DevT Pro: Developer Tools

Format, convert, validate and inspect JSON, XML, YAML, CSV, TOML and more on your iPad. DevT Pro puts 120 developer tools in one fast, offline app with a real code editor, tabs and a command palette. No subscription. No ads. No account. Everything runs on your iPad, so the payloads, tokens and logs you paste stay on your device. WHY DEVELOPERS USE DEVT PRO • One app instead of dozens of websites full of ads and trackers • Works offline: on a plane, on a train or behind a strict firewall • Code editor with syntax highlighting, line numbers, folding, find, smart indentation and touch selection • Tabs: duplicate a tab to compare two versions of a payload • Command palette and shortcuts with a hardware keyboard • Open and save through the Files app, iCloud Drive and other providers • Light and dark themes, Split View and Stage Manager NEW: SCHEMA VALIDATION Validate JSON and YAML against JSON Schema (draft 4 to 2020-12) and XML against XSD. Load a schema from a URL or the Files app. Referenced schemas are saved with it, so your recent schemas keep working offline. Tap an error to jump to its line. NEW: SHORTCUTS AND DEEP LINKS Create devtpro:// links that open a tool with your text already filled in. Use them in Shortcuts, Safari or Notes. WHAT'S INSIDE Converters: JSON, XML, YAML, CSV, TSV, TOML and TOON in every useful direction, plus CSV or TSV to HTML table, JSON to JSON Schema and XML to XSD.
