I failed to predict this one...new csv format
-
It sounds like the columns of the rows are being put together in a string variable and the string writing function is wrapping the entire string in double quotes?

That was my guess as well. It could have been easily handled by the other programmer...he knew it was a problem, hence the phone call to me stating that my import isn't working properly with their new file format. :sigh: C'mon man, the thing won't even open properly in Excel! :laugh:

I think that's more of an ISV file, or Idiot Separated Value file.
What do you get when you cross a joke with a rhetorical question? The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism. Do questions with multiple question marks annoy you???

:thumbsup: But here, we take what we can get, which is why it became my problem...add function isTheWholeFrigginLineDoubleQuoted to set a Boolean PleaseRemoveTheFrigginDoubleQuotesOnlyAtTheBeginningAndEndOfThisLine which when true will perform the needed action. (who says you can't have self-documenting code!) :laugh:

Yeah - I think at this stage I have seen every type of craziness in CSV files - including columns containing the separator in the data with no quotes at all.

I've been importing from text files, spreadsheets, etc. for over 18 years now. Just when you think you've seen it all a client brings you this: Each line of a *.csv file starts and ends with double-quotes. :omg: Oh yes, we've had handling in place for many years to deal with embedded double-quotes in csv files (generally a sign of formatted numbers)...basically by stripping the formatting between pairs of double-quotes. It's worked great for many years until now...where it unfortunately removed all the commas leaving a big mess...not good!

I must be getting too old to argue, instantly agreed that it was my problem, fixed, tested, signed, sealed and delivered in < 30 minutes. Jpb security I guess! :laugh:

This sounds a lot like an issue that I encountered about 3 years ago, which gave rise to the [GitHub - txwizard/AnyCSV: Parse ANY CSV String, even X.509 Digital Signature Fields!](https://github.com/txwizard/AnyCSV) library for the Microsoft .NET Framework, about which I wrote two years ago, in [A Robust CSV Reader](https://www.codeproject.com/Tips/987455/A-Robust-CSV-Reader). The library is also available as a NuGet package, at [NuGet Gallery | WizardWrx.AnyCSV 4.0.106.27625](https://www.nuget.org/packages/WizardWrx.AnyCSV/).

There is no standard for "CSV" other than the de facto standard of "whatever Excel will open". Some of the "CSV"s I get have multiple headers and tables.
There is no standard for "CSV". Yes, there is: Common Format and MIME Type for CSV Files[^]. (Admittedly, its a bit of a post facto standard)

That is not a standard for CSV outside of a very limited domain.

:thumbsup: I'd send this to my client, but it's already been 'fixed'. btw, I actually saw firsthand how the problematic file (each line is enclosed in double-quotes) is being generated...via a SSRS report having all the values in a single column. :sigh: The real world standard for CSV = 'It opens fine with Excel'. :laugh:

If it won't open in Excel, its because Microsoft didn't plan accordingly. Isn't that the general thought process? Microsoft should account for everything?

Wait, what? Quoted text is supposed to be string data, particularly when there are commas in it, not a way of saying 'it's a number, Jim, but not as we know it'. They are really killing that CSV format. I feel your pain.

Yes, sorry I misquoted! :laugh: Yes, what I meant to say was that we apply special treatment to quoted fields/text where a number is expected but never expected each line to be double-quoted. It basically caused my parsing routine to behave in an unexpected way...not too difficult to fix once you see it coming. :)

Nothing is more annoying than a "programmer" who can't program or do simple calculations. I would have done the same thing. Arguing with these 'dips' is like talking to a wall. Just fix the darn thing and move on. What sucks even more is when you have to pay them and they send you a word invoice. Like have you heard of technology my friend? Plus no matter how properly you schedule in some of these programmers, they would rather slack off than do the job on time. Like last time we had these guys who were working on a DAW and their sound alogrithm was so off that we didn't even move forward with the project.

Doesn't that simply import each row as a single field per row? Seems to me your code is working.

Getting one field where multiple fields are expected was a problem. :confused: The original logic was just to remove any commas found between double-quotes. Doing this with the single field (of comma delimited values) just pushed everything together and made a mess. A little added logic to detect if the entire line is wrapped fixed everything. :) Easy. The point was that sometimes you just have to take what the client gives you and make it work...that and how lazy (or stupid) the client's dev was for not understanding what the problem was. :)
