I clean, deduplicate, and merge CSV or Excel files using a purpose-built tool I run daily for my own real, active business, not manual spreadsheet work.


Smart matching catches duplicates a basic dedupe misses: different casing, extra spaces, and formatting differences that look identical to the eye but trip up standard tools.


What I can do for you:

Remove duplicate rows with smart, real matching

Merge multiple CSV or Excel files into one clean file

Standardize formatting so your data is ready to use


Your file is never uploaded to a server, so there's no privacy risk. If you send me a messy file, you'll get a clean one back, plus a short note on what I fixed.
