Excel found unreadable content in

[h0rseduck]

Hello. I need to create a file with a huge number of columns and set the width for all of them. When forming a file with more than 1024 columns, I get an error when opening the file "Excel found unreadable content in '[filename].xls'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes."

Most likely, this is due to this code, because if I increase the max parameter in this line, then everything works for me.
