Match by part number
Rows can move between revisions and still line up. Part numbers stay as text, so 001230 remains 001230.

THE USEFUL PART
Make the change legible.
BOM Revision Check is shaped around the handoff moment, where a clear row-level signal is more helpful than a giant spreadsheet diff.
Surface review rows
Duplicate descriptions, revisions, or prices stay visible with their conflicting values and source rows.
Keep the handoff traceable
The planned report carries Added, Removed, Changed, Unchanged, and Review rows into a shareable detail table.
CHECK THE FIT
A focused tool for flat BOM revisions.
Use it when two tabular BOMs need a clean comparison before a purchasing or engineering handoff. Review rows still need a human decision.
Planned offline download for .xlsx, .xls, and .csv BOMs.
Keeps source row references and aggregates duplicate part quantities.
Does not expand assembly trees, edit CAD, recalculate formulas, or approve engineering intent.
FAQ
Before you bring a BOM to it.
What does “flat BOM only” mean?
Each row is compared as a part-number record. Assembly-tree expansion and parent-child relationship changes are outside this focused tool.
Which files is the planned download for?
The product description covers .xlsx, .xls, and .csv BOM files. The preview on this page stays with its fixed built-in sample.
Why does a row become Review?
Review marks a conflict that deserves a human decision, such as duplicate rows with different descriptions, revisions, or unit prices. The source row numbers and values remain visible.
Is the paid download available now?
No. This is a product preview. The planned price is $19 one time, and the paid download is not available yet.
