Hi Rob,

I not able to open the excel file:

Error message:"Excel found unreadable content in "job size randomness.xlsm" Do you want to recover the contents of this workbook? If you trust the source of this workbook, click yes."

When i clicked yes, the repaired file is blank.

The repaired record:
Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.
Removed Records: Worksheet properties from /xl/workbook.xml part (Workbook)

How to fix this error? I really hope to try your solution.

Regards,
SC
