Hi,
To view or edit CSV files in Microsoft Visual Studio, you have to install some Excel viewer extenstion. You can use the following one, which is free:
Click on the
extension icon in the left pane, to see the available extensions and search for "
excel viewer":
![visual studio excel viewer csv editor](https://www.promcase.com/microsoft_visual_studio_excel_viewer_csv_editor.png)
Open the extension and click on
Install:
![visual studio install excel viewer to edit csv files](https://www.promcase.com/microsoft_visual_studio_install_excel_viewer_to_edit_csv_files.png)
After the extension is installed, you need to open the folder with your CSV files. Click on File > Open Folder. When the folder is opened and files are listed in the column, click on the file with right mouse button and select
Open With:
![visual studio open folder csv](https://www.promcase.com/microsoft_visual_studio_open_folder_open_csv_file_with.png)
Then, in the search box, click on
CSV editor:
![visual studio open csv file in editor](https://www.promcase.com/microsoft_visual_studio_open_file_csv_editor.png)
You should see the CSV file's content. Excel Viewer extension uses comma as a default CSV separator, so you may need to change it to semicolon. You can change it in
Settings >
Extensions >
Excel Viewer >
Separator:
![visual studion change csv separator from comma to semicolon](https://www.promcase.com/microsoft_visual_studio_excel_viewer_change_csv_separator_colon_semicolon.png)
