When using certain browsers, you can open a CSV data file and it will open as a website instead of a file. To correct this, please do the following:
- In Safari, with the CSV file opened, click File > Save As
- At the bottom of the pop-up, click "Format:" and change this to "Page Source"
- Click Save
- View the file contents in Google Chrome
- Click File > Save As, select CSV file
Now you can open this file in Excel to explore your data.
