Paste your CSV data into the input field or drag and drop a CSV file. Select the appropriate delimiter (comma, tab, semicolon, or pipe) and click Convert. The first row is treated as column headers by default — uncheck the box if your data has no headers. The JSON output can be copied or downloaded as a file.
This CSV to JSON converter handles quoted fields, escaped characters, and various delimiters. It works entirely in your browser — no data is sent to any server, keeping your data completely private. Use it for transforming spreadsheet exports, database dumps, API data preparation, and more.
