Why isn't PERCENTILE.EXC working in LibreOffice?
PERCENTILE.EXC exists in LibreOffice 25.8.7.3, but it is not a drop-in match for
Excel — our executed tests found real behavioral differences (detailed in the test results on this
page). If a formula that works in Excel or Google Sheets misbehaves in LibreOffice, compare your usage
against the failing cases above before assuming your data is wrong.
Discovered quirks
- =PERCENTILE.EXC(A1:A10,0) on LibreOffice Calc returned #VALUE!, but the documented/expected result is #NUM!. MISMATCH vs expected: expected '#NUM!', got '#VALUE!'
- =PERCENTILE.EXC(A1:A10,1) on LibreOffice Calc returned #VALUE!, but the documented/expected result is #NUM!. MISMATCH vs expected: expected '#NUM!', got '#VALUE!'
Executed test cases
LibreOffice Calc 25.8.7.3 (tested 2026-08-06)
| Formula | Description | Result | Expected | Verdict |
|---|---|---|---|---|
| =PERCENTILE.EXC(A1:A10,0) | Documented divergence from PERCENTILE.INC: PERCENTILE.EXC requires k strictly between 0 and 1 (and more precisely between 1/(n+1) and n/(n+1)); k=0 -> #NUM!. Confirmed via Microsoft's PERCENTILE.EXC docs (https://support.microsoft.com/en-us/office/percentile-exc-function-bbaa7204-e9e1-4010-85bf-c31dc5dce4ba): "If k is <=0 or if k >=1, PERCENTILE.EXC returns the #NUM! error value." PERCENTILE.INC_k_zero on identical data returns 1, not an error. | #VALUE! | #NUM! | Mismatch |
| =PERCENTILE.EXC(A1:A10,1) | k=1 is likewise out of PERCENTILE.EXC's exclusive valid range -> #NUM!, whereas PERCENTILE.INC_k_one on identical data returns 10 | #VALUE! | #NUM! | Mismatch |
| =PERCENTILE.EXC(A1:A10,0.5) | k=0.5 is within the valid range for n=10 (1/11 < 0.5 < 10/11) and matches PERCENTILE.INC's result at the median | 5.5 | 5.5 | Matched |
| =PERCENTILE.EXC(A1:A10,0.1) | k=0.1 is valid since 1/(n+1)=1/11=0.0909 < 0.1 < 10/11=0.9091 for n=10 | 1.1 | 1.1 pos=k*(n+1)=0.1*11=1.1 -> interpolate 10% of the way from data[0]=1 to data[1]=2 -> 1.1 |
