Free Online Text and Developer Tools for everyday tasks
Clean up text copied from documents, count words and characters, compare revisions, validate JSON or encode text for web use. Check the result before reusing it in code, a form, an article or another system that expects a specific format.
Choosing the right tool
Start with the exact task you need to complete, then choose the matching workspace. Check input requirements and review your result before relying on it. Toolnook provides general-purpose helpers; it does not replace official tax, legal, medical or financial guidance.
Frequently asked questions
Do text counters include spaces?
The tool labels indicate the counts it provides. Character totals can differ depending on whether spaces, line breaks and Unicode characters are included.
Can I use the JSON formatter to fix invalid JSON?
A formatter can show valid structure or report a parse error, but you may need to correct the underlying syntax first.
Is pasted text stored?
The browser-based tools are designed to process input locally where indicated. Do not paste sensitive information unless the specific tool’s privacy behavior is suitable for it.
Calculations are estimates where inputs or local rules vary. Always check official requirements for tax, legal, immigration or health-related decisions.
