JSON Converters
Convert JSON to YAML, XML, CSV, TOML, TSV, SQL, HTML, Properties and INI — all in your browser.
- Turn JSON exports into YAML, XML, CSV and more.
- Pick the target format for configs, fixtures or docs.
- Stay in the browser: nothing is uploaded for sensitive payloads.
JSON → YAML
Convert JSON exports into easy-to-read YAML for Compose manifests, IaC excerpts or onboarding docs.
JSON → XML
Turn JSON into XML for partners and gateways that still require XML payloads.
JSON → CSV
Flatten JSON tables into spreadsheet rows, with dotted headings that mirror the nesting of your payloads.
JSON → TOML
Convert JSON objects to TOML for Cargo.toml, pyproject.toml and DevOps configs. Everything stays local.
JSON → TSV
Export JSON tables to tab-separated values for spreadsheets and analytics tools that prefer TSV over CSV.
JSON → SQL
Generate INSERT statements from JSON payloads to seed a database or mock a migration.
JSON → HTML
Render JSON structures as HTML tables or lists for reports and email previews.
JSON → Properties
Write Java .properties key=value files from JSON configs for Spring, Gradle and older JVM stacks.
JSON → INI
Turn JSON settings into INI sections and keys for Windows apps, PHP and lightweight config files.
JSON → TOON
Convert JSON to TOON for LLM prompts, comparing tokens and input cost against JSON as you type (AI hub).
TOON → JSON
Decode TOON back to formatted JSON with strict validation, the reverse of JSON to TOON.
