What are the features of MS Excel​

Then here are the excel features that you need to get a hold of:

Learn to use shortcuts. Once you are able to live without the mouse, you get the speed that counts. There are two types of shortcuts - one where you press a set of keys sequentially - like Alt>H>O>I to adjust column width. And the second where you simultaneously press a combination of keys - like Ctrl+Shift+L for applying filters or Ctrl+1 for the format numbers dialog box. It takes repetition to get the speed but once you are there, you get an edge.
Learn excel functions and apply them to build formulas. Start with easy ones like SUM, COUNT, SUMIF, COUNTIF, IF etc, then move to VLOOKUP, SUMIFS, COUNTIFS, HLOOKUP, INDEX, MATCH, then move to building nested complex formulas like IF inside an IF, VLOOKUP with HLOOKUP, INDEX+MATCH and so on.
Learn about data analysis and data aggregation. This includes tools like Pivot table, solver, goal seek, data tables, descriptive statistics, regression.
Learn about conditional formatting. Style and colour your spreadsheets.
