CSV to JSON Converter

Convert CSV to JSON format

What is CSV to JSON Converter?

The CSV to JSON Converter is a free online tool that transforms comma-separated values (CSV) data into a structured JSON array instantly in your browser, making it easy to import spreadsheet data into web applications, APIs, and databases. CSV is the most common export format from Excel, Google Sheets, and database tools, but most modern web applications and APIs work with JSON. Converting CSV to JSON manually requires writing parsing code or using complex formulas. This tool handles it automatically — it reads the first row as column headers, maps each subsequent row to a JSON object, and automatically detects data types for numbers and booleans. The result is a clean JSON array ready to use in your application, API, or data pipeline without any additional processing.
