Free Online Text & Developer Tools

Text tools cover the small jobs that interrupt coding and writing: format JSON, encode a URL, hash a string, generate a UUID, clean whitespace, or build a slug. Almost everything here runs in your tab so paste stays private. Subgroups below keep hundreds of utilities crawlable without dumping one endless grid.

Text and developer tools typically run in your browser. Paste stays in the tab unless a tool explicitly uploads.

Text utilities pack — word counter, case converter, line tools, find & replace, slugs, and UTM links.

Pick the right text utility

For API debugging, start with JSON Formatter or Validator, then JSON Path if you need a field deep in a payload. For public IDs, compare UUID, Nano ID, and ULID generators before you lock a schema.

Encoders are for transport, not secrecy — Base64 is reversible. Use hash tools for fingerprints, not password storage (use a real KDF in your app). Password Generator pairs with the strength meter when you need a memorable-enough secret for a new account.

Keep inputs minimal: paste only the snippet you need so results stay easy to scan.

Text Tools FAQ

Do these tools send my text to a server?
Local text tools process paste in your browser. Your string stays in the tab for those utilities.
JSON formatter vs validator?
Formatter pretty-prints. Validator checks syntax and reports errors. Use both when a payload looks right but still fails an API.
Are developer tools free?
Yes. Everyday formatters, generators, and encoders on FileToolsHub are free with no account required.
Why so many text tools?
Each page targets one job so search and bookmarks stay precise. Use the subgroups below — or search from the sitemap — instead of scrolling one giant list.
