FAQ

Is the delimiter detected automatically?

You can control parsing with comma, semicolon, or tab options.

How are quoted fields handled?

RFC-like quoted escapes are supported. If you see an error, check the delimiter setting.

What if a large CSV freezes the page?

Browsers have limited memory; split the file into parts or use a server-side tool.

What this tool does

CSV ↔ JSON conversion bridges spreadsheets and APIs. CodeGrid Tools parses locally; datasets are not retained server-side. UTF-8 and delimiter settings matter for Turkish text. Data-tool quotas and Pro apply.
