Display Excel in webpage with data from SQL server and save

Question

Display Excel in webpage with data from SQL server with formulas and other stuff.

 

After making some changes i can save that excel back to server. 

 

Any Spreadsheet JS or something.

 

Actually i want to create a website for Online Excel Test, in which i want to show users a excel with data stored in SQl Server and user will perform some operations in that excel based on question and finally i will save that excel back to sql for examine that excel later.

 

 Tried different api but not able to accomplish this task???
