# UPPER Google Sheets Function [With Quiz]

**Updated:**August 24, 2021

In Google Sheets the UPPER function outputs the provided text with __all__ uppercase characters.

## UPPER Syntax

- text = the "text" or a cell reference to the text you want to convert to uppercase characters.

This function is useful for converting things that are usually uppercase (like acronyms) to a consistent format.

UPPER, in combination with functions like LEFT and RIGHT, can also be used to make part of some text uppercase.

## UPPER Function Example

A | B | C | |

1 | Text | Formula | Output |

2 | abc | =UPPER(A2) | ABC |

3 | kiss | =UPPER(A3) | KISS |

4 | Swag | =UPPER(A4) | SWAG |

5 | FnC | =UPPER(A5) | FNC |

6 | btb | =UPPER(A6) | BTB |

You can also reference text directly instead of using a cell reference:

Will output: ABC

## Using The UPPER Function On A Whole Column

By combining the UPPER function and the ArrayFormula function you can force UPPER to accept more than one argument.

This means you can make multiple cells uppercase, an entire column or row, or even a table with only one formula.

Here's an example using the same data as above:

A | B | C | |

1 | Text | Formula | Output |

2 | abc | =ArrayFormula(UPPER(A2:A6)) | ABC |

3 | kiss | KISS | |

4 | Swag | SWAG | |

5 | FnC | FNC | |

6 | btb | BTB |

All of the text is converted to uppercase characters using a single formula.

## UPPER Errors

The UPPER function is very stable, handling the following without error:

- Blank cells,
- Numbers (returning them as text), and
- Boolean data (returning them as uppercase text)

If you input a range (e.g. A2:A6) without using ArrayFormula it will output one piece of uppercase text if the range crosses the same row or column as the formula's cell.

Otherwise, it will throw a #VALUE! error:

An array value could not be found.
