Developer Data Format Converters — All in One Place

Modern software development involves working across a wide range of data serialization formats. An API might return JSON, your configuration might be TOML, your CI/CD pipeline uses YAML, and a legacy system expects XML. Converting between these formats manually is tedious and error-prone. These tools automate the conversion completely in your browser — no server round-trip, no data leakage, no account required.

JSON Converters

The JSON to XML converter maps JSON keys to XML element names, handles nested objects as child elements, and converts JSON arrays to repeated sibling elements with a configurable tag name. The JSON to TOML converter outputs TOML tables for nested objects and arrays of tables for object arrays. The JSON to JSON Schema generator infers a Draft-07 or 2020-12 schema from a sample, detecting email, date, and URI string formats automatically. The JSON to HTML Table tool converts JSON arrays to styled tables with Bootstrap or Tailwind class options and a live preview tab. The JSON to Markdown tool auto-detects the best Markdown format — tables for arrays of objects, bullet lists for nested objects, or fenced code blocks — with a live rendered preview.

XML and YAML Converters

The XML to YAML converter parses the full XML DOM and rebuilds it as a YAML tree, mapping attributes to @attr keys and collapsing repeated sibling elements into YAML sequences. The YAML to XML converter handles the reverse, supporting the most common YAML patterns used in DevOps tooling like Docker Compose, Kubernetes manifests, and GitHub Actions workflows.

TOML Converters

The TOML to JSON converter handles all TOML constructs including standard tables, array-of-tables, inline tables, and all scalar types including hex and octal integers and ISO 8601 datetime strings. It's particularly useful for reading Cargo.toml, pyproject.toml, or Hugo configuration files in tools that only accept JSON input.
