CSV to JSON Converter: Free Online Tool & Complete Guide

What is the CSV to JSON Converter?

CSV (comma-separated values) is the universal format for spreadsheet data, but most applications and APIs want JSON. Converting by hand is slow and error-prone — especially when values contain commas, quotes or newlines.

This CSV to JSON converter parses CSV with proper quote handling and turns it into a clean JSON array of objects, using the first row as keys. It supports custom delimiters (commas, semicolons, tabs) and can also convert JSON back to CSV for round-tripping your data. Everything runs locally — your data never leaves your browser.

Frequently asked questions about the CSV to JSON Converter

Here are the answers to the questions people ask most about the CSV to JSON Converter.

• How are commas inside quoted values handled? — Values wrapped in double quotes are parsed as a single field, so commas inside them do not split the row. This converter follows the RFC 4180 standard.
• What if my file uses semicolons as delimiters? — Select the semicolon delimiter option — a common format for European spreadsheet exports.
• Can I convert JSON back to CSV? — Yes, switch to JSON → CSV mode and paste a JSON array of objects. The first object's keys become the header row.
• Is my data sent to a server? — No. Conversion happens locally in your browser, so sensitive spreadsheet data never leaves your device.
