Everything you need to know about using TextLab on iPhone and iPad - case and JSON, Markdown and regex, encoders and AI text actions, and how to chain them into one-tap workflows.
TextLab: Format, Edit & Convert
View product page →
Case conversion (UPPER/lower/Title/snake/kebab/camel/Pascal/CONSTANT), JSON pretty-print and minify, Markdown preview, text cleanup (whitespace, smart quotes, zero-width chars, BOMs), encoders (Base64, URL, HTML entities, hex, JWT decode), regex test and replace, diff/compare, quick conversions (timestamps, hex-to-RGB, CSV-to-JSON), and AI text actions (summarize, rewrite, fix grammar, translate, explain).
Yes for the local actions (case, JSON, Markdown, regex, encoders, diff, cleanup, conversions). AI text actions need a network connection if you opt into the cloud-AI option; on-device AI runs without internet on supported chips.
Local actions never leave your device. AI actions show a clear consent prompt before sending text anywhere, and only when you explicitly trigger them. You can disable cloud AI entirely in settings.
Workflows let you chain actions together (for example: clean whitespace → JSON pretty-print → copy) and save the chain as a one-tap shortcut. Useful for tasks you repeat many times a day.
ICU regex (the same as NSRegularExpression on iOS, similar to PCRE2). Most JavaScript, Java, and Python patterns work directly. The cheat sheet inside the app calls out the small differences.
Yes. Every result has Copy, Share Sheet, and "Send back to source" options. TextLab also exposes a Share Extension so you can send text from any app into a TextLab action and back.
Yes. TextLab provides App Intents so you can call any action (or saved workflow) from Shortcuts, the Action Button, Spotlight, or Siri.
A fast text toolbox for iPhone and iPad. Format, edit, convert, and run AI actions, all in one app.
Take a one-line API response and turn it into something you can actually read.
Strip smart quotes, zero-width characters, and extra whitespace in one tap.
