Often you may want to use PowerShell to replace all commas with newlines in a particular file.
You can use the following syntax to do so:
(Get-Content team_names.txt) -replace ",","`n" | Set-Content team_names2.txt
This particular example replaces all commas with newlines in the file named team_names.txt and saves the results to a new file named team_names2.txt.
Note: You must use double quotes in this scenario when using the -replace operator.
The following example shows how to use this syntax in practice.
Example: How to Replace Commas with Newlines in PowerShell
Suppose we have a file in our current directory named team_names.txt that contains the names of various basketball teams.
We can use the Get-Content cmdlet to view the contents of this file:

We can see that the file contains the names of various basketball teams separated by commas.
We can use the following syntax to replace each comma in the file with a newline instead:
(Get-Content team_names.txt) -replace ",","`n" | Set-Content team_names2.txt
The following screenshot shows how to use this syntax in practice:

Notice that when we use the Get-Content cmdlet to view the contents of the new team_names2.txt file we can see that all commas have been replaced with newlines.
Each of the team names is now shown on its own line.
