The aim of this training is to help you use OpenRefine on your own data. This can contain subjects like:

load data files, import and parse data files from a URL
clean data files: rename columns, transform and edit cells, split multivalue cells...
transform data from one format to another: e.g. merge data from two files using  a column that is common to both data files, create new rows based on columns and vice versa...
export cleaned, transformed data
data manipulation pipelines
data dashboards
