Problem:
|
| 9 |
An issue came up with thousands of Excel files where they needed to be tiffed but because they had
|
| 10 |
millions of rows of empty but not technically empty data, they would tiff out in the millions of pages.
|
| 11 |
Since there was formatting on those rows, LAW wouldnt remove the empty pages. Imaging in Relativity
|
| 12 |
also didnt work, since it would just error out.
|
| 13 |
|
| 14 |
Solution: This program will take a directory of Excel files, open them, using COM, and do the following, for every
|
| 15 |
sheet in the document:
|
| 16 |
* Unhide all rows and columns
|
| 17 |
* Determin the largest sheet area both for rows and columns
|
| 18 |
* Hide these "empty" rows.
|
| 19 |
* Save as a new version of the file.
