This hands-on session introduces OpenRefine, a powerful, free, and open-source tool for exploring, cleaning, and transforming messy data. Working step by step with a real dataset, participants will learn how to examine data, correct and standardize inconsistent values, and transform it efficiently to make it ready for analysis. The session emphasizes transparency and reproducibility, showing how every step can be reviewed, shared, and reused. By the end, participants will be confident using OpenRefine to turn raw data into a structured and reliable dataset suitable for further analysis across a range of research contexts.
Participants are kindly asked to download and install the following in advance:
- 
OpenRefine (we recommend using the latest stable version 3.8.7):
