About the Code Format Converter

This code format converter moves data between JSON, YAML, CSV and Base64 and converts colour formats, all from one page — useful when a debugging session needs three different conversions in as many minutes.

A code format converter in one place suits the way conversion actually comes up. You rarely need one conversion in isolation: a response arrives as JSON, the config wants YAML, a colleague wants CSV, and something in the middle is Base64 encoded.

The pairings here are the ones that recur. JSON and YAML express the same structures with different syntax, CSV flattens either into rows, and Base64 wraps anything into transport-safe text.

Everything runs in your browser, which matters because the data being converted is usually a real API response or config value rather than a sample. For a single conversion done thoroughly — with type detection and options — the dedicated converters under Converters go further.

How to use the Code Format Converter

  1. Choose the conversion. Pick your input and output formats.
  2. Paste your data. Enter the JSON, YAML, CSV or encoded string.
  3. Convert. The result appears immediately.
  4. Copy the output. Take the converted data.

Frequently asked questions

Which conversions are available?

JSON to and from YAML, JSON and CSV, Base64 encoding and decoding, and colour format conversion.

When should I use a dedicated converter instead?

When you need options — delimiter control, type detection, custom root elements. The Converters category goes deeper on each pairing.

Is my data uploaded?

No. Every conversion here runs in your browser.

Are types preserved converting JSON to YAML?

Yes. Numbers, booleans and nulls carry across, with quoting added where YAML would otherwise misread a value.

Is there a size limit?

Nothing fixed. Large inputs are limited only by your device's memory.
