Installing the Right Tools
Messy data holds you back from contributing meaningfully to Wikibase. Whether it is typos, duplicates or inconsistent formats, getting your dataset ready for projects like Wikidata can feel like a chore.
That is where Flookup comes in, a free Google Sheets add-on that improves prepping and cleaning data with the help of advanced fuzzy matching algorithms. It takes what Google Sheets already provides by default, adds a bit to it and enhances everything significantly.
In this tutorial, we will take a list of museums and guide you step-by-step through cleaning it, formatting it to align with Wikidata’s structured requirements, so you can confidently apply the same process to your own datasets.
