JSON Converters
Take JSON and turn it into whatever the next system needs — XML, CSV, YAML, HTML, plain text, TSV or a real Excel workbook. All free, all in your browser.
JSON to XML
Map JSON objects to XML elements for SOAP, RSS and enterprise systems.
JSON to CSV
Flatten arrays of objects into spreadsheet-ready comma-separated rows.
JSON to Excel
Generate a real .xlsx workbook you can open straight in Excel or Sheets.
JSON to YAML
Produce clean YAML for CI pipelines, Docker Compose and Kubernetes.
JSON to HTML
Render JSON as an HTML structure you can drop straight into a page.
JSON to Text
Extract readable key/value text from nested JSON for quick scanning.
JSON to TSV
Tab-separated output that pastes cleanly into databases and sheets.
One format in, many formats out
JSON is the lingua franca of web APIs, but the systems around it rarely speak it. Spreadsheets want CSV or XLSX, legacy services want XML, infrastructure tooling wants YAML, and a quick report wants plain text. These converters bridge that gap: paste JSON once and get the exact shape the next tool expects.
Every converter parses your JSON first, so malformed input is caught immediately rather than producing a broken file. And because the work happens entirely in your browser, you can convert API responses containing tokens or customer data without anything being uploaded.
Which converter do I need?
- Going into a spreadsheet a colleague will edit? Use JSON to CSV or JSON to Excel.
- Feeding an older SOAP or enterprise API? JSON to XML.
- Writing config for CI, Docker or Kubernetes? JSON to YAML.
- Loading rows into a database or analytics tool? JSON to TSV.
- Need to debug or just read the data? Pretty-print it with the JSON Formatter first.
Frequently asked questions
No. Every converter in this suite runs entirely in your browser using JavaScript. Your data is never transmitted, logged or stored — close the tab and it's gone.
Tabular formats like CSV and TSV flatten nested structures into dotted column names, while XML, YAML and HTML preserve the full hierarchy. Each tool's page explains exactly how it handles nesting.
Yes. The JSON to Excel tool generates a genuine .xlsx workbook (not just CSV renamed), so it opens natively in Excel, Google Sheets and Numbers with proper cells and columns.
Many formats round-trip — for example our XML to JSON converter reverses JSON to XML. YAML and CSV can also be brought back to JSON with the matching tools.
Conversions run in memory in your browser, so they comfortably handle files up to several megabytes. Very large files depend on your device's available memory.
No. Everything is free and works directly in the browser on desktop and mobile — no account, no extension, no download.
