I have an xlsx file which opens fine in MS Excel and in Google Drive.
When I open in LO, I get one empty sheet. No visible data.
I enclose an example file, so maybe you can reproduce.
When I open this file in GoogleDocs, and I save to LO-format ods. Then I can open it perfectly in LO.
In the sample file are 2 lines of data. 1 top row with column labels in bold. And 1 line of data.
I am using LO version: 126.96.36.199 (x64)
Build ID: 65905a128db06ba48db947242809d14d3f9a93fe
Thx for your advice.
