Text Deduplicate & Sort
Free online text deduplication tool, sort and remove empty lines
Text Deduplication Use Cases
Remove duplicate lines from lists, email addresses, URLs, log entries, or any text data. This tool helps clean up data by removing duplicate entries, sorting lines alphabetically, trimming whitespace, and removing empty lines — all common tasks when processing text files, CSV data, or pasted content.
How to Deduplicate and Sort Text
Paste your text with one entry per line. Use the Remove Duplicates button to eliminate duplicate lines. Sort alphabetically (A-Z or Z-A) with the sort buttons. Trim whitespace and remove empty lines with the corresponding options.
▶Is the deduplication case-sensitive?
Yes, by default Apple and apple are considered different entries. Trim whitespace first if you suspect leading or trailing spaces are causing false duplicates.
▶Does this tool preserve the original order?
Remove Duplicates preserves the order of first occurrence. Use the sort buttons if you want alphabetical ordering instead.
▶Can I process large text files?
Yes, the tool handles thousands of lines in your browser. For extremely large files (millions of lines), the browser may slow down.
