How It Works

Here's the secret sauce: The tool takes your CSV file, splits it into rows, and maps each row to a JSON object. The first row (your headers) becomes the keys, and the rest of the rows turn into values. These JSON objects are then combined into a JSON Lines format, where each line is a separate JSON object. It’s like turning a spreadsheet into a stack of index cards—easy to read, easy to use.
