What problem does it solve? Spreadsheet workbooks (.xlsx, .xls, .xlsm) cannot be clipped into a Markdown wiki by HTML or PDF clippers, and converting them to PDF first destroys the row-label pairings that give each number its meaning. This Skill extracts workbook content as faithful Markdown tables so the vault stays greppable, diffable, and citable. ## Core Features & Use Cases - Workbook-to-Markdown conversion: Pipes LibreOffice HTML rendering through pandoc to produce Markdown tables with standard clipping frontmatter (source, quality, source-hash, tags). - Content-hash deduplication: Detects renamed or moved workbooks already in the vault by hashing contents, preventing duplicate clippings under a second slug. - Batch-safe failure handling: Distinguishes a missing LibreOffice install (fatal, stops the run) from a corrupt or password-protected workbook (returns failed so batch runs continue). - Use Case: During a research run, clip a downloaded financial workbook with a topic tag so the triage step can group it with the rest of the run, then hand the clipping off to wiki-ingest for summarization and cross-referencing. ## Quick Start Ask the agent to clip the workbook at a given path into the wiki, optionally passing the source URL, quality tier, and research topic.
