What is an unpivot operation?

An unpivot operation takes data organized in wide columns and rotates it into a long, vertical format, making it easier to filter and aggregate.

Can I keep specific columns unchanged?

Yes, you can specify ID columns that will be preserved as-is for every row generated during the unpivot process.

What output formats are supported?

You can export your normalized data as either an XLSX file or a JSON file, depending on your downstream requirements.

Does the tool handle empty cells?

Yes, you can enable the 'Drop Empty Values' option to automatically exclude rows where the value is blank, keeping your dataset clean.

Is there a limit to the file size?

The tool supports Excel files up to 100MB, ensuring you can process large datasets efficiently.
