CSV to JSON Converter
Convert CSV files to JSON format instantly with custom delimiters.
Why this conversion is still a daily dev task
Spreadsheets export CSV for everything from analytics exports to back-office data pulls. Many APIs expect JSON, so a conversion step appears constantly in quick scripts, prototypes, and one-off data cleanup jobs. A converter in the browser is handy when you want a fast look without writing a one-liner in a terminal.
Use the tool
Get predictable JSON
Set the delimiter if your file is tab-separated or uses semicolons. Watch quotes and newlines inside fields—true CSV is trickier than it looks. If your CSV has a header row, make sure the tool treats the first line as keys when that is your intent. If the JSON is huge, be mindful of browser performance.
Type awareness
CSV is all strings until you choose types. If you need numbers, booleans, and dates, you may still need a follow-up step in code.
