Monday.com Excel Import Not Working

Workaround available Web Updated October 21, 2026

Quick answer

Monday.com Excel imports fail mostly because of hidden rows or columns, files over the size limit, fewer than 2 columns, or the 'skip matches' option skipping rows. Clean the spreadsheet and check the match settings.

Most likely fix: Clean the spreadsheet.

Symptoms

'File too big' or 'file too small' errors, only part of the rows imported, columns not mapped, or 'Overwrite existing items' importing nothing.

Why it happens

  • Hidden rows, blank rows or formatting in the spreadsheet
  • File over the import size limit
  • Spreadsheet with fewer than 2 columns
  • Item name column has empty values
