WikiColumn by Matt M

A Firefox extension that lets you add columns from Wikidata to most datatables on Wikipedia. Right-click a table and choose WikiColumn. The sidebar will open to allow you to edit which column is "key" (e.g. movie titles, business names, city), and then select which properties from Wikidata you want to add as new columns to the table. The extension fetches the data from Wikidata and inserts it to the table.

Example Use Cases
- Add genre, run time, and review score to some award winner tables
- Add the opposite to the table of zodiac signs
- Add a link to the government website or coordinates from a list of cities
- Add the population of countries
