Tool information
What it does
Upload two files, choose your match keys, and download matched and unmatched exports with clear totals.
How it works
- Upload your primary file and your reference file
- Select the match key columns in each file
- Run the compare to generate matched/unmatched outputs
- Download exports and reconcile totals
Self-service comparison or managed reconciliation
The tool performs key-based matching between two files and separates rows from the primary file into matched and unmatched exports. It is not a cell-by-cell diff. Choose managed reconciliation when multiple exports, documented rules, or recurring QA and delivery are required.
FAQ
What outputs do I get?
You get matched and unmatched exports so you can reconcile lists quickly.
Can I compare by phone or email?
Yes. Choose the columns in each file that represent the key you want to match on.
Are results audit-friendly?
Yes. Outputs are separated and accompanied by clear counts so totals reconcile.
