</script>
<script src="http://example.blogspot.com/feeds/posts/default?max-results=9999&amp;alt=json-in-script&amp;callback=bloggersitemap"></script>


After adding the above code, replace http://example.blogspot.com with the address of your blog.

Customization:

- to change the color and font size of categories title, replace the values in red
- to change the color of the links, replace the value in green

Step 4. Click Options on the right side and select Don't allow (hide existing) for the reader's comments
Step 5. Finally, click the Publish button and View the page.

That's all!

Can you update this script? Blogger added pagination to the feeds and now any 150 post are shown on a single page, so the max-results=9999 is actually max-results=150.
You need to update it and make it work with multiple links, like:
https://example.blogspot.com/sitemap.xml?page=1
https://example.blogspot.com/sitemap.xml?page=2
https://example.blogspot.com/sitemap.xml?page=3

or

https://example.blogspot.com/atom.xml?redirect=false&start-index=1&max-results=150
https://example.blogspot.com/atom.xml?redirect=false&start-index=151&max-results=150
https://example.blogspot.com/atom.xml?redirect=false&start-index=301&max-results=150
https://example.blogspot.com/atom.xml?redirect=false&start-index=451&max-results=150
etc

*Later edit
Found this feed link that allows 500 posts on each page:
https://www.blogger.com/feeds/BlogID/posts/default?start-index=1&max-results=500
https://www.blogger.com/feeds/BlogID/posts/default?start-index=501&max-results=500
https://www.blogger.com/feeds/BlogID/posts/default?start-index=1001&max-results=500

etc

(replace BlogID with your own blogid number)
