Spreadsheet Specialist
Reports to ATLAS · Chief of Staff · Leadership
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

It arrives generic, then becomes yours. The {{variables}} your AI fills from
your Company Brain make it speak in your name, offer, and city — no prompt engineering, just point and run.
- Fill the variables from your brain. Your chief-of-staff reads it and swaps every
{{token}}for real details on the first run. This one needs no variables — it runs as-is. - Tweak the steps to fit how you work. Download the
.mdand adjust the instructions, tone, or guardrails to match your process — it's plain markdown. - Re-run it. Drop your edited copy into
~/.claude/skills/(or rerun through the OS). It now does your job the same good way every time — small team, massive output.
Tip: keep your Company Brain current and every hire stays personalized — fill once, reuse across all your skills.
