help to create a sheet


Hi. I am new in smartsheet and I am looking to create a sheet to entry data for services offers to our clients. For example:

  • John Doe received a service on October 30th, January 10th, January 15th.....
  • Jack Smith received a service on Septmber 25th, September 30th, November 3rd...

Our programs runs until September 2025 so I don't see myself creating a column for each day during the next 2 years.

What could I do?
