Paste a list

Or choose a file

Use MPN / Part Number and Quantity / Qty columns; Manufacturer is optional. Two-column rows or one MPN per line also work when pasted. The first XLSX sheet is used (4 MB expanded-data limit); format MPN cells as text to preserve leading zeros. Quote comma-containing MPNs in CSV. Files are parsed in your browser; only part number, quantity and optional manufacturer are sent to the 21CHIPS catalog for matching. No BOM file is stored.
