Limits

The open-source component does not enforce a fixed max file size or max row count. Parsing and preview run in the user's browser, so memory and CPU on that device are the real limits.

Preview renders the first 100 rows while counts reflect the full file. Prefer reasonable customer uploads (thousands of rows, not multi-hundred-MB workbooks) and fail clearly in your own product copy if you need a business-level cap.
