Security Audit
Medium RiskMost static findings are Markdown code fences, documentation links, or local LibreOffice examples rather than hidden execution. The remaining risks are the troubleshooting commands that kill LibreOffice processes, open a localhost UNO socket, and reference one plain HTTP documentation URL.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Build Department Reports
Create recurring ODS reports with formulas, totals, formatting, and export steps for sharing.
Convert Client Files
Plan safe conversion between ODS, XLSX, CSV, and PDF formats while preserving source files.
Automate Spreadsheet Setup
Use UNO or ezodf examples to design repeatable spreadsheet creation and formula workflows.
Try These Prompts
Create an ODS spreadsheet plan for a monthly budget. Include income, expenses, totals, and clear formatting.
Convert an ODS file to XLSX and PDF. Explain the LibreOffice command steps and backup checks.
Design a Calc workbook for sales tracking. Include formulas, input validation, conditional formatting, and a summary sheet.
Plan a batch workflow that converts spreadsheets, validates results, logs failures, and avoids overwriting source files.
Best Practices
- Review shell commands before running them on real files.
- Keep source spreadsheets and backups before conversion.
- Use sample files to test formulas and exports first.
Avoid
- Running commands against broad file patterns without checking the directory.
- Opening a local automation socket longer than needed.
- Assuming format conversion preserves every formula or chart exactly.
