CSV or Excel · Max 5 MB / 10,000 rows
Drag & drop your file here, or
Select the column containing the data you want to deduplicate.
Different formatting of the same company will be matched. 'Acme Corp' = 'ACME CORPORATION INC'.
By default, matching uses only the primary column. Add other columns (like address, manufacturer, country, or location) to make matching more accurate. Each extra column has a weight that controls how much it influences the match score — total is always 100%.
Example: if Product name is 70% and Manufacturer is 30%, two rows with identical names but different manufacturers will score lower than two rows where both match.

Three simple steps. Upload your spreadsheets, let our AI match and deduplicate companies, products, contacts, and other entities, and download your clean results.
Got two lists that should be one? Here's how it works — for companies, products, contacts, and more.
Drag and drop your two spreadsheets — CSV or Excel. No formatting needed. Messy data? That's exactly what we're built for.
Our AI agent handles abbreviations, typos, missing words, and variations. Company suffixes, product SKUs, name formats — all handled. Uncertain cases are autonomously verified through multiple AI checkpoints.
Get a clean spreadsheet with every match clearly labeled — Matched, Not Matched, and AI-verified. Ready for your CRM, ERP, or reporting tool.
Upload a single list and find hidden duplicates instantly — companies, products, contacts, and more.
One spreadsheet. Pick the column to check — company names, product SKUs, contact names, or any entity you need to clean up.
Exact copies are grouped instantly. Near-duplicates like "Infosys Ltd" and "Infosys Limited" or "John Smith" and "Smith, John" are caught too. Our AI agent confirms tricky cases autonomously.
Download a deduplicated file with one golden record per group — the most complete row wins. Or download the full file with duplicate groups flagged.

Try DedupFuzzyWe believe clean data shouldn't require a team of engineers. DedupFuzzy makes enterprise-grade entity matching accessible to every business — in seconds, not days.
"Every company wastes hundreds of hours every year manually matching spreadsheets. We built DedupFuzzy to eliminate that work — so teams can focus on decisions, not data cleanup."— The DedupFuzzy Team
DedupFuzzy is built by a team of 20 engineers and AI specialists. With over 15 years of combined experience in data engineering, enterprise software, and AI, we've spent years working with large-scale entity databases across industries — from financial services and healthcare to manufacturing and SaaS.
Today, our team is focused on building AI agents that solve real data problems. DedupFuzzy is our first product — an agentic AI platform that autonomously handles the entire matching workflow — delivering results that previously required expensive enterprise software or weeks of manual work.
The principles that guide everything we build.
Your files are processed in memory and never stored permanently. We don't see, share, or retain your data.
Every match is explained. Download full results, see confidence scores, and inspect exactly how each decision was made.
No configuration. No training. No formulas. Upload a file, click a button, and get your results. That's it.
Enterprise-grade matching at a fraction of the cost. Early customers get special pricing that grows with their usage.
See what data teams are saying about DedupFuzzy.
"We had a CRM with 14,000 contacts and duplicates everywhere — slightly different spellings, old emails mixed with new ones. DedupFuzzy caught matches that our CRM's built-in dedup completely missed. Saved us days of manual work."
"I run a small e-commerce shop and kept sending duplicate marketing emails to the same customers. Uploaded my list, got clean results in under a minute. Exactly what I needed."
"The fuzzy matching is surprisingly accurate. It matched 'Johansson' with 'Johanson' and 'J. Smith' with 'John Smith' — things Excel's EXACT match would never catch."
"Way simpler than writing Python scripts for dedup. I just drag my CSV in, pick the columns, and it handles everything. My non-technical team can use it too."
"Used it to clean up a mailing list before a product launch. Found over 300 near-duplicate entries across 5,000 rows. The threshold slider is a great touch — lets you control how strict the matching is."
"Finally, a dedup tool that doesn't require a PhD to set up. Uploaded my Excel file, selected the column, and had results in seconds. No Python, no formulas, no headaches."
"We use it every month to clean our lead database before importing into Salesforce. The fuzzy match catches all the 'Inc' vs 'Inc.' and 'LLC' vs 'L.L.C.' variations. Huge time saver."
Teams that spend too much time cleaning data and not enough time using it.
Maintain clean account hierarchies, merge CRM duplicates, and reconcile lead lists from multiple sources.
