=AVERAGEIF(range, criteria, [average_range])

Square brackets are documentation markers for optional parameters, not characters to type in a formula. Formula names and comma-separated arguments here follow ONLYOFFICE’s official function-entry guide. Locale settings can affect punctuation and displayed formats.

Create a new sheet with these small source records:

If a cell is marked leave empty, leave it truly empty rather than entering the words in the table. Put the formula in a free cell away from the source data.

=AVERAGEIF(A2:A6,"East",B2:B6)

Expected result: 80. East scores 90, 70 and 80 give (90+70+80)/3=80. This is an arithmetic/logical prediction on the supplied sample, not a claim of native ONLYOFFICE testing.

=AVERAGEIF(A2:A6,"West",B2:B6)

Expected result: 70. West scores 40 and 100 average 70. Comparing these two results helps identify incorrect ranges and mismatched conditions.

Average the numeric scores of 80 or greater without using the Region column.

=AVERAGEIF(B2:B6,">=80")

Expected result: 90. Qualifying scores 90, 100 and 80 average 90. Change just the source value described above to reproduce the variation.

AVERAGEIF without average_range averages the tested range. A missing or text-formatted score differs from a numeric zero; if no scores qualify, do not treat a zero as a valid average.

Unrecognized formula names, missing arguments, incorrect parentheses and incompatible separators may cause an error. When an output is surprising, test the small example first, check whether input values are genuine numbers, then inspect the formula’s range endpoints. Do not guess a specific error label when it has not been produced by a native test.

Use COUNTIF to check how many values match each criterion and inspect the numeric score cells before interpreting the mean. If formulas are displayed as text, ensure the destination cell is treated as a formula and starts with an equals sign. If copying a formula, decide which references should remain fixed and apply $ anchors as needed.

The current official function inventory lists this function. The checked changelog does not give its first supported build. Verify the installed edition rather than implying unsupported old builds work.

The official changelog was reviewed on 2026-10-11 UTC. No unsupported introduction date or minimum edition is invented.

AVERAGEIF exists in Excel and Google Sheets; check input type and argument-separator differences. Microsoft also provides a version-aware function catalogue. Consult the eight-software comparison for navigation, but verify formula semantics in each destination app before copying a workbook.
