Frequently Asked Questions

How does the CSV to JSON converter handle the header row?

The first row is treated as the header and becomes the key names in each JSON object. Subsequent rows become the values. Every row produces one object in the output JSON array.

What delimiters are supported?

Comma, semicolon, and tab delimiters are all supported. The tool auto-detects the most likely delimiter, or you can specify it manually.

What happens with missing or empty fields?

Empty cells produce empty string values in the JSON output. No field is dropped — every header key appears in every object to preserve consistent structure.
