CSV to JSON Converter

Switching between CSV and JSON formats is a common task for developers, data analysts, and anyone working with structured data. This free online converter handles both directions instantly: paste comma-separated values to get a JSON array of objects, or paste JSON data to produce a clean CSV table. No software to install, no file uploads, and no data sent to a server.

What does the CSV to JSON converter do?

Whether you have some JSON code or some CSV code that you want converting into the new format, you can use the tool above to automatically do that for you.

Simply copy the data you have into the above field, JSON code into the JSON field and the CSV data into the CSV field and then you can see it automatically be converted into your desired format in the field next to it. Copy it and then paste it where you need to.

What is the difference between CSV and JSON?

CSV (Comma-Separated Values) stores data in a flat, tabular format where each line represents a row and commas separate individual fields. It is compact and widely supported by spreadsheets and databases. JSON (JavaScript Object Notation) uses key-value pairs and supports nested structures, making it the standard format for web APIs and configuration files. Choose CSV when you need simple, flat data that opens easily in Excel or Google Sheets, and JSON when you need hierarchical data or are working with web services. Once you have your JSON output, you can clean it up with the JSON formatter.
