CSV to JSON Converter

CSV and JSON are two of the most widely used data formats in software development, data science, and business analytics. CSV files are the standard export format for spreadsheets, databases, and reporting tools, while JSON is the backbone of web APIs and modern application data exchange. Our bidirectional converter lets you move data between these formats instantly, handling real-world complexities like quoted fields containing commas, escaped double quotes, and empty values that simpler tools often mishandle.

The tool gives you full control over parsing options. Choose your delimiter to work with comma-separated, tab-separated, semicolon-separated, or pipe-delimited files. Toggle whether the first row should be treated as column headers, which determines whether your JSON output is an array of objects with named keys or an array of arrays. The pretty print option formats JSON with proper indentation for readability, while minified output is ideal for use in API payloads or configuration files where file size matters.

Everything runs locally in your browser, so your data never leaves your machine. This makes it safe for converting sensitive business data, customer records, or proprietary datasets. Paste your CSV or JSON into the appropriate panel, click the conversion button, and copy the result with a single click. The tool also displays row and column counts for your CSV data, giving you a quick sanity check that your data was parsed correctly before you use it in your project.
