What problem does it solve? Reading data out of local Excel (.xlsx/.xlsm) workbooks usually requires opening a spreadsheet application or writing ad-hoc parsing code. This Skill turns workbook inspection into a repeatable command-line operation that returns structured JSON or readable text, with no credentials or cloud services involved. ## Core Features & Use Cases - Sheet Listing: Enumerate every worksheet in a workbook with its row and column counts. - Structured Row Extraction: Read a single sheet as a JSON 2D array with empty rows skipped, trailing blank cells trimmed, and dates returned as ISO strings. - Full Workbook Dump: Convert an entire workbook into pipe-delimited readable text, either inline or saved to a file. - Use Case: Download an .xlsx report from Google Drive, then run the dump action to get the full contents as text you can search, diff, or feed into another pipeline. ## Quick Start Ask the assistant to read the sheet named Data from the local file report.xlsx and return the rows as JSON.
