Styling multiple files on Libre Office Calc

Question

Here's what I do now:

1. Get CSV file from extrenal source
2. Open it in Calc
3. Apply style (set colors, fonts, etc.)
4. Export as PDF

Is it possible to get rid of step 3? Somehow loading data to already styled document?

Columns on different CSV files are always the same, but rows might have different data.

I am open to other alternatives too.
