OpenRefine report card
Good · out of 4.0 · graded Nov 13, 2026
Best for cleaning messy data on your own computer
OpenRefine is a free, open-source tool for cleaning and reshaping messy data, with clustering and reconciliation against Wikidata. It isn't a spreadsheet, so there is no formula grid for modelling, and support comes from a forum and chat.
Who OpenRefine is for
- Fits if you have a messy list of names or addresses to tidy
- Works for people who reconcile data against Wikidata
Who OpenRefine is not for
- Skip it if you want to build models with formulas, as there's no formula grid
- Too light for charts or dashboards, since it is a cleaning tool
- Tight if you want paid support, as help comes from a forum and chat
- Watch out: expect a learning curve before the clustering features pay off
Why OpenRefine gets a 2.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree under the BSD 3-clause licence to download and run, with donations welcome.
- AFree plan and trialFree outright, with no cap or paid tier.
- CFeaturesFaceting, clustering, reconciliation and undo. It cleans data well but has no cell formula grid, so it is a different job from a spreadsheet.
- CEase of useYou download and run it, then learn faceting and its expression language. No store rating on record, and the Windows zip includes its own Java.
- CPlatforms and integrationsA program for computers only, on Windows, Mac and Linux, linking to Wikidata and Wikibase.

Keep OpenRefine, or make your own?
Keep it
OpenRefine is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.8 is higher than 47 of the 63 other spreadsheet and database tools we grade.
What you could not
- A spreadsheet engine with its formulas.
- Apps for macOS, Windows and Linux that stay in step with each other.
What this rests on. OpenRefine’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is OpenRefine?
OpenRefine is free, open-source software for cleaning data, converting it between formats and extending it with web services and external data. It runs on your own machine, and you work with facets, clustering of similar values, and reconciliation against external databases. It is released under the BSD 3-clause license.
Worth knowing
- It is a data-cleaning tool, not a spreadsheet: there is no cell formula grid to build models in.
- Downloads are a Windows installer or zip, a Mac DMG and a Linux tar.gz; the Windows zip includes an embedded Java install.
- Support comes from a community forum and chat rather than a paid vendor.
Key features
- Faceting
- Drill through large datasets with facets and apply operations to the filtered view.
- Clustering
- Merges similar values to fix inconsistencies, using the project's heuristics.
- Reconciliation
- Matches your dataset to external databases through reconciliation services.
- Infinite undo and redo
- Rewind to any earlier state and replay the operation history on a new version of the data.
- Wikibase editing
- Contribute data to Wikidata and other Wikibase instances.
