macOS Import or Export a .numbers or CSV file?

[BadWolf13]

I've got this program that has an array of objects, which I'd like to be able to import or export to/from a common spreadsheet file type. So far I haven't had any luck finding a way to write the info to a simple CSV, XLS or Numbers file. Is there an API for this, or does anyone have any idea where to start? I really don't have a clue on this one.

It's not a complicated format, just values separated by commas. See here:

Simplest way would be to create the data with NSMutableString and then write it to file.

No offense dude, but you don't need to tell me the painfully obvious, the merely obvious will do. Such as, how to write to a file in obj-c?

Edit: use the suggestion below

Use the NSString method writeToFile:atomically:encoding:error:

Edit: Or use the suggestion above.
