on the worksheet File.vi to write data multicolumn ListBox to the .csv file. If I do record from Excel, the pop-up window shows as an attachment. And data listbox are too different.  I want the data displayed in the first line not the second row (third photo).

  Thank you for your help.

  Before making your Save As in Excel, change the cell formatting of number. This should avoid the scientific notation conversion before you re-register.

  Or just use Notepad to display the file instead of Excel.

• How to download the Csv file with column headers

  Hi all

  This is pavan, using Apex version 4.2.3

  
  

  I am trying to download the csv file I followed this link , and I'm able to download excel with headers, when I try to download with headers of this error "'ORA-01858: a non-digit character was found here where was waiting for a digital" I searched in google but could not find the right solution, "

  
  

  can anyone help on this please.

  Thanks in advance,

  
  

  Kind regards

  Pavan

  This article is 6 years old.

  You should study the solutions that are available for APEX 4.2: data loader or the 'Excel2Collection' plugin (which also manages the CSV files).

  Data Loader

  It is a wizard that generates an Assistant for your application.

  Excel2Collection

  You will use the Excel2Collection (in a single process) to convert the BLOB in a Collection

  Then, in a 2nd address), you just do a "INSERT...". SELECT statement.  Add ' where seq_id > 1 "for files with a header.

  MK

  PS - Use the "EXECUTE IMMEDIATE" article is not necessary.

  The order of the parameters for the parse_file in the specification and body must match. In your case, it stopped the p_separator parameter (before nom_table_p in spec, but otherway around body) which is the origin of the problem of compiling again.

• How to navigate through the CSV file by row and pass it by MFL

  I have a CSV file that got no. n. records with the new line ("N") that separates each record of the
  
  Each record is of about 10 fields or more delimited by ' |'
  
  for example.
  
  11111. "20090316152" | " » 0"| » 0"| » 0"| » 0"| » 0"| "1-7DT-439" | " » "||" N ".
  
  22222 | "20090216152" | " » 1"| » 0"| » 0"| » 0"| » 0"| "1-7DDI-439" | " » "||" N ".
  
  33333 | "20090316352" | " » 6"| » 0"| » 0"| » 0"| » 0"| "1-5KK-439" | " » "||" N ".
  
  The requirement is to read the file using OSB - file adapter and move all records to the MFL for the conversion of XML
  
  Thank you
  Danny

  What happens when you pass all $body as it is the transformation of MFL?

  As mentioned, this disrupts the question, because a possible answer was published in the OTHER thread... Check your server logs, you probably delay... Preliminary discussions with a similar problem:

  Take a look at the httpd.conf file (or get your system administrator to look at it) and see what's on the value of TimeOut. You may need to increase in order to export large tables by APEX.
