I'm pretty new to use POI. I can read values from Excel file by reading it. But during the read, it seems I cannot change Excel cell values.
The above code won't really change the value to "TEST" for that cell after the program is finished.
If using FileOutStream with an output file name, I think it's just gonna overwrite the existing file, or create a new file.
How can I change the values in an existing file? Thanks.
