How it works under the hood
Click on each heading for more details
Select Your Columns
Choose a main column for deduplication, then optional supporting and categoy columns for context and refined results.
Creating the "Essence"
The system simplifies the main column by creating "essence" of the content - stripping away special characters and spaces for accurate comparison.
Advanced "Fuzzy" matching
Using the Levenshtein distance, the algorithm calculates how closely rows match. Adjust sensitivity to fit your needs.
Choose Your Export Options
Once duplicates are identified, you decide what to do next. Merge duplicate rows into a single entry, remove duplicates while keeping the first instance, or flag duplicates with a unique ID in a new column for easy identification (with ID -1 indicating no duplicates).

About your files
Your spreadsheets remain exclusively yours, processed by our algorithm and not viewed by humans — unreachable even by our admins. Files are securely erased from our servers every 24 hours. Registered users can delete their files at any time, and older files are deleted monthly. Your files security is a top concern!
