Drag and drop your CSV or TSV file directly into the drop zone, or paste your raw tabular text into the input box. The tool automatically detects your column delimiter (comma, semicolon, tab, or pipe), parses RFC 4180 quotes with escaped double-quotes, and outputs clean, structured JSON in real time. You can copy the generated JSON directly to your clipboard or download it as a ready-to-use .json file.
No. All parsing, validation, and conversion executes entirely within your browser using client-side JavaScript. Your CSV files, confidential records, and converted JSON outputs never cross the network, are never stored on external servers, and are never tracked in backend databases or analytics tools.
An array of objects maps each row in your spreadsheet to key-value pairs using the first row as property names, which is the standard format for modern REST APIs, MongoDB, and frontend components. An array of arrays converts each row into a flat list of cell values without repeating header keys, producing a significantly more compact JSON payload for large datasets.
When type inference is enabled, unquoted decimal numbers (e.g. 42 or 3.14), boolean keywords (true/false), and null tokens are converted into native JSON primitives. However, explicitly quoted values such as "123" or "true" are preserved as strings to protect zip codes, product SKUs, phone numbers, and identifier codes from unintended numeric coercion.
