Datasheet Lens can now compare its component record with bill of materials (BOM) exports from KiCad, Altium, Eagle, and Fusion without requiring every tool to name its columns the same way. It also reports when a symbol's manufacturer part-number field names one device while its value field names another, a quiet inconsistency that usually reaches procurement or assembly before anyone notices.
The checker accepts comma, semicolon, and tab-separated files, handles the common Windows text encodings, and recognizes variants such as MPN, Manufacturer Part Number 1, and Mfr PN. It skips parts marked do not populate, keeps alternate orderable parts, and ties each finding back to the schematic reference. When two fields disagree, the report says which part it used and tells the reviewer that one field must change instead of silently choosing a value.
This is the unglamorous parsing work required before an automated BOM review can be trusted. The project is new, and its heuristics will meet manufacturer codes that look like resistor values or generic symbol names. Its tests already cover those ambiguous cases. Board teams can run the checker on a known design and inspect every conflict before allowing it to suggest any part change automatically.
