Frequently Asked Questions
How do I convert CSV to JSON?
Paste your CSV text (or upload a .csv file) into the editor. GoodParse reads the first row as column headers and converts each subsequent row into a JSON object. The result is a JSON array ready for use in APIs or applications.
What delimiters are supported?
The converter supports comma (,), semicolon (;), tab (\t), and pipe (|) delimiters. It auto-detects the delimiter based on your input.
How are quoted fields handled?
Fields wrapped in double quotes are handled correctly, including quoted fields that contain commas. For example: 'Alice, Bob', '30' correctly becomes one field 'Alice, Bob' and one field '30'.
Can I convert Excel data to JSON?
Yes. Copy your Excel rows and paste them as tab-separated values. Or save your Excel file as CSV first, then paste the CSV content into the converter.
How does the tool handle missing values?
Empty fields in the CSV are safely converted to empty strings or null properties in JSON, preserving the object structure consistently.
Is this secure?
Yes, our converter runs locally inside your browser tab without making API calls. Your sensitive CSV data is never uploaded.
Seamlessly Transform CSV Data into JSON
CSV (Comma-Separated Values) remains the universal language for spreadsheet software, database exports, and legacy data systems. However, for modern web and mobile applications, CSV is incredibly difficult to parse and use directly. Applications require JSON (JavaScript Object Notation) to feed data into frontend components, APIs, and NoSQL databases like MongoDB.
Our CSV to JSON Converter bridges the gap between legacy data and modern tech stacks. By simply pasting or uploading a CSV file, our tool instantly maps the first row as object keys (headers) and converts all subsequent rows into a cleanly formatted JSON array of objects.
