Of course it does.
I should amend that: The CSV technique did not. The JSON technique does. In this case it doesn't matter, because the data formats are all known ahead of time. It's not generalized.

That is what I thought too. I had rolled my own JSON parser because the data was in a set format. Did not think I needed a whole big JSON library. Everything was humming along nicely until I was about 110,000 reads in, then the website threw in a different format and it all went boom. The fix was easy, but what a pain. I was glad I was the only one using the code.
Within you lies the power for good - Use it!

JSON is a bit different than CSV though. My JSON is compliant.

I rolled my own JSON reader -- converting JSON to XML as it goes, because SQL Server has an XML datatype and functions.
And every once in a while I would receive a corrupt JSON file (produced by a third-party product) and I would need to deal with it. In such cases I needed to report where the error occurred.

I derived my parser from this, ultimately: JSON[^]
Although I first converted a lot of it to regex for reasons.

Yep, I have referred to that many times. All I need to do is load data from JSON files into database tables. My reader scans along, tokenizing the JSON, and checking whether or not it has located an item I want to send to the database.

Yeah I do similar. I used my Visual FA project to render some state graphs, and then used those to hand roll a lexer/tokenizer in C++. I hand rolled it because even though I have a generator for C/C++ I do some extra things while lexing. Like when I'm scanning a number it parses the number into a double and a long long both at the same time. That way I get numeric values on those fields and I don't lose precision for very long ints. Since it streams it can process very long numbers, even though it will lose precision

Because I'm loading to SQL Server, I let the server do that as appropriate. I just send XML and extract individual values via XPath and squirt them into columns.

Mine is a generalized JSON parser. I use it for various things.

I also have not used an off-the-shelf JSON reader. I convert the JSON to XML; I do not need "objects". If I had "objects" I'd just have to serialize them to XML anyway and that's a waste of resources. Additionally, I don't need to have the whole dataset live in memory at one time.

Very neat. But let me hijack the discussion. 
How accurate are those IP-to-geographical location mappers?
I always laugh, when I'm playing an online game, and so-called "hackers" (who are typically too young to know anything about the original meaning of the word) "threaten" to reveal my physical address based on my IP. Apparently that makes me dumb for not using a VPN.
I always congratulate them for finding out what city my ISP operates from. Which is nearly 500km away from me.

It depends on your ISP. Obviously in your case it might be an issue, but it's usually accurate enough to get the time zone and regional weather and stuff.

I know the most fun thing about it is how many map to some location in the middle of nowhere.
The GPS coords for the geographical center of the US... Some farm in Kansas or something.
And if it doesn't know? That's the default. Anonymous is headquartered out of an old farm house in Kansas. Heh.

LOL!!! A lot of websites think they can locate me that way - even Google thinks I'm in Los Angeles (well, Hawthorne, at least). Not even close...

I have been using VS 2022 17.7.4 on my home box for a while.
A few weeks again I set up a VM and installed VS2022 17.9.6.
In 17.7.4, the region collapse/expand icons are plus/minus signs in a little box. Pretty clear to see and understand.
In 17.9.6, they use ^ and > sumbols, which, IMHO, is a lot harder for your eyes to figure out.
Why would they change this????

Personally, I don't mind it.
At first I thought it was a resharper or visual assist thing.

I do mind it. Not only do the new icons look horible, it's just the fact that they would change it. I mean, why???
This is the sort of thing that drives devs mad. Leave things alone!!! It wouldn't be so bad if they created an option to change it an defaulted it to the previous setting, but to just go about changing the UI that devs are used to with zero warning is just rediculous.

You missed it Kevin. He's poking at you. But seriously, changing defaults on developers is just an abortion. Dear MS, I have a really good elephanting idea. If you think what you are doing is better, let us have the option of "we disagree, make it go back".
The only thing worse I have ever seen MS do (maybe I'll make a website and had ads...) is force reboots. Whoever made the final decision on that needs to be beaten to the point of hospitalization (not the morgue). Free points if you can cite the movie.

I know, right? And then they do NOT actually fix what devs have been begging them to fix, such as:
Microsoft Developer Community - Full Git Submodule Support[^]
Look in the comments in the thread of that post and you'll see what I mean.
Look, it took them until VS2022 just to make the devenv.exe process a 64-bit process.
