Bulk Markup on Selling Price

Bulk Markup on Selling Price

Hi, 
So, we want to markup all of our prices 10% for this upcoming year. I tried the price list option, but it only applies to certain documents or clients that you select.
Is it possible for me to update the prices in bulk by exporting all of my products, changing the prices in excel with a formula, and then importing them again?
Also, would the prices be updated in my connected Shopify store as well?
I have only exported a list with item name, sku, unit and selling price.
