Free JSON Converter Online
A JSON converter takes a JSON document and rewrites the same data in another format: a CSV row set for a spreadsheet import, a well-formed XML tree for a SOAP client, a block-style YAML file for a Kubernetes manifest, or a tab-separated text block ready to paste into Excel. A good converter also runs the reverse trip, parsing CSV or XML back into a typed JSON array so the round trip never breaks the shape of the data.
When a spreadsheet import needs CSV, a config file needs YAML, or a legacy endpoint expects XML, you are looking at the same data in the wrong format. Converting by hand means writing the mapping logic each time, and nested arrays make it worse. Our JSON Converter handles JSON to CSV, XML, YAML, and TSV plus the reverse trip, all from one editor running locally in the browser.
Converting JSON in Four Steps
- Load your source: paste JSON, CSV, or XML into the left pane, drop a .json, .csv, .tsv, .xml, or .txt file onto the workspace, or click Upload.
- Pick a conversion mode: tap JSON to CSV, JSON to XML, JSON to YAML, JSON to TSV, CSV to JSON, or XML to JSON from the toolbar.
- Hit Convert: the right pane fills with the converted output and the status bar shows input and output size plus any parse errors.
- Download or copy: grab the result with Copy or save it with the correct .csv, .xml, .yaml, .tsv, or .json extension via Download.
