About this comparison tool
Count duplicate entries
Paste one value per line. The tool shows the number of occurrences and the number of extra copies, letting you export a report without modifying the original list.
Finding near-duplicates
This version compares normalised text with optional space and case settings; it does not perform fuzzy matching for misspellings.
Frequently asked questions
Can I check repeated postcodes or order numbers?
Yes. Paste one entry per line, or change the input separator to commas.
Will it delete duplicates?
No. It only identifies and counts duplicates, preserving your original text.
