Xlsb file with dropdown list

Hi!

I downloaded xlsb file with dropdown list. I opened it in LibreOffice Calc but I don’t see dropdown lists. My Libreoffice version is 7.6.2.1, OS: win 10 pro. Is it exist extension pack or something like that to extense calc possibilites?

Let’s take a look at your file. Upload this file please.

Sure!

unfortunetly I can’t upload *.xlsb here.

The Zamzar ( https://www.zamzar.com/ ) can not convert the .xlsb files.
An another online conversion tool

can convert it. It is appeared two Named Cells, and appeared many dropdowns in the converted .xlsx file. Then I saved it into .ods format:
