Introduction to OpenRefine and Regular Expressions

OpenRefine is a powerful free and open source tool for working with messy data: cleaning it and transforming it from one format into another. This first day will teach you to use OpenRefine to clean and format data effectively and automatically track any changes that you make. Many people comment that this tool saves them months of work trying to make these edits by hand. Day 2 will introduce learners to regular expressions, which are used in a lot of programming and searching applications to enable sophisticated pattern matching.
