I am experiencing a strange issue when I convert certain spreadsheets to PDF, merge them into a single PDF and then do a Save As in any PDF authoring software such as Acrobat Pro. What is happening is that the cell values from page 20 (the start of the second spreadsheet) and on are getting updated with random values.
The test files are attached and here is my scenario:
1. I convert the attached spreadsheets to PDF using Aspose.Cells.
2, I then merged the 3 PDFs into a single PDF using Aspose.Pdf.Kit.
3. I can open the merged_orig.pdf file and the information displays correctly in Reader but if I open the merged_orig.pdf in Acrobat Professional and perform a Save As, the cells starting from page 20 and on get updated to random values (see merged_saveas.pdf).
I tried another test by merging the 3 PDF files after I converted them to PDF using Office 2007 (instead of Aspose.Cells) and I didnt have the problem, everything displayed correctly even when doing a SaveAs. I dont beleieve there are any formulas, etc. in any of the 3 spreadsheets, just values in cells.
Please help as this is a production system that has been using Aspose for over a year now and our customers are insurance companies requesting these PDFs.
