JSON to CSV essentials

How the converter works

Paste an array of JSON objects and the tool merges every key into a unified header row. Missing fields are left blank so the resulting CSV can be loaded into spreadsheets without manual cleanup.

Supports nested objects by flattening top-level keys.
Preserves number, boolean, and string values as plain text.
Automatically escapes commas, quotes, and newlines to stay RFC 4180 compliant.

Why convert JSON to CSV?

Import API responses into Excel, Google Sheets, or Airtable for quick analysis.
Share datasets with teammates who are more comfortable with tabular formats.
Prepare snapshots of application logs or metrics for BI tools that expect CSV uploads.

Troubleshooting tips

Use the Pretty Print button to reformat JSON before editing so syntax errors stand out.
Ensure the JSON root is an array—wrap single objects in square brackets.
If you see empty columns, check that every object contains the same key name.
