Preparing a BOM for upload: common mistakes in Excel

A clean bill of materials uploads in seconds. A messy one turns into a row-by-row clean-up. Most issues come from a handful of recurring formatting habits.

Keep the columns predictable

A part-number column and a quantity column are the minimum. Keep headers in the first row, one part per row, and avoid merged cells — they break the import.

  • One part per row. Do not pack several MPNs into a single cell.
  • No merged cells. They shift the grid and rows stop aligning to columns.
  • Plain quantities. Numbers only — drop units, notes and ranges from the qty column.
If a row is not recognised, it is almost always the part-number column — check for stray spaces, line breaks and trailing notes.
