xlsx

To convert Excel sheets to CSV safely, this skill extracts local XLSX data, applies PII and security checks, and exports the sanitized sheets as CSV or TSV files to a designated output directory.

Yes, you can extract data from large Excel files without exceeding token limits because the skill estimates token usage, enforces data sampling for large workbooks, and exports only the necessary sheet subsets.

The best way to inspect spreadsheet metadata is to generate an overview that lists sheet names, row counts, and estimated token usage, which allows you to plan an efficient extraction strategy before processing.

You can create a new XLSX file from CSV data by using the spreadsheet conversion feature, which reads your CSV headers and rows to generate a formatted workbook with auto column widths.

Yes, spreadsheet conversion supports existing workbooks by allowing you to edit specific cells and formulas, add new sheets with formatting, and apply auto column widths directly within the local XLSX file.

The main limitation of processing local Excel files is context size; to prevent accidental data leaks and processing failures, the skill enforces sampling for large files and restricts outputs to CSV or XLSX formats.
