Hi Yogita.

Can you deny that any macros are processed when closing the Excel file?

Betreff: RE: Reading value from formula cell

I understand that POI doesn't evaluate the formula and Excel does it.
This is what I am doing:

-I am creating a spreadsheet.
-Writing a formula cell.
-Saving the file to disk
- then opening it manually. I can see the correct results in the formula
cell. I close it.
- then I open the same file in java program using poi
- read the formula cell using getNumericCellValue
It returns me the value 0.0.
Should it not retun me the calculated value ?
Is it a bug in POI ?
Is there any alternate solution to do this ?

We are sort of stuck on this. Would appriciate any quick response.

Thanks,
Yogita.

Hi Tony,

Thanks for your reply.
I am creating the spread sheet and creating a cell as stated in previous
message.
As a second step( after creating the spread sheet and saving in excel
file) I am opening the excel file and re-reading the formula cell. This
read is always returning me 0.0.
What could be the problem with this ?
Is teher any alternate way to read value from formula cell.

Thanks,
Yogita.

POI does not evaluate formulas.  Excel does that.

POI simply puts the forumla in the cell.   In order to get a value, you
would
have to create the spreadsheet, open it in excel, and then re-read it
with
POI.

This was discussed in detail less than two weeks ago on the list.
