Frequently Asked Questions

How does the tool handle Unicode in SQL Server?▼

When the SQL Server Unicode option is enabled (default), all string literals are prefixed with N — for example N'value'. This ensures Unicode characters are preserved correctly in NVARCHAR columns.

What is the maximum batch size for SQL Server?▼

SQL Server supports up to 1,000 rows per INSERT statement. The tool defaults to 500 rows per batch to stay within this limit with safety margin.

Does this tool upload my data?▼

No. All parsing and SQL generation runs in your browser. Your data never leaves your machine.
