CSV to JSON

CSV to JSON Overview

Convert CSV data to JSON format

The CSV to JSON Converter enables you to import spreadsheet data into your web applications easily. It takes standard CSV text (likely exported from Excel) and converts it into a clean JSON array of objects. It automatically uses the first row of your CSV as the "Keys" (Types) for the JSON objects. It is smart enough to detect numbers and booleans, converting them to their proper data types instead of leaving them as strings. This is a massive time-saver for developers seeding databases or migrating legacy data.
