"A number of years ago, I came across a super useful tool for managing data   It is now an invaluable data tool we use every day. And it is free!

OpenRefine, formerly known as Google Refine, is a powerful open-source data cleaning and transformation tool for working with messy and inconsistent data.

OpenRefine is designed to help users clean, transform, and reconcile data from various sources, such as spreadsheets, CSV files, JSON, and more. It is particularly useful when dealing with data that may contain errors, inconsistencies, or duplicates, as it provides a user-friendly interface for data-wrangling tasks.

Here are some key features and functionalities of OpenRefine:

  • Data Cleaning: OpenRefine allows users to clean and standardize data by performing operations like removing duplicates, fixing typos, and correcting inconsistent formatting. It provides various facets and filters to help you identify and address data quality issues.
  • Data Transformation: You can perform various transformations on your data using OpenRefine, including splitting columns, merging cells, and applying mathematical or text-based functions. These transformations can help prepare data for analysis or integration into other systems.
  • Reconciliation: OpenRefine has a reconciliation feature that can help match data in your dataset with external data sources, such as databases, APIs, or online services. This can be useful for linking data to authoritative sources or resolving inconsistencies. 
  • Faceted Browsing: OpenRefine offers faceted browsing, which allows you to explore your data visually and filter it based on different attributes. This feature helps you gain insights into your dataset and understand its structure.
  • History and Undo/Redo: OpenRefine keeps a history of all the operations performed on your data, making it easy to track changes and revert to previous states if needed. This can be valuable when experimenting with data transformations.
  • Extensibility: OpenRefine supports extensions and plugins, which allow users to add custom functionality and enhance the tool's capabilities. This extensibility makes it adaptable to various data processing tasks.
  • Export and Integration: Once you've cleaned and transformed your data in OpenRefine, you can export it in various formats, such as CSV, JSON, or Excel. You can also integrate OpenRefine with other tools and systems through its APIs.

The databases you work with within Open Refine are saved on your local machine, not in the cloud which is a feature we like.

Since OpenRefine is open-source, it is continually improved and maintained by a community of users and developers. You can download and use OpenRefine for free, and it is available for Windows, macOS, and Linux platforms."
