NA Function (LibreOffice Calc)

• Returns the #N/A error
• Used to mark missing or unavailable data
• Helps distinguish “not found” from other error types
• Works with formulas, references, and conditional logic

It is designed to be simple, explicit, and semantically meaningful.

NA()

Arguments

• None.

Return the #N/A error

=NA()

Use NA to mark missing data

=IF(A1=""; NA(); A1)

Use NA in charts to skip points

=IF(A1=0; NA(); A1)

Charts ignore #N/A values.

Use NA to indicate lookup failure manually

=IF(B1=""; NA(); B1)

Use NA with MATCH to signal missing values

=IF(ISNA(MATCH(A1; B1:B10; 0)); NA(); MATCH(A1; B1:B10; 0))

Use NA in array formulas to skip invalid entries

=IF(A1:A10<0; NA(); A1:A10)

Use NA to prevent accidental calculations

=IF(A1=""; NA(); A1 * 2)

Use NA for debugging

=IF(A1>100; NA(); A1)

Use NA to force conditional formatting

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

Use NA to mark incomplete rows

=IF(COUNTA(A1:C1)<3; NA(); "OK")

NA always returns #N/A

=NA()

No arguments allowed.

NA is distinct from other errors

• #N/A means “not found” or “missing”
• Other errors indicate invalid formulas or references

Charts ignore #N/A values

This makes NA ideal for skipping points.

NA is caught by ISNA, ISERROR, and ISERR differently

• ISNA → TRUE
• ISERR → FALSE
• ISERROR → TRUE

NA is not text, not numeric, not blank

=TYPE(NA()) → 16 (error)

NA is useful for placeholder logic

Better than empty strings when you need explicit missing‑data signaling.

• Use NA to explicitly mark missing or unavailable data
• Use NA in charts to skip invalid points
• Use NA with MATCH and VLOOKUP for lookup workflows
• Use ISNA to detect NA values cleanly
• Avoid using NA when you want a blank cell — use "" instead

• Use ISNA to detect #N/A
• Use IFNA to handle #N/A gracefully
• Use ISERROR for broad error detection
• Use "" for visually blank cells
• Use IF to build missing‑data logic

By mastering NA and its companion functions, you can build clear, explicit, and error‑aware spreadsheets in LibreOffice Calc.
