**Excel History**

\
Excel was released in 1987. During this period, data management was a huge challenge in industry. We know companies, banks, govt. offices used to maintain data either in big registers or files. Major problems related to data handling were: \
\
 Data Storage \
 Data Transfer\
 Calculations \
 Reports

\
To overcome this problem Excel became a very good solution in industry. Excel is similar to register or notebook. We have to look it very differently.

\
 Like in register, We used to prepare index like tabular form structure (rows & column). Similarly excel has rows & columns structure.\
\
Register can have\
Max Rows – 100\
Max Col- 100\
\
Excel can have\
Max Rows – 1048576 (As shown Below)\
Max Col - 16384 (XFD is the 16384th column in excel)<br>
