Spreadsheet Triage Checklist
Built a small free thing this week: a "Spreadsheet Triage Checklist" — 7 common ways ad-hoc spreadsheets quietly break (stale copies, silent formula errors, no version control, etc.) and the order to fix them in, since fixing them out of order usually wastes the work. Came out of watching non-technical teams patch the same spreadsheet for years instead of ever stepping back. Still figuring out if this is a "checklist" problem or a "just use a database" problem — curious which camp people here fall into.
