The world’s leading search engine company, Google, has introduced a program to compete with software giant Microsoft’s Excel program. The program currently in the limited experimental stage and a release date has not yet been determined.
The official Google blog page reveals that the program is used in Google and that the program that can be later updated on the internet page can be seen instantly by the recipient. Google said 10 people will be able to work on the same program simultaneously.
