Calculation steps

See precisely how a formula is evaluated. Step by step intermediate values, active branches, variable assignments, and resolved targets for lookup functions.

Work through complex formulas without leaving your sheet — open Calculation Steps and follow the evaluation as it unfolds.

Press Ctrl+Q to launch. Watch values resolve step by step, see which branches of IF/IFS/CHOOSE are taken, and view the exact ranges used by VLOOKUP, INDEX, INDIRECT, and more.

Navigate with the arrow keys: / expand or collapse nested layers, / jump to referenced cells. On very large files, enable Sandbox Sheet Evaluation in Settings → Formula Evaluation for consistently smooth performance.
