01 Load a BOM

Choose CSV or TSVUTF-8 · up to 4 MB / 10,000 rows / 100 columnsOr paste CSV

All original columns are kept, including custom fields and units.

Check duplicate part numbers and missing quantities

Load and map. Open your BOM CSV and choose its part-number and quantity columns. Map other fields you want to review.
Review the findings. Check duplicate part numbers, missing quantities and conflicting attributes against the source BOM.
Keep the result. Export every original column, or download the check report for follow-up.

A repeated part number is a review item, not proof of an error. Combine only separate occurrences that should be totalled; remove an accidental copied row instead. Conflicting attributes or units must be resolved before combining.

This is a data check for flat BOMs. It does not convert units, resolve assembly hierarchies, select replacement parts or certify a BOM for purchasing. Quantities use a dot as decimal separator with up to 6 decimal places.
