OpenRefine

OpenRefine offers an effortless solution for tidying and unifying disparate, messy datasets. Accessible directly via your web browser, it simplifies complex data refinement tasks through an intuitive interface. You can easily filter, sort, and facet data to spot anomalies, then use built-in functions or custom General Refine Expression Language (GREL) to automate corrections. It supports linking and extending data with external APIs. This makes it an indispensable tool for anyone needing to prepare, reconcile, and improve data quality for reporting, analysis, or system integration.
