Question 1

How do I convert a CSV file to JSON?

Accepted Answer

Upload your CSV or Excel file and the tool instantly converts it to JSON format. Each row becomes a JSON object with column headers as keys. You can copy the result or download it as a .json file.

Question 2

What JSON format does the converter output?

Accepted Answer

The output is an array of objects, where each object represents one row. Keys are the column headers, and values are the cell contents. Numbers and booleans are auto-detected and converted to their JSON types.

Question 3

Can I convert CSV to nested JSON?

Accepted Answer

The tool produces flat JSON objects by default (one key per column). For nested structures, you would need to transform the output further. Column headers with dot notation (e.g., 'address.city') are kept as flat keys.

Question 4

Is the JSON output formatted or minified?

Accepted Answer

The output is pretty-printed with indentation by default for readability. This makes it easy to inspect and validate. The formatted JSON is valid and can be used directly in applications or APIs.
