Share This:

Are you looking for a way to change the default CSV open option for Mac? One of the most common file formats used for data exchange is CSV (Comma Separated Values). If you’re a Mac user, then you know that when you double-click on a .csv file, it will open in Numbers by default. But what if you would like to open your CSV files in Excel instead?

In this blog post, we’ll show you how to easily change the default program used to open your CSV files on your Mac. This way, any time you double-click on a .csv file, it will automatically launch in whicheer program you choose.

The first step is to find the file that you want to open and right-click (or control-click) on it. This will bring up a context menu with several options. Select “Get Info” from this menu and a new window will appear with information about the file.

Next, look for the “Open With” section of this window and click on the arrow next to it. From here, select whichever program you want the file to be opened with by default (in our case it’s Excel). Make sure to check off the box next to “Always use this app to open .csv files” so that all future .csv files are opened with this program as well.

That’s all there is to it! Now anytime you double-click on a .csv file, it should automatically launch in Excel instead of Numbers. This can save quite a bit of time if you frequently work with CSV files, as there is no need to manually select which application each time they are opened.

We hope this guide has been helpful in showing how easy it is to change the default program used for opening CSV files on your Mac. If you have any questions or comments please feel free to leave them below and we’ll be happy to help out!
