Create Excel file in iPhone programmatically

I want to create a Excel supported file which c开发者_JAVA百科ontains strings and images programmatically. I tried to create a .csv file, but I am not able to .csv file with both string and image.

There are many possibilities. The easiest way is to create CSV-Files but you have to take care which seperators excel uses. For checking that you should create a spreadsheet in excel and save it as csv and take a look into that file using any text-editor.

Another approach is to use SpreadsheetML and here a link to the msdn XML Spreadsheet Reference

Otherwise just create a simple xlsx-file with excel, unzip that file and take a look into that the unziped files.
