This is a curated list of online productivity tools I use and recommend. The list will grow over time, but inevitably some of them will move or disappear. Please let me know in the comments if you find a missing or broken link.
Edit HTML tables
Professional HTML Editor is an online WYSIWYG HTML editor which allows you to easily convert any document file to clean HTML code, or clean existing code. I find it particularly useful as a tool for editing HTML tables. You’ll need to subscribe (or know your way around Developer Tools) to use it on a Friday. Try it out at https://htmlg.com/html-editor/
