About This Tool

The JSON to CSV Converter transforms structured JSON data into comma-separated values, making it easy to import data into spreadsheets, databases, and analytics tools. Simply paste your JSON array of objects, and the tool flattens nested properties into clean columns with proper headers.

This converter handles a variety of JSON structures including flat arrays, nested objects, and arrays of mixed-depth records. It automatically detects column names from your data keys and lets you customize the delimiter, choose which fields to include, and control how nested values are represented.

Whether you are exporting API data for a stakeholder who prefers Excel, preparing data for a legacy system that only accepts CSV, or simply restructuring your data, this tool makes the conversion instant and painless.

Frequently Asked Questions

An array of objects with consistent keys works best - for example, [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Each object becomes a row and each key becomes a column header.
Nested objects are flattened using dot notation for column headers. For example, {"address":{"city":"NYC"}} becomes a column named "address.city" with the value "NYC".
Yes. You can choose from common delimiters including commas, semicolons, tabs, and pipes. This is useful when your data contains commas or when importing into systems that expect a specific separator.
Array values within objects are joined into a single cell using a semicolon separator by default. This keeps the CSV structure flat while preserving all your data.
The conversion runs entirely in your browser, so there is no server-imposed limit. It efficiently handles thousands of rows, though extremely large datasets may take a moment to process.
