BOM CSV Checker: Missing Fields & Duplicate References
Find missing manufacturer part numbers, invalid quantities and duplicate reference designators before requesting a sourcing review. The CSV stays in your browser. The checker does not access component distributors or validate footprints, electrical ratings or authenticity.
BOM CSV checker — catch missing data and duplicate references
Choose a CSV with MPN, Qty and RefDes columns. Files stay in this browser. This tool checks structure; it does not confirm part availability, authenticity, footprint compatibility or electrical suitability. Expand reference ranges such as R1–R3 first.
Use the result in a reviewed RFQ
Keep the board revision, quantity, material ownership and test coverage with the result. Resolve missing values with the team responsible for the build. A planning output is useful context for a conversation; it is not a manufacturing approval or a binding commercial offer.
