File contains corrupted data
I just downloaded the most recent version of the binary. We have a costing spreadsheet that we use to build proposals. Unfortunately I cannot attach the file. It was created in Excel 2000. I opened it up in 2007 and saved as a 2007 xlsx file. When opening
it, I get the error "File contains corrupted data". I can open the xlsx file in Excel 2007 fine with no issues. I think the problem is that certain areas of some of the sheets have restrictions by Excel password protection. I took the same file from
Excel 2000, removed protection, saved to XML spreadsheet format and then to Excel 2007 format and it opened as it should in my code. Am I right to assume this error is a password protection issue? Most of the cells are writable, the formulas are what are protected.
