Wanted, more information when I try to upload a CSV containing an error

Currently when a CSV containing one or more errors is saved the following error message pops up:

This makes debugging the CSV pretty difficult. It would be very nice if some more feedback about the cause of the error was provided.

I'm thinking this is part of a larger problem. In a way I understand why we support CSV editing in another way I would find it way better if we could get rid of it. 😈 Because you use the CSV editor it means that there's something wrong with the profile matrix editor or some essential feature(s) missing. I would like to know why it's preferable to use the CSV as input over the profile matrix editor?

I know that the CSV; for instance; mallforms Floats and Integers to Strings which causes problems like the one's were fixing in #1517. Typo's are more easily made and unfortunately this issue might take up more time than it should. It could be that the CSV is parsed just fine but the underlying calculation doesn't know what to do with the input due to missing numbers, missing attributes, accidentally deleted rows, but most likely - and this is purely judging by the Airbrake errors of late - Floats and Integers (as in numbers) that are interpreted as text.

Also in line with current ideas to merge the Topology and the technology matrix together into a single set of data, the CSV might be of little use or might become to much of a burden to keep supporting.

These are my 2 cents on the issue.

@DorinevanderVlies could you maybe send me a CSV that doesn't currently work on ETmoses?
