// How to use.
// Log on to Audible, and open up your library.

// Next, you want to run this entire file as a script on the page.
// Chrome, Firefox and Internet Explorer does this differently.
// For chrome, press F12 to open the Chrome Dev Tools, and click
// on the Console. Then paste in this whole file in the console
// window and press enter.

// But first, set the following settings:

// How frequentyly should the script ask for book information?
// Too often and Audible might look at you angrily.
// Too slow and it will take longer to grab the information.
var requestBookDataFrequencySeconds = 3  // This number is in books per seconds.

// Do you want the data shown on screen in a table or as raw JSON data?
var exportFormat = 'html' // Options: 'html', 'json' or 'excel'

// Note that even with 'excel', you may have to copy-and-paste the resulting text
// first into a text file like a NotePad. Not sure why, but it seems to make it better for Excel.

// If you want a HTML table, do you want it to include the book thumbnail?
var exportHtmlIncludeImage = false
