How to Convert JSON to YAML, CSV, XML & Markdown
JSON is the lingua franca of APIs, but it's rarely the format you need at the finish line. Configuration files want YAML, spreadsheets want CSV, legacy and enterprise systems speak XML, and documentation wants Markdown tables. This guide covers every conversion JSON Toolkit offers, when to reach for each one, and how to do it without uploading your data anywhere.
The conversions JSON Toolkit supports
The Convert category covers the formats developers move between most often, in both directions where it makes sense:
- JSON ↔ YAML — for configuration files.
- JSON ↔ CSV — for spreadsheets and data analysis.
- JSON ↔ XML — for legacy and enterprise systems.
- JSON → Markdown — for docs, READMEs, and GitHub.
JSON ↔ YAML: for configuration files
YAML is a superset of JSON, which makes the conversion lossless in both directions — the structure and values are preserved exactly. YAML trades JSON's braces for indentation and adds comments, so it's far more pleasant to hand-edit.
That's why Kubernetes manifests, GitHub Actions workflows, Docker Compose files, and Ansible playbooks all use YAML. Convert JSON to YAML when you're turning an API response into a config file, and YAML to JSON when a tool or API expects strict JSON input.
JSON ↔ CSV: for spreadsheets and data analysis
A JSON array of objects maps naturally onto a table: each object becomes a row and each key becomes a column. The JSON to CSV converter flattens nested fields into dot-notation columns and produces properly escaped output that opens cleanly in Excel, Google Sheets, or Numbers.
Going the other way, the CSV to JSON converter auto-detects your delimiter (comma, semicolon, or tab), treats the first row as headers, and can infer types so numbers and booleans come through as real JSON values instead of strings. You can even upload an Excel or CSV file directly instead of pasting.
JSON ↔ XML: for legacy and enterprise systems
Plenty of SOAP services, financial systems, and enterprise integrations still speak XML. The JSON to XML converter produces well-formed, indented output: arrays become repeated sibling elements, keys prefixed with @ become attributes, and a #text key becomes element text content.
The XML to JSON converter reverses this exactly — attributes become @-prefixed keys, repeated elements collect into arrays, and optional type inference turns numeric text into real numbers. Because both tools use the same conventions, round-tripping between the two is stable.
JSON → Markdown: for docs and READMEs
When you want to drop data into a README, a wiki, or a pull request, Markdown is the answer. The JSON to Markdown converter turns an array of objects into a GitHub-flavored Markdown table and renders nested data as clean, indented bullet lists.
Pipes and line breaks inside values are escaped automatically, so your tables never break — the output renders correctly on GitHub, GitLab, Notion, and Obsidian.
How to convert, step by step
Every converter follows the same simple flow:
- Open the converter you need and paste your data — or drop in a file.
- Adjust any options, such as the CSV delimiter or whether to infer types.
- Review the converted output in the side-by-side panel.
- Copy it to your clipboard or download it as a file.
Why convert here instead of elsewhere
Every conversion runs entirely in your browser, so your data is never uploaded — important when you're converting real payloads or config that contains secrets. The converters are free with no limits, preserve types accurately, and handle deeply nested structures without choking. No sign-up, no watermarks, no ads.
