FAQ

What is JSON?

JSON (JavaScript Object Notation) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications.

How are headers handled?

The tool assumes the first row of your Excel sheet contains the headers. These headers become the keys (property names) in the resulting JSON objects.

Is the output minified or pretty-printed?

The output JSON is "pretty-printed" with indentation to make it readable for humans.
