The tool is very easy to use, you just need to upload your CSV file and it will do all the work for you. You don't have to write any code! It's also very quick. I wish there was an option to download the data directly into Excel or Google Sheets so that I didn't have to export it from the app every time I wanted to look at it. It's a great way to quickly pull data straight from your website and add it to a spreadsheet. We're using this tool to aggregate our site traffic data from multiple sources so we can compare them.
