IF Function (LibreOffice Calc)

Logical Beginner LibreOffice Calc Introduced in LibreOffice 3.0
logical conditions branching decision-making

The IF function in LibreOffice Calc evaluates a condition and returns one value if the condition is TRUE and another value if it is FALSE. Learn syntax, examples, common errors, and best practices.

What the IF Function Does â–¾

  • Evaluates a logical condition
  • Returns one value when the condition is TRUE
  • Returns another value when the condition is FALSE
  • Works with numbers, text, dates, and formulas
  • Can be nested to handle multiple conditions
  • Combines with AND, OR, and NOT for complex logic
  • Integrates with error-handling functions like IFERROR and IFNA

It is designed to be flexible, readable, and compatible across major spreadsheet applications.

Syntax â–¾

IF(test; value_if_true; value_if_false)
LibreOffice Calc uses semicolons (;) to separate arguments, not commas.

Arguments

  • test:
    A logical expression that evaluates to TRUE or FALSE (for example, A1 > 10, B2 = "Yes", C3 <> 0).

  • value_if_true:
    The value, text, or formula returned when test evaluates to TRUE.

  • value_if_false:
    The value, text, or formula returned when test evaluates to FALSE.

If you copy formulas from Excel or online sources that use commas, replace commas with semicolons to avoid Err:508 or Err:509.

Basic Examples â–¾

Return text based on a numeric condition

=IF(A1 > 50; "Pass"; "Fail")

Return numbers based on a text condition

=IF(B2 = "Yes"; 1; 0)

Use IF with cell references and arithmetic

=IF(C5 <= D5; D5 - C5; 0)

Use IF with text comparisons

=IF(E1 = "North"; "Region A"; "Region B")
Text comparisons in LibreOffice Calc are case-insensitive by default.

Advanced Examples â–¾

Nested IF statements (multi-level grading)

=IF(A1 >= 90; "A"; IF(A1 >= 80; "B"; IF(A1 >= 70; "C"; IF(A1 >= 60; "D"; "F"))))

IF with AND (multiple conditions must be TRUE)

=IF(AND(A1 >= 18; B1 = "Yes"); "Eligible"; "Not Eligible")

IF with OR (at least one condition must be TRUE)

=IF(OR(C1 = "Gold"; C1 = "Platinum"); "Priority"; "Standard")

IF with calculations (tiered discount)

=IF(A1 > 1000; A1 * 0.10; A1 * 0.05)

IF to check for blanks

=IF(A1 = ""; "Missing"; "OK")

IF with error handling using IFERROR

=IFERROR(A1 / B1; "Division Error")

IF with concatenated text output

=IF(A1 > 0; "Profit: " & A1; "Loss: " & A1)

Combining IF with Other Functions â–¾

IF with SUM and AVERAGE

=IF(AVERAGE(A1:A10) > 50; SUM(B1:B10); 0)

IF with COUNTIF (conditional messages)

=IF(COUNTIF(A1:A100; ">100") > 0; "Values over 100 found"; "All values ≤ 100")

IF with DATE comparisons

=IF(A1 < TODAY(); "Past"; "Today or Future")

Common Errors and Fixes â–¾

Err:508 — Missing parenthesis

Usually caused by:

  • A missing closing ) in nested IF formulas
  • Copying formulas that use commas instead of semicolons

Err:509 — Missing operator

Occurs when:

  • A comparison operator is missing
  • A nested IF is broken by missing separators or operators

IF returns the wrong branch

Possible causes:

  • Numbers stored as text
  • Text values with trailing spaces
  • Incorrect comparison operators

IF always returns FALSE

Often caused by:

  • Comparing text to numbers
  • Hidden characters in text cells
  • Using the wrong operator

Best Practices â–¾

  • Keep logical tests simple and readable
  • Use AND and OR to avoid deeply nested IFs
  • Use helper columns for complex logic
  • Wrap risky expressions with IFERROR or IFNA
  • Document complex logic with comments or notes
When formulas become too complex, split logic into multiple cells. This improves readability and reduces errors.
