It’s a way bigger pain in the ass than people think it is. I remember having to parse output from a tool for work that had tons of output in tabular format, mixed with normal sentence like strings. JSON, YAML, or XML outputs weren’t available so I had to do a nasty mess of grep, awk, cut, and head/tail, to get what I wanted. My first attempt was literally counting the characters so I could cut out exactly what I needed, but as we all know, hardcoding values is a recipe for headaches later on.
Here’s a horror story from literally yesterday. We have been fighting a system for a client for weeks and it has been a nightmare. Our clients just told us that they outsourced some of their work to an Indian outfit but that outfit is unfamiliar with Linux and doesn’t know how to edit text files so they have been downloading the files to their Windows machines, editing them in Windows, then uploading the contaminated text files back into Linux. None of them, not our client nor the outfit they hired, understood why this was a problem. We have no idea what files are affected and we won’t know until they fail because they obviously did not keep track of what they touched.
I will never forgive excel for automatically converting all of my dates to some weird ass format, or stripping single quotes randomly, or something other BS that they do for no reason
My absolute favourite is stripping leading zeroes from any text that looks like a number, then displaying it in scientific notation. But we get Copilot, so it balances out, right?
Does windows add an extra character at the end that gets converted to new line on linux? Because the other day I were copying a script and after pasting it an extra line was added after every single line, even the empty lines.

EDIT: I’m being intentionally vague.
Haha this is up there with having to explain why opening a csv in Excel and then saving means that I don’t want the file.

If this is about line endings, surely a simple shell or python script could correct them?
There’s already a command for it:

how it looked when I copied it:
what it turned into:
Windows uses CR LF (carriage return, line feed), whereas Unix just uses LF. For added fun, macs use CR.
This used to be true, for sure, but I thought this changed with OS X (which is essentially PrettyBSD) ?
You’re right. Notepad++ still lists macs as using CR for their EOL conversion tool, so I didn’t realize.
The only reasonable response to this behavior is disproportionate violence
You can just grep for carriage returns followed by newlines,
grep -Pirn '\r\n$' /path/to/whatever. It’ll identify all your problematic files.
