JSON to CSV Converter Online — Free Tool

Transform complex JSON arrays and nested objects into clean, exportable CSV files locally within your browser.

JSON
Supports a JSON array of objects or a single object.
Privacy note: All processing happens entirely in your browser. No data is sent to our servers.

About this tool

JSON arrays of objects flatten naturally into spreadsheet rows. This tool converts structured JSON into CSV with a header row derived from object keys.

Ideal for exporting API responses to Excel, Google Sheets, or legacy systems that expect comma-separated input.

Common use cases

  • Exporting API data for business users in Excel
  • Flattening nested JSON reports where supported
  • Preparing test fixtures from JSON samples
  • Sharing structured data with non-technical stakeholders

How to use

  1. Paste a JSON array of objects into the input panel.
  2. Ensure objects share consistent keys for clean columns.
  3. Review the CSV output with quoted fields where needed.
  4. Copy or download the CSV for spreadsheets or imports.

Understanding the result

  • Column order follows keys from the first object or a union of all keys.
  • Nested objects may stringify or flatten depending on tool behavior—check output before import.
  • Special characters and commas in values are escaped with quotes in valid CSV.
  • Empty arrays or non-object JSON may need formatting before conversion succeeds.

FAQ

What JSON shape is required?

An array of flat objects converts best: [{"name":"A","age":1}, ...]. Single objects can often be wrapped in an array.

How are nested fields handled?

Deep nesting may appear as JSON strings in a cell or be flattened. Inspect output for your import target.

Can I open the CSV in Excel?

Yes. Download or copy into a .csv file. Excel may prompt for delimiter and encoding on open.

Does key order matter?

CSV is positional. Key order in the first object typically defines column order.
