Error message

Failed to save target content: Duplicated column names are not allowed (Pas dapos; impact négatif")

I get this error message because I have Excel files embedded into a PPT document, and all columns are named "column1". I tried changing all of them (over a hundred) as column1, column2, colum3, etc. to no avail. Any ideas?

Many thanks in advance!
