Use case

IF formula generator for spreadsheet work.

Translate a business rule into IF logic that can be pasted into Excel or Sheets.

What this page gives you

  • A draft IF formula for the rule and output labels you provide.
  • A breakdown of true, false, and blank-cell branches.
  • Checks for boundary values and nested-logic readability.

When to use it

Use this page for status labels, thresholds, and simple branching rules where the formula should return one text value or another.

Do not force a long decision tree into deeply nested IF statements if the rule has many branches. IFS, SWITCH, or a lookup table may be easier to audit.

Worked example

For customer names in A and revenue in B, an IF formula can flag high-revenue rows while handling blanks.

=IF(A2="","Missing",IF(B2>1000,"Review","OK"))

The formula returns Missing for blank customer names, Review for revenue above 1000, and OK for the remaining rows.

Check before you paste

  • Check text labels for exact spelling and capitalization.
  • Test boundary values such as exactly 1000 when using greater-than logic.
  • Consider IFS or SWITCH when the rule has many branches.
