Claude skills for Spreadsheets & Templates.

3 skills built for spreadsheets & templates workflows. Each one installs in a single command and works in Claude and ChatGPT.

If you've ever spent a Sunday afternoon wrestling with ARRAYFORMULA logic or trying to get a conditional formatting rule to actually fire correctly, this category is for you. Spreadsheets & Templates skills give Claude a precise, working knowledge of spreadsheet structure — formulas, data validation, chart setup, and layout — so you can describe what you want and get back something that works in Google Sheets or Excel without the usual back-and-forth debugging. Right now there's 1 skill live in this category, with more on the way.

The current skill is squarely aimed at lifters and runners who track their training: the Fitness Tracker Spreadsheet with PR Auto-Detect builds you a fully functional Google Sheets training log with personal-record detection baked into the formulas, weekly volume summaries, and charts that actually update as you log sessions. Instead of downloading some generic template and spending two hours adapting it, you describe your training style and walk away with a sheet that fits how you actually train.

Frequently asked about Spreadsheets & Templates

Can I use these spreadsheet skills in ChatGPT or only Claude?
Skills on Skill Tree are built and optimized for Claude, so that's where you'll get the best results. The Fitness Tracker Spreadsheet with PR Auto-Detect, for example, is tuned to have Claude ask the right clarifying questions about your lifts and then output clean, copy-paste-ready Google Sheets formulas — that prompt structure is Claude-specific.
Do I need to know Google Sheets formulas to use these skills?
No. The whole point is that you don't have to. With the Fitness Tracker Spreadsheet with PR Auto-Detect, you tell Claude what you track — exercises, sets, reps, weight, distance, whatever — and it writes the ARRAYFORMULA, MAX, and conditional formatting logic for you. You paste it in, and it works.
Which skill should I start with if I lift weights and want to track PRs automatically?
Start with Fitness Tracker Spreadsheet with PR Auto-Detect. It's built specifically for that use case — it sets up a lifting log in Google Sheets where PR detection happens automatically as you enter new sessions, so you're not manually scanning old rows to see if you hit a new best.
Can the Fitness Tracker Spreadsheet skill handle running and cardio, or is it just for lifting?
Both. The skill covers lifting (sets/reps/weight) and running or cardio (distance, pace, time). When you start the skill, Claude asks what you actually track so the sheet it builds matches your training, not some generic template.
