JSON to CSV Converter

Convert

Convert JSON to CSV online — transform any JSON array or JSON format into spreadsheet-ready CSV for Excel or Sheets.

Convert JSON to CSV for Excel and Sheets

A JSON array of objects maps naturally onto a spreadsheet: each object becomes a row and each key becomes a column. This converter does exactly that, producing properly quoted and escaped CSV that opens cleanly in Excel, Google Sheets, Numbers, or any data tool — no broken columns, no mangled commas.

Nested fields are flattened into dot-notation columns, so a structure like { user: { name } } becomes a user.name column rather than a blob of JSON in one cell.

Convert JSON format to CSV — any structure

Whether your JSON format is a flat array, a deeply nested object, or a mix of types, this converter handles it. Flat arrays convert directly — keys to headers, values to cells. Nested objects and arrays are flattened into dot-notation columns so every field gets its own column instead of being crammed into a single cell as raw JSON.

Converting JSON format to CSV is lossless for scalar values: strings stay strings, numbers stay numbers, and booleans become true/false. The only transformation is structure — from hierarchical JSON to the flat rows and columns a spreadsheet expects.

Transform JSON to CSV online — no install, no upload

To transform JSON to CSV online, paste your array into the editor or upload a .json file — the conversion runs immediately in your browser and the result is ready to copy or download. Nothing is sent to a server, which means you can safely change JSON to CSV or convert JSON in CSV format even when the payload contains API keys, user data, or other sensitive information.

The conversion of JSON to CSV is a one-step operation: choose your delimiter (comma, semicolon, or tab) to match the spreadsheet tool or locale you are targeting, and the output is properly escaped — values containing quotes, commas, or line breaks are wrapped correctly so the file imports without errors.

Delimiters and formatting

Not every spreadsheet expects commas. Choose comma, semicolon, or tab as your delimiter to match your locale or destination tool — semicolons are common in European Excel, tabs produce TSV. The first row is written as a header of column names, and values containing the delimiter, quotes, or line breaks are escaped automatically so the file always parses correctly.

Export JSON to CSV or Excel online

Sometimes the fastest way to analyze JSON is in a spreadsheet. Convert a JSON array to CSV online and open the result directly in Excel, Google Sheets, or Numbers — headers from your keys, one row per object, and nested fields flattened into clear dot-notation columns. Pick the delimiter your locale expects and the file imports cleanly every time.

Frequently asked questions

An array of flat objects converts directly — keys become column headers and each object becomes a row. Nested objects are flattened using dot notation.

Yes. The output is standard, properly escaped CSV that imports cleanly into Excel, Google Sheets, Numbers, and any data tool.

Nested fields are flattened into dot-notation columns — a value at user.address.city becomes its own column — so even nested JSON exports cleanly to a flat CSV that opens in Excel or Google Sheets.

Paste your JSON array into the editor — the converter accepts any valid JSON format and produces a CSV file instantly. Each object in the array becomes a row, keys become column headers, and nested fields are flattened into dot-notation columns. You can then copy the result or download it as a .csv file ready for Excel or Google Sheets.

Yes. Nested objects are flattened automatically using dot notation — for example, a field at user.address.city becomes its own CSV column rather than a JSON blob. This means you can transform complex, nested JSON to CSV and still get a clean, readable spreadsheet.
