Convert Excel and CSV to JSON Arrays

Comma-Separated Values (CSV) files are the standard format for exporting spreadsheet data from Excel, Google Sheets, and databases. However, integrating this flat data into modern web applications requires it to be formatted as JSON.

Our CSV to JSON Converter intelligently reads your CSV rows, uses the first line as the object keys (headers), and transforms the subsequent rows into a structured JSON array of objects. It fully supports standard CSV quoting, meaning commas inside quoted cells will not break the layout.

Preguntas frecuentes

Yes. The first row of your CSV must contain the column names. These names will be used as the keys for every JSON object generated.

As long as the cell containing the comma is enclosed in double quotes (which is standard CSV behavior), the converter will safely ignore the comma and keep the sentence intact.

This tool runs inside the browser memory. It works instantly for small to medium datasets (up to a few megabytes). For multi-gigabyte CSV files, a backend processing script is recommended.
