How do you actually execute changes in Spreadsheets day to day?

I’m trying to understand the current status quo of executing operations in Excel once data exists.

By execution, I mean:

• Entering or updating data
• Applying operations across rows/columns
• Mutating data using formulas, filters, copy-paste, etc.
• Repeating multi-step actions over time

In practice:

• Do you mostly do this manually with keyboard/mouse?
• Have you automated any part of this (formulas, macros, scripts, add-ins, AIs)?
• If yes, what pushed you to automate?
• If no, what makes automation not worth it?

I’m not selling or promoting anything. I’m mapping real workflows and friction.

Comments with concrete examples help.
If you’re open to a short DM about how you execute changes in Excel day to day, that would help too.
