multi-file-excel-parquet-analysis

To count rows across multiple sheets in a large Excel file, this Skill reads each sheet individually and aggregates per-sheet row counts to estimate the total dataset size. It handles multi-sheet workbooks robustly for large-scale data analytics.

You can convert an Excel workbook to Parquet format to improve subsequent analysis performance and storage efficiency. This Skill directly ingests the Excel data and exports it as Parquet files for optimized downstream workflows.

Yes, you can generate a visualization report directly from Excel data. This Skill performs categorization, calculates statistics, and outputs downloadable statistical reports alongside charts for large Excel datasets.

Yes, this approach works for estimating dataset size before Parquet export. It enumerates every sheet to calculate total row counts, providing a clear estimate of data scale prior to format conversion and visualization.

The best way to handle categorization and percentage analysis for Excel data is using an end-to-end workflow. This Skill ingests the workbook, calculates category statistics, and generates a report with proportion analysis.

While robust input handling is implemented, limitations depend on the structure of the multi-sheet Excel files being read. Extremely complex or irregular sheets may affect the accuracy of row enumeration and subsequent Parquet conversion.
