OpenRefine is a free, open-source tool for working with disorganized data: cleaning (heterogeneous, incomplete, erroneous or noisy data, poorly normalized), preparing (format, organization or coding of data not adapted to the analysis tool or the questions to be explored), enriching (cross-referencing with other data or retrieval of information from the Internet), formatting (modifying the organization of a file and the content of cells, in graphic mode or with formulas).

This software can be downloaded locally, allowing you to keep your data private before sharing it with others.
