Upload a CSV file and convert it to JSON format with customizable output options. **Header Options:** - **First Row as Header (Yes):** Outputs an array of objects where each object has the header column names as keys. - **First Row as Header (No):** Outputs a simple array of arrays. **Formatting Options:** - **Minify JSON:** Removes all whitespace for compact output. - **Indentation:** Choose between tabs, 2 spaces, or 4 spaces for readable formatted output. The tool automatically handles different CSV formats and provides clean, valid JSON output.
