FAQ
How are nested JSON objects handled?
Automatically flattened with dot-separated column names (e.g., user.name, user.email). You can also keep nesting or use custom separators.
What file sizes are supported?
Online version supports up to 100MB files with streaming. Enterprise version supports up to 10GB files, handling hundreds of millions of records.
Will data be lost during conversion?
No. All data is preserved completely. Arrays are expanded to multiple rows or columns in CSV, and original data types are maintained in JSON.
What encoding formats are supported?
Supports UTF-8, UTF-16, GBK, GB2312, ISO-8859-1 and other major encodings with automatic detection.
Can I batch convert multiple files?
Yes. Upload multiple files for batch conversion, with ZIP archive upload/download support for large-scale data processing.
