EventCopy for Calendars av Brian E. Young

How it works

Go to your event page on any calendar site (Eventbrite, Luma, Facebook, and more)
Click the EventCopy icon in your Firefox toolbar to open the HUD
Click Scrape to automatically pull your event details: title, date, time, venue, address, description, and ticket link
Navigate to the calendar site where you want to submit your event
Click Fill to automatically populate the submission form with your scraped event data

Features

One-click scraping from any event page that uses standard web formats
Fills out event submission forms automatically, no copying and pasting
Highlight any text on a page and tag it to a field manually (great for sites that don't use standard formats)
Edit any field in the HUD before filling, so you can customize per calendar
Works on MediaWiki-based community calendars, Luma, Eventbrite, and most standard event submission forms
All data stays in your browser, nothing is sent to any server

Tips

If a field doesn't fill automatically, use the 🎯 button next to any field to click directly on the correct text on the page
Add your event's ticket or registration link once and it carries over to every calendar you submit to
Use the reset button to clear all fields and start fresh for a new event
You can even save frequently visited calendar and form pages and have it open and autofill. You still have to double check and hit submit on the form
