About Spell Checker
Spell Checker is a free online developer tool for cleaning up and transforming plain text directly in the browser.

Use it when preparing text pasted from logs, spreadsheets, emails, or documents for use in filenames, URLs, code, reports, or test data — without opening a code editor or writing a one-off script.
