Run descriptive statistics on investigation durations: calculate mean, median, standard deviation and 90th percentile of days-to-close for closed cases and show a histogram and a moving average line to spot bottlenecks.

Before proposing process fixes, make the stats actionable: compute mean, median, std dev, 75th and 90th percentiles and a control chart of days-to-close by week, segment results by Investigator and Business Unit, and add annotations where durations exceed SLA for root-cause follow-up.

Formulas

Formulas in Excel perform calculations and operations on data within your worksheets.

  1. 1

    Select the empty cell where you want to enter the formula.

  2. 2

    Type an equal sign (=) to indicate the start of a formula.

    NoteThis tells Excel you are entering a calculation, not just text.

  3. 3

    Type the constants and operators, or a built-in function, for your calculation.

    Best practiceFor simple math, use operators like + (addition), - (subtraction), * (multiplication), and / (division).

  4. 4

    Press Enter (Windows) or Return (Mac) to complete the formula.

  5. 5

    To quickly apply the same formula to a range, select the range.

  6. 6

    Type the formula, then press Ctrl+Enter to fill the range.

  7. 7

    To evaluate a nested formula, select the cell containing the formula.

  8. 8

    On the Formulas tab, in the Formula Auditing group, select Evaluate Formula.

  9. 9

    Select Evaluate to examine each step of the formula.

  10. 10

    On the Formulas tab, click Calculation Options.

  11. 11

    Ensure that Automatic is selected for automatic recalculation.

    CautionIf not set to Automatic, formulas may not update immediately after data changes.

Use the Formulas tab to access tools for auditing, evaluating, and managing your formulas.

Formulas can be automated and generated programmatically using Excel's object model in VBA or through external libraries for languages like Python.

Questions people ask

honest answers

Because you rarely think 'I want the redaction tool'. You think 'I have to share this without leaking the client's details'. Start from the need, and the feature finds you.

Real. Every job here was drawn from what people in real roles were actually seen doing in Excel — not a feature checklist.

No. Each page gives you a ready prompt you can paste into an AI assistant, plus the plain steps to do it yourself. Start with either — the goal is the finished job, not the tool.
