OpenRefine extensions
You can install the following extensions to add functionalities to OpenRefine. We do not vouch for the function of any of these extensions. Some only work with earlier version of OpenRefine, or with third-party distributions. See how to install an extension.

| D2Refine | A clinical study metadata harmonization and validation workbench to 1) convert restrictions (specified in a spreadsheet-like interface) into a clinical model; and 2) provide reconciliation services leveraging the Common Terminology Services 2 (CTS2). Manual. | Deepak K. Sharma | 2.7 |
Legacy Extensions
These extensions were produced in the past and are good examples of desired uses of OpenRefine. They are maintained here for historical reference, and in case a contributor would like to renew them.
| Extension Name | Description | Authors | Suggested compatible version |
|---|---|---|---|
| LODRefine | LODRefine is actually OpenRefine with integrated extensions that make transition from tabular data to Linked Data a bit easier. Integrated extensions are: RDF extension, DBpedia extension, CrowdFlower crowdsourcing extension, Stats extension | Sparkica | |
| VIB-BITS Diff plugin | Adds a "diff" tool which compares two text values. Manual PDF. | VIB-Bits | 3.4.1. The VIB website states "We are investigating how to provide [the diff plugin] again with version 3.4 of OpenRefine." |
| VIB-BITS Save facets plugin | Adds support for save facet settings and re-apply the same facets at a later time. Manual PDF. | VIB-Bits | Unknown. The VIB website states "We are investigating how to provide [the diff plugin] again with version 3.4 of OpenRefine." |
| geoXtension | geoXtension is based on GDAL, Proj, and GEOS libraries. Adding this extension takes a lot of time, usage of the ready-made docker is recommended. | giTorto | (circa 2.6) |

Reconciliation services
OpenRefine can connect to several reconciliation services. You can find information about them at:
- Reconcilable Data Sources in our wiki
- Reconciliation Software at the Reconciliation API Census
- Reconciliation Services at the Reconciliation API testbench (generated by a SPARQL query on Wikidata)
Client libraries
You can automate some OpenRefine operations using one of the existing libraries. Those libraries are using the OpenRefine API.
