In the context of this tweet most important differences are:
SQL is a language for querying databases.
Most common used databases are relational databases. With relational databases you can setup, wel, relations and constraints.
Imagine you have 2 tables (2 excel sheets) one with people, and one with home ownership. You can set the following constraints: (1) each person shows up only once in the people table. (2) every home owner must refer to an existing person in people table.
When modifying the table contents, the system checks if no constraints are violated.
Excel, just like a badly designed relational databse, would, for example, have no problem with duplicate people, or home ownership referring to non-existant people.
