OpenRefine web platform helps in exploring the added data and can analyse data automatically and gain valuable insights from it. It removes inconsistencies in various datasets, understand anomalies in data and helps us to zoom in data.

Another useful feature is how Open Refine helps in cleaning certain datasets into some format and removing unwanted garbage data. It separates chunks of data, and can handle millions of rows of datasets, and do these tasks at this scale as long as your computer memory supports that.

OpenRefine can be used to link and extend your dataset with various web services. This is called reconciling data as a lot of thought process needs to be done before applying this. Consider the case of a dataset with input text being there in multiple languages. We can use Google Translate to detect the language which is being in the input text and identify which language each input text belongs to and map to language code.

OpenRefine is used by a lot of professional organisations and users. It’s open-sourced under BSD license and loved by the community with more than 7,500+ GitHub stars.
