INFO

This page was originally generated from official documentation.

Returns unique rows in the provided source range, discarding duplicates. Rows are returned in the order in which they first appear in the source range.

Syntax

UNIQUE(range, by_column, exactly_once)
PartDescription
rangeThe data to filter by unique entries.
by_columnWhether to filter the data by columns or by rows. By default, this is false.
exactly_onceWhether to return only entries with no duplicates. By default, this is false.

Notes

  • If rows are returned which appear to be duplicates, ensure that cells including text do not have differing hidden text such as trailing spaces.
  • Ensure that numeric values are formatted in the same way - percentages as percentages, currency values as currency values, etc.

Examples

Running UNIQUE on this input:

RedYellowRed
BlueMagentaBlue
RedYellowRed
GreenWhiteGreen

Yields:

RedYellowRed
BlueMagentaBlue
GreenWhiteGreen

And running UNIQUE with by_column set to true on that output yields:

RedYellow
BlueMagenta
GreenWhite

Finally, running UNIQUE with by_column set to false but exactly_once set to true on the original input yields:

BlueMagentaBlue
GreenWhiteGreen
