## How it works

1. Paste your text into the editor.
2. Pick a mode (trim, dedupe, sort, case, replace, or remove empty) and set the options.
3. Process and download the cleaned.txt file.

## Use cases

- Clean up a copy-pasted list of emails before importing into a CRM.
- Remove duplicate rows from a list of URLs scraped from a site.
- Sort a long word list alphabetically before sharing.
- Bulk-convert a paragraph to Title Case or lowercase.
- Find-and-replace across hundreds of lines without opening a text editor.

## Frequently asked questions

### Does the find-and-replace support regex?

Yes. Tick 'Use regex' on the Replace tab and your Find field is treated as a regular expression. Case-insensitive is a separate checkbox.

### How large a text can I clean?

Up to 2 MB per job, which is hundreds of thousands of lines for typical content. Split larger batches into separate runs.

### What's the difference vs a code editor?

Zero install, and the result is one downloadable file. Perfect for cleaning a list before pasting it into a spreadsheet or CRM.
