Description NISZ LibreOffice Team 2020-01-13 15:02:59 UTC
Description:
Attached simple XLSX file contains date formatted cells with the default locale-dependent Excel format in A2:A3.
After saving the file in Calc the date format changes to Custom “[$-409]h.n.éééé” ([$-409]m.d.yyyy in Excel 2013 using English locale and [$-40E]éééé.hh.nn ([$-40E]yyyy.mm.dd) using Hungarian locale.

Steps to Reproduce:
1. Open attached file in Calc and save it as XLSX.

Actual Results:
Excel does not recognize the cell format as Date, instead it lists it under Custom.

Expected Results:
Excel recognizes the cell format as Date – Locale-dependent default.


Reproducible: Always


User Profile Reset: No

For the record, I can reproduce it in

Version: 6.5.0.0.alpha0+
Build ID: fc1f85127968d1c2e0a53dace51bf8a78f9e6ca5
CPU threads: 4; OS: Linux 4.19; UI render: default; VCL: gtk3; 
Locale: en-US (en_US.UTF-8); UI-Language: en-US
Calc: threaded

and MSO Excel 2010

@Eike, would you mind taking a look ?
Comment 9 Eike Rathke 2020-03-15 16:14:44 UTC
This is an import failure that apparently always existed but had no consequences so far. Note that the date format here in LO becomes a fixed-locale format (e.g. English-US or Hungarian) and not a system locale format (e.g. Default English-US or Default Hungarian). Since the commit mentioned that is exported as such as it should.
