You can "open" any file without the program that created it installed:

C#

byte[] data = File.ReadAllBytes(pathToFile);

will do it for most situations.
The problem is in understanding it, and displaying data.

Think about it: a website just emits a stream of HTML: which you can read and work out what the website looks like - or you can feed that HTML into a browser application and it will do it for you. The latter is a lot quicker and simpler! :laugh:

It's the same with Excel: you can read the file, but unless your software understands Excel data format (and there have been a number of them over the years) you can't easily do anything with the data. You need to install Excel, or use a library which can read Excel data in order to use the information. Google can help you find an appropriate library - I have no idea what you are trying to do or what your priorities are, so it's best if you start searching yourself.

You can read and write Excel documents without Microsoft Excel installed in C#:
These are some of the open source tools you can use:
