How to migrate wide Excel worksheet into SQL Server table

23 January,2020 by Tom Collins

Question: What is the limit on SQL Server Maximum Columns per table?  I have a very wide Excel worksheet and want to migrate the data to a SQL Server table - where we can then manage the data?

Answer: The standard SQL Server table maximum columns limit is 1024. Tables that include sparse column sets include up to 30,000 column

A Sparse column set combines the table's sparse columns and translates into a structured  representation. The column set is not stored physically in a table.
