Reference checked: Examples have not been run in this spreadsheet application. How we verify guides

The COLUMNS function in Apache OpenOffice Calc is used for this task: Returns the number of columns in an array or reference. Count the number of columns in a selected range.

This guide explains how to read the formula, reproduce a concrete example, interpret its result and recognize common input mistakes.

Syntax and arguments

The worked formula below shows the argument order used for this example. Consult the linked software-specific function reference for optional parameters and edge cases.

Apache OpenOffice Calc commonly uses semicolons (;) between function arguments. Confirm the separator in your installation.

Worked example

Use this small practice sheet for the ranges referenced in the formula:

Row A (Quantity) B (Amount) C (Category)
1 1 10 apple
2 2 20 pear
3 3 30 apple
4 4 40 pear
5 5 50 apple 
=COLUMNS(A1:C5)

Expected result: 3.

Why it works: Count the number of columns in a selected range. The specified sample table supplies the referenced cells.

How to use it in your own spreadsheet

  1. Identify the cells or inputs that correspond to the sample values above.
  2. Enter the formula in an empty cell, changing the references or literal values to match your sheet.
  3. Compare the output with a manual check on a small known example.
  4. Extend the formula to a larger dataset only after you understand the result.

Common problems and practical checks

  • Use the correct lookup column or return range, and use exact-match options where appropriate.
  • Check for duplicate keys, leading spaces and numbers stored as text in lookup data.
  • A pasted formula may produce an error when it uses the other program’s argument separator or unsupported options.
