Reading data from excel using openpyxl

	#
	# I hate the documentation of openpyxl and it took me a while to undertand their stuff. So I decided to write down this code.
	# Has some wrapper functions that reads all rows from the excel sheet and also a function to read a particular row.
	# Add some code to the functions if you wish to do something on fly like adding values to list and sorting them later.

Last active February 18, 2016 19:29

C function to replace a sub string with something in a string.

	/*
	* C function to replace a sub string with something in a string. Would suggest to use glib to avoid memory overwritting or use mallocs.
	* You can use malloc() to assign memory to return string and get rid of the last argument but make sure to free it later.
	* This function replaces multiple instances of the found substring. To replace single instance, see the comment in the function.
	* If you want to dig more into it, check this out: http://creativeandcritical.net/str-replace-c
