How to Convert CSV to JSON

Converting spreadsheet data into a format suitable for web applications and APIs is a common task for developers. Our CSV to JSON converter simplifies this process by instantly transforming your Comma-Separated Values into JavaScript Object Notation.

Simply paste your CSV data into the input box, or upload a `.csv` file. The tool automatically detects your delimiter (comma, tab, semicolon, or pipe) and generates the corresponding JSON in real-time. You can choose to treat the first row as object keys (headers) or output a simple array of arrays.

Smart Parsing

Our robust parser handles complex CSV structures, including values wrapped in quotes and cells containing line breaks or commas, ensuring your data is converted accurately.

Auto-Detection

Not sure what delimiter your file uses? The tool automatically scans your data to detect whether it's separated by commas, tabs, semicolons, or pipes.

Flexible Output

Toggle between generating an array of objects (using the first row as keys) or an array of arrays. You can also minify the output to save space.

100% Private

Your data never leaves your device. The entire conversion process happens locally in your browser using JavaScript, ensuring maximum privacy and security.
