Created attachment 118375 [details] Test.ods Hello, I think, that is bug in save to xls format. Formulas in odt format works for many saves SUMIFS(C:C;A:A;$E$1;B:B;$E$2) first save to xls SUMIFS(C$1:C$983040;A$1:A$983040;$E$1;B$1:B$983040;$E$2) second save xls to xls SUMIFS(#REF!$#REF!:#REF!$#REF!;#REF!$#REF!:#REF!$#REF!;$E$1;#REF!$#REF!:#REF!$#REF!;$E$2) Files in attachment (Test.ods, Test-1.xls, Test-2.xls) I think that problem: A:A => save to xls convert formula => A$1:A$983040 => save to xls convert formula => #REF!$#REF!:#REF!$#REF!
