ToolsSoup's CSV to JSON converter is a free online tool that turns CSV — from a spreadsheet, database export, or report — into a clean JSON array of objects. It uses the first row as keys, handles quoted fields and commas, and can convert numbers and booleans automatically. Everything runs in your browser — no uploads, no sign-up, and nothing ever leaves your device.

      

        
What is a CSV to JSON converter?

        
A CSV to JSON converter reads comma-separated values — the format spreadsheets and databases export — and rewrites it as JSON, the format APIs and JavaScript prefer. The first row becomes the keys, and every following row becomes an object. It is the quickest way to turn a spreadsheet into data you can drop into code, a config file, or an API request.

How does it handle quotes and delimiters?

        
The parser follows the common CSV rules: a field wrapped in double quotes can contain commas, line breaks, and escaped quotes (written as two double quotes). You can switch the delimiter between comma, semicolon, and tab to match files exported in different regions. With type parsing on, values that look like numbers or true and false are converted; otherwise every value stays a string.

How are CSV headers used?

          
The first row of your CSV is treated as the header and becomes the keys of each JSON object. Every row after it becomes one object in the array.

        

        

          
Does it handle commas inside values?

          
Yes. Any field wrapped in double quotes can contain commas, line breaks, and escaped quotes, exactly as the CSV standard specifies.

        

        

          
Will numbers stay numbers?

          
If you enable parsing, values that look like numbers or booleans become real JSON numbers and true/false. Turn it off to keep every value as a string — useful for IDs and zip codes with leading zeros.

        

        

          
Is my data safe?

          
Absolutely. All conversion happens locally in your browser using JavaScript, so your CSV is never sent to or stored on any server.
