About this tool
The text toolkit bundles everyday list and text operations: remove duplicate lines, remove empty lines, sort alphabetically, trim whitespace, number lines and reverse order. It can also extract email addresses and IPv4 addresses from any text and validate their format — handy for cleaning mailing lists, logs and datasets without spreadsheets.
FAQ
Does removing duplicates keep the first occurrence?
Yes — the first occurrence stays and later duplicates are removed.
How does email validation work?
Each extracted address is checked against standard email format rules (name@domain.tld). It checks format, not whether the inbox exists.
Is my text uploaded?
No — all processing happens locally in your browser.
