Frequently Asked Questions

What format does CSV to JSON output?

Structra converts your CSV to a JSON array of objects, where each object represents one row, and the keys are your column headers. This is the standard format for APIs and JavaScript applications.

How do I handle a CSV with commas inside fields when converting to JSON?

Structra's parser correctly handles quoted fields with embedded commas. Your JSON output will have clean string values without the surrounding quotes.
