TXT and local text files
A file-first duplicate remover for plain text
Process one or more local text files as one batch
Use upload or drag and drop when the content lives in TXT, log, Markdown, JSON, CSV, or another text file. Files read successfully are joined with a new line for the current batch.
CSV compatibility is plain-text only
The tool can deduplicate complete text rows or split raw items by a literal delimiter. It does not parse headers, columns, quoted delimiters, escaped quotes, or multiline fields.
Local processing and plain-text export
File contents stay in the browser during deduplication. Copy uses the full result, and Download saves plain-text deduplicated.txt rather than rebuilding the source file structure.

TXT dedupe FAQ
Are uploaded files sent to a server?
No. File reading and deduplication happen locally in your browser.
Does this page parse CSV headers and columns?
No. A CSV file is read as plain text. Complete rows can be deduplicated, or raw text can be split by a literal delimiter, but quoted fields and structured columns are not parsed.
What file size and batch size are supported?
The current tool accepts one or more files up to 10 MB per file and 10 MB for the accepted batch to keep browser processing responsive.
