#2CSV as serialization format? Ouch. Could we do better? My experience with CSV has been nothing but pain in the past. Ambiguous formats, quoting issues, incompatible libraries between languages and popular GUI tools like Excel or data vis apps.
I wonder if there's anything better.

The point of the format is that you get json metadata to avoid the ambiguous issues (and it also has requirements on the csv format to use, although whether people will follow them is a different matter).
On the other hand, I used their python API a bit and for loading tables it's way too complicated, with the documentation going into great detail for faffing with metadata but not for actual loading (and nothing like a simple `read_datatable` function).
That said, because it's just a folder with CSVs you can just read them individually, although then there's nothing to take advantage of the metadata automaticall.

#4Happy to see this on the frontpage. I work for the Open Knowledge International, which develops the Frictionless Data standard. Feel free to ask me anything, and I'll make sure myself or someone else from the team answers it.

I hate csv so much. Simply opening a csv in Excel and saving it breaks the format so much that most parsers cannot understand it anymore. Plus there is no way to know which encoding the csv came in - Notepad++ might say one thing and PowerShell will say another. Have fun figuring out why cyrrilic characters or umlauts cause issues in your scripts...

Although there're multiple issues with CSV, it's the de facto standard for tabular data. We try to avoid its pitfalls by limiting how the CSV must be (UTF-8, header in the first line, etc.)
There's a brief explanation on why CSV was selected on https://specs.frictionlessdata.io/tabular-data-package/#why-...

Hi,
(I work on the Frictionless Data specifications and tooling at Open Knowledge International.)
CSV has many, many warts. However, it is the best thing we have right now for serialising data in a way that is easily read by humans (and consumer-grade software) and machines. Libraries like our Tabulator [1] which is used under-the-hood help provide an API to deal with many of the gotcha's when dealing with the format.

Point taken about the API. The Data Package [1] and Table Schema [2] libraries are generally designed as low-level libraries for building higher-level applications using the specifications. goodtables-py [3] is an example of a higher-level application built on top. But, point taken, we will look at it, and we'd welcome your feedback on the issue tracker [4].

I think the excel issue is a problem with excel, not csv. Why can't excel preserve the format of the file?

Problem is not CSV, it's Excel. It's hard to blame format, when application is insane enough to use locale settings to determine file parsing
