I use Aspose.Cells to convert Excel files to HTML.
Conversion of some documents takes a lot of time.
I investigated such files and found that Aspose.Cells generats many empty Cells.
empty_cells.zip (2.3 MB)
image.png (1.9 KB)
I found an option MergeEmptyTdForcely. Setting the MergeEmptyTdForcely parameter to true leads to faster conversion.
However, some other Excel files are converted with loss of content.broken_with_enabled_MergeEmptyTdForcely.zip (3.1 MB) - second tab.
How to improve performance correctly without losing content?
