JSON Input

CSV Output

Quick answer

To convert JSON to CSV online, paste your JSON array of objects into the KaviForge JSON to CSV Converter, select your delimiter (comma, semicolon, tab, or pipe), and click "Convert to CSV". Copy the result or click download to save a `.csv` file that opens directly in Excel or Google Sheets.

APIs, NoSQL databases, and web apps export data as JSON, while business teams, spreadsheets, and BI tools expect CSV rows and columns. This converter bridges the gap in seconds without uploading your data to any server.

Object keys from your JSON array become the CSV header row, and values containing commas, quotes, or line breaks are automatically escaped according to RFC 4180 CSV standards.

How JSON to CSV Conversion Works

A JSON array of objects (`[{"name":"Ada","role":"Engineer"}]`) maps naturally to a tabular spreadsheet: the property names of the objects define the column headers, and each object in the array becomes a row.

When a string value contains the delimiter character (such as a comma inside an address) or quotation marks, the converter wraps the field in double quotes and escapes internal quotes as `""` so spreadsheet software parses every column accurately.
