The shelf
Every tool is one page. No signup, no credit meter.
JSON formatter
Format, validate, minify, sort, repair and query JSON — privately.
cURL to code
Turn a cURL command into Python, JavaScript, Go, Rust, PHP, Java, C# and more.
JSON to TypeScript
Generate TypeScript types, type guards or JSON Schema from JSON.
JWT decoder
Decode, verify and sign JWTs locally — HS, RS, PS, ES and EdDSA.
Timestamp converter
Convert Unix timestamps, dates, time zones and IDs.
Cron expression parser
Explain any cron expression, see its next runs, or build one from English.
Base64 encoder
Encode and decode Base64, URL-safe, data: URIs and PEM.
JSON to Zod
Generate a Zod 4 or Zod 3 schema from a JSON sample.
JSON to Pydantic
Generate Pydantic, dataclass, attrs, msgspec or TypedDict models from JSON.
SQL to Prisma
Turn CREATE TABLE statements into Prisma, Drizzle, SQLAlchemy and more.
HTML to JSX
Convert HTML or SVG into clean JSX or a ready-made React, Preact or Solid component.
CSV to JSON
Convert CSV to JSON, JSON Lines, Markdown or SQL — and JSON back to CSV.
Runs locally
Every conversion happens in this tab. There is no upload endpoint, so your tokens and customer data can't end up on a server.
Instant by default
Static pages, client-side parsing, no round trip. Output appears as you type — including on a bad connection.
Built for the ugly inputs
Multiline cURL with escaped quotes. Nested JSON with nulls. SQL with composite keys. The annoying cases are the whole point.
Bookmark it. You'll need it at 2am.
No account to forget and no paywall to hit. Just the conversion you needed thirty seconds ago.
