The converter handles standard tabular CSV data and converts it to flat JSON objects. For nested structures, you may need to post-process the JSON in your code.
The tool runs in your browser, so it can handle files up to several megabytes efficiently. For very large files (100MB+), consider using a command-line tool.
The converter outputs all values as strings by default, since CSV does not have type information. You can parse numbers and booleans in your application code after conversion.
