Hi,
I am using MD 2024.4 (525) on MacOS 15.3.1 (24D70).
In France, we use coma for decimal and space for thousand.
In the General Preference box, I only found the separator (set to ,) but nothing for the thousand separator.

Unfortunately, MD display a point separator.
This is also true in the report.
The Copy button also copy the . with the tow "Tab delimited" option who are respecting the comma separator. This does not allow the easy paste in Excel (work around is to paste and then use convert of the Excel Data menu where we can set the decimal and thousand separators).

Reading the support page, I found it is an old issue (found discussions in 2010, 2013, 2022) and it looks not solved.
I found the configuration file (config-20250220-0906.dict_$SAVED$ but there is nothing about the thousand separator.
It looks you are mixing flexibility for users with decimal separator and internal chose for thousand separator.

I suggest 3 possibilities to solve this issue:
1) Uses the system setup (MacOs, Windows, Android, iOS) to found the user presentation request
2) Introduce the separator setup in the General Preference page (may be useful even if you apply solution 1)
3) Do not use thousand separator in the "Tap Separator for Excel" (like it is done in the coma separator option)
This should apply to pages view, reports and copied data.
It should also apply to mobile application to facilitate data reading and application coherence.

Is there anything I misunderstood?
Can you solve this issue?
