Fuzzy Matching Tool
Match similar text and data online — free. Find matches that VLOOKUP and exact-match tools miss. Handles typos, abbreviations, different spellings, and formatting variations automatically.
How the Fuzzy Matching Tool Works
Unlike exact-match tools that require identical text, fuzzy matching calculates similarity scores between text strings. "Acme Corp" and "ACME Corporation" aren't identical, but they're 87% similar — and obviously the same company to a human.

Frequently Asked Questions
What is a fuzzy matching tool?
A fuzzy matching tool compares text strings and finds similar matches even when they're not exactly identical. It uses algorithms to calculate similarity scores, catching typos, abbreviations, different spellings, and formatting variations that exact-match tools miss.
Is this fuzzy matching tool free?
Yes, DedupFuzzy offers a free tier for up to 500 rows with no signup required. You can upload your CSV or Excel file and get fuzzy matching results immediately. Larger files require a free account.
What file formats does the tool support?
The tool supports CSV and Excel files (.xlsx, .xls). Simply export your data from any spreadsheet application and upload it directly to the tool.
How accurate is fuzzy matching compared to VLOOKUP?
Fuzzy matching typically finds 3-5x more matches than VLOOKUP or exact-match tools. VLOOKUP only works when text is identical character-by-character. Fuzzy matching catches variations like "Acme Corp" vs "ACME Corporation" that VLOOKUP completely misses.
Is my data secure?
Yes. Your data is processed in memory and never stored on our servers. Files are deleted immediately after your session ends. We do not share, sell, or retain any of your uploaded data.
Can I match two different lists together?
Yes. DedupFuzzy supports both single-list deduplication (find duplicates within one file) and two-list matching (find which records in List A match records in List B).
