.ods ->.csv -> .ods
Font formatting: gone (bold, italic, underlined, color)
Border formats: gone
Color backgrounds: gone
Conditional formatting: gone
Column widths: gone
Cell merges: gone
Charts: gone
Multiple sheets: no, choose one at a time.

If people are already complaining about a few clicks to zoom pdfs, and they are, there's no way they'll tolerate the extra effort of importing and deciphering what it takes to re-create effective formatting.

Yes, and they can be launched without enabling-JavaScript/"Trust"-ing-"this"-document, which is probably why Adobe has discontinued Flash. But as you said it is a balancing act. Still, it seems unwise to enable extensions which are disabled by default in forum software.

Make a zip of what you (general you) want to attach, and that's it. Then the safety part, as well as responsibility of scanning, etc., will fall on the downloader, not on the forum.

I disagree. Restricting attack vectors should be enforced. Sure, one can upload virus.exe.zip but the mods can keep an eye on such zips. Macros hidden in spreadsheets, word processor documents and presentations taxes policing.

 2021-07-28, 08:50 #27 LaurV Romulan Interpreter     "name field" Jun 2011 Thailand 231118 Posts We mainly say the same thing, nothing to disagree about (unless I understand your post wrong, or you mine). As somebody here would say, we are in violent agreement. People requested more extensions to be allowed, and my question was "why?". What can't you attach, as long as zip was already permitted? Why should we lower the security by allowing docs and excel files, etc? Last fiddled with by LaurV on 2021-07-28 at 09:31

So you are a form over function man. Doesn't matter what it does as long as it looks pretty.

Just give me the data. If I want it to look pretty I will beautify it myself.

As for the complainants I have absolutely no sympathy for them. If they find that intolerable they weren't very interested in the information anyway.

But, at least for LibraOffice Calc under Fedora 34, I had to go to each cell and delete the equals sign and then insert it again before it became a calculated cell. Simply clicking on a cell, then clicking in the editing field and hitting enter didn't work.

No. Formatting promotes readability. It is the responsibility of a poster to communicate effectively. That is function.

Oh, and
header fields: gone (not just the formatting, the content too)
footer fields: gone (not just the formatting, the content too)
In some of my spreadsheets, background or font color encode/represent status or class of the exponent in the cell; formatting IS content there too.
(example: one color text means unassigned, another means in TF, another in P-1, another in primality test)
