CSV to JSON Converter
Convert CSV or tab-separated data into a JSON array. Auto-detects delimiters and supports key-value or flat-array modes.
CSV is everywhere — exported from spreadsheets, dumped from databases, generated by analytics tools. But modern APIs and front-end frameworks speak JSON. Manually converting CSV to JSON by hand is tedious and error-prone, especially when the data contains commas inside quoted fields, newlines in cells, or thousands of rows.
This tool parses your CSV input in the browser and produces clean JSON output instantly. It auto-detects whether your data uses commas, tabs, or semicolons as delimiters — useful when working with European locale spreadsheets that default to semicolons. Choose "First row as keys" mode to produce an array of objects keyed by the header row, or "Plain array" mode for a simple 2D array of values.
