Opening CSV files in Excel 2016

For me the solution was to:

Data > From Text > Choose your csv file

Then you can define all the import settings for csv files.

CSV files are character separated value files, not necessarily comma separated. For more than half the world the separator character is a semicolon (;), not a comma (,)

Excel 2016 properly respects your Windows regional settings, and uses the specified List Separator character

One solution is to change your regional settings for the List Separator attribute to the character you want Excel to default to using, e.g. a comma (,)

This can be changed in the operating system Control Panel, under Region settings, Additional Settings, List separator

For various reasons some people seem to have the incorrect regional settings for the culture they most commonly work in, and therefore have semicolon as the default separator

If you prefer not to change your operating system regional setting to what you think is normal for CSV files, you can change the default behavior in Excel with the Use system separators checkbox under the File/Options/Advanced menu

If you want custom options each time you open a CSV file, use the Data/From Text menu, but this becomes slow and awkward for lots of files

I've found a way of saving messy CSV files into a nice table format but I'm not sure if it will work for your case.

Data -> New Query -> From File -> From CSV

By opening the CSV file this way, a pop-up 'Query Editor' window will appear with a nicely organised table format where you can edit, save and load into your excel sheet.

I hope this helps.

I found another way to fix this, without changing your windows local settings. In Excel, you go to File > Options > Advanced. Un-check the "Use System Separators" within the Editing Options and change the Decimal separator with "," and the Thousands Separator ".".

Even it does look more like a bug than a feature of Excel 2016, it works without changing the Windows Local settings, and it's just a local Excel change.
