CSV works best with flat rows. Nested JSON object keys are converted to dot notation, while array values remain valid JSON strings so information is not silently discarded.

What is JSON to CSV Converter?

JSON to CSV Converter turns a JSON object or array of records into tabular text that spreadsheets and import tools can read. It discovers columns, flattens nested object keys with dot notation, and safely quotes cells containing delimiters, quotes, or line breaks.

How to use JSON to CSV Converter

  1. 1.Paste a valid JSON object or array into the source editor.
  2. 2.Select comma, semicolon, tab, or pipe as the delimiter and choose whether to include headers.
  3. 3.Convert the records and inspect how nested values and arrays appear in the preview.
  4. 4.Download the CSV or copy it into the destination spreadsheet or import workflow.

Key features

  • ✓Single objects become one data row while arrays produce multiple rows.
  • ✓Nested object paths are flattened into columns such as customer.address.city.
  • ✓Column discovery accommodates records that do not all contain identical keys.
  • ✓RFC-style quoting protects delimiter characters, double quotes, and embedded line breaks.
  • ✓Alternative delimiters support regional spreadsheets and system-specific imports.

Common use cases

  • Export API response records for analysis in a spreadsheet.
  • Turn a small JSON inventory into a merchant import file.
  • Flatten webhook samples for a QA comparison table.
  • Create tab-separated data for pasting into a database client.

Frequently asked questions

Can one JSON object be converted to CSV?

Yes. Its keys become headers and its values form a single data row.

How does the converter handle nested JSON objects?

Nested keys are flattened with dot notation so structured values can occupy predictable CSV columns.

What happens to arrays stored inside a JSON record?

Nested arrays are retained as compact JSON text inside one cell because CSV has no native array type.

Why are some CSV values surrounded by double quotes?

Quoting preserves delimiters, quote characters, and line breaks as part of one cell rather than splitting the record incorrectly.

Will every row have the same columns?

Yes. The converter builds a combined header set and leaves a cell empty when a particular record does not contain that field.
