Set the workbook to recalculate automatically for iterative changes. Turn on recalculation so that formulas update on change and every minute, and enable iterative calculation with a maximum of 50 iterations and a 0.001 convergence threshold to allow the cash-flow circular reference to converge. Confirm that volatile functions like RAND and NOW update on that schedule and report any formulas that now risk slow performance.

sheets slowed to a crawl after a change

After I copied an auxiliary sheet into the model, the whole workbook started lagging and recalculation spikes CPU. I’m worried I’ve introduced many volatile formulas or accidental circular references. I can list the recent sheet copy and the cells I edited. What’s the likely cause and the fastest diagnostic steps to restore interactive performance without losing recent edits?

we keep getting slow workbooks from feature copies

Every time an analyst copies a template or adds a scenario sheet, the file becomes sluggish because someone sprinkles volatile formulas and circular math. I’m the ops lead with many contributors. Which concrete rules, review checklist, and editor habits should I enforce so models stay responsive while still allowing iterative calculations where truly needed?

Every task here came from the work, not from a feature list — which is why the prompts name what you want done and never the button that does it. The tool changes; the work does not.
