Can I create a .xls file programmatically in iOS?

I need to create a .xls开发者_JS百科 file from the Array data programmatically in iPhone. How can this be done?

Maybe you're in trouble, maybe not. The "old" xls format is a binary one and I am not aware of any free libraries which are able to read or write to that format. If this one is required, you're propably out of luck.

If however a more recent format will do you're back in business, because you can use xml (objc wrappers for lib2xml are readily available). Wikipedia features a short overwiev of the format which you might want to check out: Excel file formats on Wikipedia
