InDesign Excel empty cells

• POI cellIterator ignores empty cells.  How to catch?

  For the experienced:
  
  I have never dealt with Microsoft Excel files using java and have just started using the POI library to read data from Excel files. In the .xls file I get, there are cells that are found to be empty, although they aren't supposed to. So I have to catch these empty cells and treat them accordingly.
  
  To learn how to catch these empty cells, I created a spreadsheet of Excel a line test and wrote the following class to try to catch empty cells.
  
  The one line in the sheet has 5 columns as shown below. I entered < tt > ' 0934 < /tt > in column D with an apostrophe leader to make sure that it is stored as text.
  

  A     B        C      D     E
  ----  -------  -----  ----  ---------
  John  (BLANK)  123.4  0923  4/21/2011

  And here is the test class to examine these cells. Sorry that it is quick and dirty for the test and I don't use a try/catch and I simply leave the date column be printed as a number:

  public class ExcelTest {
      public static void main(String[] args) throws IOException {
          // The one-row test file:
          String inputFilename = "c:\\test_data\\test_sheet.xls";
          FileInputStream fis = new FileInputStream(inputFilename);
  
          HSSFWorkbook workbook = new HSSFWorkbook(fis);
          HSSFSheet worksheet = workbook.getSheetAt(0);
  
          // Get the one row
          HSSFRow theRow = worksheet.getRow(0);
          // and create an iterator
          Iterator cells = theRow.cellIterator();
  
          int columnNo = 0;
          
          // Go through the cells in the row:
          while (cells.hasNext()) {
              // Get the next cell:
              HSSFCell cell = (HSSFCell)cells.next();
              
              int cellType = cell.getCellType();
              String cellTypeDesc = null;
              String cellValue = null;
              
              switch (cellType) {
              case 0:
                  cellTypeDesc = "NUMERIC";
                  Double doubleValue = cell.getNumericCellValue();
                  cellValue = doubleValue.toString();
                  break;
              case 1:
                  cellTypeDesc = "STRING";
                  cellValue = cell.getStringCellValue();
                  break;
              case 2:
                  cellTypeDesc = "FORMULA";
                  cellValue = cell.getCellFormula();
                  break;
              case 3:
                  cellTypeDesc = "BLANK";
                  cellValue = "BLANK";
                  break;
              case 4:
                  cellTypeDesc = "BOOLEAN";
                  boolean booleanValue = cell.getBooleanCellValue();
                  cellValue = ""+booleanValue;
                  break;
              case 5:
                  cellTypeDesc = "ERROR";
                  byte byteValue = cell.getErrorCellValue();
                  cellValue = ""+byteValue;
                  break;
              }
              System.out.println("Column " + ++columnNo + " has value " + cellValue + " of type " + cellTypeDesc);
          }
      }
  }

  I expect that the class could give me some clues on the empty cell. But it turns out that the program returned only 4 columns, and the empty cell is omitted altogether as there were not any. That's what the program returned:
  

  Column 1 has value John of type STRING
  Column 2 has value 123.4 of type NUMERIC
  Column 3 has value 0923 of type STRING
  Column 4 has value 40654.0 of type NUMERIC

  Is it possible to catch empty cells?
  
  Thank you very much for help!

  Looking through the javadocs POI, because cellIterator() does not return empty cells, you can use the getCellNum() method to determine the position of the cell in the row. You should be able to use it to determine when a cell is ignored because being blank.

• Find the first empty cell

  OK so I use numbers to design a "schedule" for lack of a better word for a flight instructor course. On the summary page, I need to be able to identify the next sequence of flight for each student. I have a sheet that contains all flights that each student must perform and the date which they filled. So what I need on the summary page is someway to watch flight logs and determine what the next flight is to find the first empty cell under each name of students. I have no idea how to go about that though, so if you have any ideas I would be grateful

  Hello j,

  Here are two possibilities, both illustrate below. They are independent of each other and can be used alone or together.

  If students all sequences in chronological order, and the dates in columns are values of Date and real time, you should be able to locate the first empty line using MATCH and MAX.

  Because all dates entered will be 'today' or 'before today', a conditional highlighting rule could be used to color the background of the cell to a cell where a date has been entered.

  

  Table 1 gives the master record. Table 2 shows the following sequence for the student and the line of table 1, which the sequence is listed.

  Two formulas are used:

  Table 2::B3 and filled with right: = MATCH (MAX (table 1: B), Table 1: B, 0) + 1

  Table 2::B2 and filled with right: = OFFSET (table 1: $A$ 1, B3-1, 0)

  This method is based on the sequences being completed in the order listed, as it seems the most recent (that is to say date the "bigger").

  The rule of conditional formatting applied to all cells in columns B, C and D of table 1 fills every cell that contains a date before the next day with yellow, giving a visual indication of where all the next vacant cell.

  This indicator is independent of the order of the sequences, because it depends on only that there is a date or before 'today' in each cell to be highlighted.

• How to add the first non-empty cell (text) in a row

  I have a table of several lines of contact details (phone, cell phone, fax and email) of people. I'm using these data to a data merge using an exported csv file and must include only the text (phone numbers and/or email) that is not empty.

  Column A - phone

  Column B - cell phone

  Column C - Fax

  Column D - Email

  Column E - first non-empty cell (between A1:D:1, A2:D:2, A3:D3, etc.)

  Column F - second non-empty cell (between A1:D:1, A2:D:2, A3:D3, etc.)

  Column G - third non-empty cell (between A1:D:1, A2:D:2, A3:D3, etc.)

  I tried to use some varieties of INDEX MATCH, but I don't do it just because its does not work properly.

  Any help would be appreciated. Thank you!

  

  You can try something like this:

  

  E2 = IF (ISBLANK (A2), "", MAX($D2:D2) + 1).

  This is a shortcut for, select cell E2, and type (or copy and paste it here) the formula:

  = IF (ISBLANK (A2), "", MAX($D2:D2) + 1).

  Select cell E2, copy

  Select cells E2 through H2, dough

  I2 = SIERREUR (OFFSET ($A2, 0, IFERROR (MATCH (COLUMN (−8), $E2: $H2, 0), ' ') −1), ' ')

  Select the cell I2, copy

  Select cells I2 thru K2, dough

  Select cells E2 K2 thru copy

  Select cells E2 at the end of the K column, paste

  You can hide the columns e to H what you like

• the search for empty cells by using the query designer

  Hello

  I'm trying to exclude empty cells in a field (by using the Query Builder), and I did:

  xDocumentSource < match > "CDL".

  < AND >

  < NOT > (xRelatedMsgid < match > "" "")

  but it does not work. I tried "NULL", but it does not work either. Could someone tell me how to do it (or where I can find examples of queries).

• Enter data into the empty cell inserts the invalid main character

  When I enter data in an empty cell, for example 1 in a column, and then click validation I get the error ORA-01722: invalid number. Although I do not see the character in front of the 1 I use RIGHT twice after reaching HOME in this cell to get the cursor to the right of the 1, if a character appeared in front of the 1. Hit the BACKSPACE deletes the invisible character, and now I can commit the data entered.
  
  The same thing seems to happen when you remove a date using backspace in a date column. The use of return back once led to an error "ORA-01858: a non-digit character was found here where was waiting for a digital". I have to use the BACKSPACE again to get the empty cell.
  And the same thing happens in a varchar column too, although sometimes when he gets that space seems to be inserted in front of the text I entered, but this space is visible only when the cursor is not in the cell.

  Can you send an example idml or inx?

  If not maybe you can try something like this:

  var aDoc = app.documents[0];
  var allTables = aDoc.stories.everyItem().tables.everyItem().getElements(); 
  
  app.findTextPreferences = app.changeTextPreferences = null; 
  
  app.findTextPreferences.findWhat = "";
  app.changeTextPreferences.changeTo = "";
  aDoc.stories.everyItem().tables.everyItem().changeText();
  app.findTextPreferences = app.changeTextPreferences = null;
  alert("done");

• Using find/replace to find empty cells in a table

  I'm working on several catalogues pages where we apply styles of our catalogues. The find/replace feature really helped do, but I can't seem to find a way to find an empty cell in a table to add a style to only the cells that are empty. If someone knows a way to do this, saving me a bunch of times and I would be very grateful!

• Member of dimension values does not (empty cells just)

  Hello
  
  I have a dimension of the Organization (company > Business Unit > Department > account) and one made (in Dollars) on my test repository. When I add my fact and any level of the dimension of a report of responses I see for example two empty cells for each Member to the 'Business' level and the result of my calculation. I tried several ways to address this issue of aggregating my data to compress all of the dimension in a single table and still have had no success. I also turned on logging and discovered that the generated SQL physical layer returns the correct values when I run in my query tool.
  
  Anyone knows similar behavior? I don't know if I skipped a step on my modeling or it is a bug in my installation of OBIEE
  
  Thank you very much!!

  Hello Ignacio,

  Did you check the length of your columns in the physical layer?

• IF statement back to '0' on empty cells

  How can I get an IF statement to display a cell instead of '0' when it encounters a blank cell in the formula?

  I want to empty E2 is B2 is blank

  In cell E2

  = IF($a2="Media",B,"")

  	A	B	C	D	E	F	G

• Look for an empty cell in the report

  I have a report that displays true or false in the rows for a number of car models which are the columns.

  I have the case statement below the installer in the section formula column in one of my columns.  It sort of works, but if "FT_AUTOS". "' productionEnded ' is nothing (i.e. no returns nothing, not even NULL), then it will just show a blank cell.  Is it possible to include "empty" so that it also presents itself as being incomplete?

  case

  What SUM (case when "FT_AUTOS".) "productionEnded" (IS NOT NULL then 1 else 0 end) > 0 "

  then ' < div title = "True" style = "background: #00ff00;" "text-align: Center" > ' | "Real ' | ' < / div >"

  else ' < div title = "False" style = "background: #ff0000;" "text-align: Center" > ' | "False' |' < / div >"

  end

  Thank you

  length ("FT_AUTOS". "productionEnded") "

  you could talk about NULL or "or ' ' etc.

  forget your report for a while and it just pull this column with top expression and then run it, sort asc

  Then look at the values and then sort DESC

• Scan of the columns in table for empty cells

  I have prepared a form that will do the following (Please bear with me for the description):

  The form opens with a table of 10 rows.  The user must enter sides (from 0 to 10) in one of the columns in the table.  Once the user enters all the ratings of ten, he or she must then click a button to turn on the rest of the form (which is hidden).  What I'm trying to do is, after the button is clicked, scan the table to ensure that the entire column was filled with a number.  If the column was made, then a second page.  If a cell in the column was left in white, then I want a prompt to appear and indicate to the user which cell is empty.  I was able to run by using the following code:

  This code is under the event 'click '.

  If (decisionMatrix.dMTable.Row4.rating.rawValue is nothing)
  {
  Poster a warning prompt that indicates the form is incomplete

  xfa.host.messageBox ("incomplete form.  Please fill in the background. ","warning ", 3);
  }
  on the other
  {
  Allow the user to save the current state of the form and activate the second part of the form.
  app.execMenuItem ("SaveAs");
  }

  The problem with the above method is that it checks only the Row4 cell.  I have to add more code for the other 9 rows in the table and for each message box, indicating to the user which field to fill.  Is there a better way to do it?  A switch-case perhaps statement?

  I have also considered the column full analysis at a time and just using a message box general for the table, using the following code:

  If (decisionMatrix.dMTable.Row [*].rating.rawValue is nothing)

  {
  Poster a warning prompt that indicates the form is incomplete

  xfa.host.messageBox ("incomplete form.  Please fill all of the scoring. ","warning ", 3);
  }

  ...

  But it doesn't seem to work.  Any help is appreciated.  Thank you.

  The seal contains a table with 10 rows and 3 columns (a_, b_ and c_). The calls button 'Continue' by clicking on the click event, which runs through the table looking for NULL values in each column per row. The "ratingMissing" flag controls the visibility of the page 2.

  Form1.Page1.Subform1.continueBtn::click - (JavaScript, client)

  var ratingMissing = false;

  for (var i = 0; i)< 10;="" i++)="">

  var line = i + 1;

  If (xfa.resolveNode("form1.page1.subform1.table.row["_+_i_+_"].a_").rawValue == null) {}

  xfa.host.messageBox ("A is missing in row"+ row);

  ratingMissing = true;

  }

  If (xfa.resolveNode("form1.page1.subform1.table.row["_+_i_+_"].b_").rawValue == null) {}

  xfa.host.messageBox ("B is not in the line" + row);

  ratingMissing = true;

  }

  If (xfa.resolveNode("form1.page1.subform1.table.row["_+_i_+_"].c_").rawValue == null) {}

  xfa.host.messageBox ("C is missing in the row" + row);

  ratingMissing = true;

  }

  }

  If (ratingMissing == false) {}

  Form1.Page2.presence = "visible";

  }

  else {}

  Form1.Page2.presence = 'hidden ';

  }
