HOW TO extract table on a public web page as a CSV file

Tables within web pages on the internet don't provide interactivity most of the times and data is presented through plain HTML tables unless developers of the website implement it through client-side functionality through something like a jQuery plug-in such as DataTables to make data more accessible. In such cases, you cannot filter or sort unless you manually copy the table to a spreadsheet and then use the functions of a software tool like Excel. 

To minimize the steps, it is better to use bookmarklets that can create a CSV file from an HTML Table. Below are such bookmarklets graciously shared by some good folks on the internet -

• Stoyan Stefanov's ReactiveTable bookmarklet
• Davin Studer Export to CSV bookmarklet
• ShareProgress' TableThis bookmarklet 

The screenshot shows how ShareProgress' TableThis bookmarklet can inject code to make a table within a Wikipedia page to be downloaded as a CSV file

Bookmarklet code needs to be relatively short because of browser limitations on the length of valid URLs — only 2000 characters are accepted in a URL. It’s possible to build  complex and interesting functionality if you can reference larger external scripts.
