This is probably too simplistic but try to get the value of the Excel cells as String by getStringCellValue(). But this will probably throw a runtime exception about the format of the cell data. I also encountered similar problems with my workbooks. After working with work arounds for a while, I got tired of it. So, I wrote a Visual Basic sub (a glorified macro essentially) which would take the original workbook and paste the relevant data into a new workbook. Basic data pre-processing. That's where I got rid of the annoying stuff like $ and ',' symbols; percentage conversions from e.g. 60% to .6 etc. A favorable side effect was reduction in the file size of the workbooks I had to read as the new workbooks were only about 20KB as opposed to the 830KB filesize of the original workbooks. Huge performance gains there.
This is something you might want to look into if nothing else works.

My spreadsheets can contain a column with the following codes shown in the table. The formatting of the cells is set up as Custom 0000000 0003322 0047345 7088449 7145456 2380398 0234400 I do know that the column should be set to Text, since that is what it contains, these are not numbers but codes. However I have no control over this since I have not created the data. Whenever I read the values out of the cells I get the following doubles. 3322.0 47345.0 7088449.0 7145456.0 2380398.0 234400.0 POI is reading the correct value from the sheet, the values read are the same as the ones shown in the Formula bar whenever the cell is selected. The Excel application is taking the Formatting preference and displaying the leading zeros to the user. How can I get POI to read the values that are shown in the table after the formatting has been applied. I want the String 0003322 for the first cell for example. I'm sure that this is not the first time this problem came up, I've searched the mailing list archive but only seen people trying to preserve the leading zero when writing Excel sheets. thanks for your time, Martin. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/
