What Is CSV to JSON?
Convert CSV data with headers into a JSON array of objects instantly.
CSV (Comma-Separated Values) files are the most common format for tabular data export from spreadsheets, databases, and business tools like Salesforce, HubSpot, and Shopify. But modern web applications and APIs use JSON as their native data format. Converting CSV to JSON is a required step whenever you import spreadsheet data into a JavaScript application, build a data visualization, or feed data into a REST API.
This tool treats the first row as field names (headers) and converts each subsequent row into a JSON object. The result is a properly structured JSON array, ready to paste into your code or POST to an API endpoint. Paste your CSV with a header row on the first line for best results.
