Posted 16 February 2021, 11:55 am ESTHi,
We've got a workbook which is corrupted after saving. The only operation is opening the workbook, setting some columns to hidden and then saving the workbook. Please refer attachment for reproduction.
We expect the workbook should be open successfully after setting the hidden columns.
Please help to investigate this issue. Thanks.
By the way, we are using the GrapeCity.Documents.Excel v4.0.3.
