About CSV to Excel
CSV to Excel turns comma-separated exports into .xlsx workbooks with proper columns — fixing the “everything in column A” problem when double-clicking a CSV.
Keep a header row, watch delimiter assumptions, and re-export from the source system as UTF-8 when you see garbled characters.
After conversion, open in Excel or Sheets as usual.
