How to Convert CSV to JSON
ToolPrime Team 2 min read
When you need to send spreadsheet data to a web API or use it in a JavaScript application, converting CSV to JSON is essential. Each row becomes a JSON object, and column headers become property keys.
1 Prepare your CSV
Make sure your CSV has a header row. Each column header becomes a JSON property name.
2 Paste into the converter
Open the CSV to JSON converter and paste your CSV data.
3 Get your JSON
The tool outputs a JSON array of objects. Copy or download the result.
How It Works
CSV to JSON conversion takes each header as a key name and each row as an object. The first row defines property names, and subsequent rows become array elements. Numeric values are typically preserved as numbers, not strings.
