Good Morning!
Guys, I have a directory with several spreadsheets exported from my system in XLS format (Excel format 97 - 2003), I need to write a script to go through this directory and convert these spreadsheets to XLSX. The XLDR and Openpyxl libraries cannot read my spreadsheets, due to the format.
Could someone give me a hand, or indicate some library?
I accept tips in C# and Java as well
With C# you can useSpire.XLS:
workbook.LoadFromFile("Input.xls");
workbook.SaveToFile("Output.xlsx", ExcelVersion.Version2013);
