JSON Converters

Auto Detect

Input

Paste or type JSON, Base64, or plain text…

Paste or click a sample above — it will be detected automatically.

One JSON document, eight destinations

JSON is the lingua franca, but downstream systems still speak Java classes, XML feeds, YAML configs, spreadsheets and HTML tables. Paste your document once and switch targets from the rail: each converter maps arrays and objects to idiomatic output for its format. Conversions run entirely client-side — paste internal payloads freely.

Frequently asked questions

How do I convert JSON to Java classes?

Pick JSON → Java in the workspace, paste your document (or an example response), and generate POJO-style class definitions matching the structure — ready to drop into a project.

Which target formats are supported?

Java, XML, YAML, CSV, TSV, Excel-compatible tables, plain text and HTML. Each converter maps JSON structure to its target's conventions — arrays become repeating elements or table rows.

Can I convert nested JSON to CSV?

Objects at the top level become table rows; nested objects and arrays inside a row are kept as JSON text in the cell so nothing is lost. If you need every nested field on its own column, flatten the keys first so the document is a flat array of objects.

My conversion failed — is my JSON invalid?

Most failures are syntax problems upstream. Validate the document first with the JSON Validator, then return here to convert the clean version.

Do conversions upload my data anywhere?

No. Every converter parses and generates output inside your browser. Nothing you paste is transmitted, logged or stored.
