About
A simple tool to match your files, made in France
Mergy brings two Excel or CSV files together on a shared column, without formulas, and gives you a clean file to import. It is built for e-commerce, purchasing and logistics teams who handle catalogs, supplier feeds and ERP exports every week.
What Mergy does
You drop your files, Mergy finds the column that links them, and shows you the result before any export: each row tells you whether it comes from both files or just one, and empty cells are flagged.
You choose which columns to keep and their order, add cleanup rules if needed, then download the result as Excel, CSV or TSV.
Our principles
Your files are not kept
They are read in your browser and processed in memory for the merge, then erased. No file content is stored.
Your codes stay intact
Every cell is read as text: barcodes keep their zeros, references do not turn into dates.
Free for small files
Up to 2 files and 15,000 rows per merge, with no sign-up. The Pro plan lifts these limits.
Hosted in the European Union
The service runs on a server in Paris. Payments go through Stripe, in Ireland.
