Compare two files and see what matches, what doesn't, and what's missing.
100% Private: Data never leaves your machine
Upload any two files below — spreadsheets, CSVs, or exports from different systems. Meridian automatically finds matching records, highlights differences, and flags anything worth a second look.

A date like 01/02/2026 is ambiguous (Jan 2 or Feb 1?) — set this if the automatic guess seems wrong.

This doesn't decide whether records match — it just flags a warning if a matched pair disagrees on these fields too.
Differences this small or smaller still count as matching (handles rounding).
Only used if you set a date column above.
Also tries near-matches (typos, formatting, split payments). Turn off to require exact matches only.
Only matters if Smart Matching is on. e.g. INV12345 vs INV12346 could still match on Loose.
