Description JohnR 2021-03-09 09:28:51 UTC
I have generated xlsx file using Open XML SDK structure and file is loaded blank. If you try to open it in Microsoft Excel it shows data, and if you just save it, it can be also read by LibreOffice. Seems like structure of generated XML is not readable by Libre, but im not sure.

Steps to Reproduce:
1. Open XLSX file

Actual Results:
Blank file

Expected Results:
Loaded file with 5 rows of data

Reproducible: Always

User Profile Reset: No

Additional Info:
I can send example of docs if needed.

according to Excel, some cell information needed repairing.

when I load the repaired file in LibreOffice, I can see the contents.

Comment 5 JohnR 2021-03-09 12:59:44 UTC
Yes, its repaired when open in Excel and save. But do you know what cell need reparation ?

I've loaded xlsx in OOXML viwer and difference is in app.xml auto generated by SDK where 

Difference in app.xml:
Repaired file:

    <vt:vector size="1" baseType="lpstr">


Original file:
    <vt:vector size="1" baseType="lpstr">


Other difference in SharedStrings.xml (self closing tag)

Comment 9 himajin100000 2021-03-09 18:40:39 UTC
just a guess (possible cause?)

case-sensitiveness of the filename "sheet1.xml" and "Sheet1.xml"
Comment 10 himajin100000 2021-03-09 19:08:13 UTC
possible source code pointer?

Comment 11 JohnR 2021-03-10 11:31:58 UTC
Yes thats the problem. Even if pointer in workbook is Sheet1 it can't be read unless its lower case.

Thank you for solving this issue!

Are we sure it's LO's problem?
Comment 13 JohnR 2021-03-11 12:32:50 UTC
After I've replaced xl/worksheets/Sheet1.xml to xl/worksheets/sheet1.xml content is loaded normal in Libre, even stylings and filters are displayed. Im not sure why there is check for LO, maybe some convention...

Yes it's related but the pb is LO uses one of these:
- [Content_Types].xml
- xl/_rels/workbook.xml.rels
Indeed, if you unzip the xlsx, you'll see:

So the simplest thing would be to fix Open-XML-SDK so it would be coherent and about this bugtracker, I would put NOTOURBUG/NOTABUG but just my opinion.

László: any thoughts here?

This looks similar to bug 100084.
