Why use Parquet over CSV for data warehouses?

Parquet is a columnar storage format that offers superior compression and query performance compared to row-based formats like CSV.

What happens to empty cells in my Excel file?

If 'Convert Empty to Null' is enabled, the tool automatically maps blank cells to null values, preventing schema errors during ingestion.

Can I export multiple sheets at once?

The tool processes one sheet at a time. You can specify the sheet name to target the exact data you need to export.

What does 'Sanitize Field Names' do?

It automatically cleans column headers by removing special characters and spaces, ensuring they meet strict naming conventions required by most SQL databases.

Is there a limit to the file size?

The tool supports files up to 100MB, which is sufficient for most standard analytical datasets.
