Which one is for you

Pick OpenRefine if

  • Fits if you have a messy list of names or addresses to tidy
  • Works for people who reconcile data against Wikidata

Look elsewhere if

  • 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

Pick VisiData if

  • Fits if you spend your day in a terminal and need a quick look at a data file
  • Works for people who know a little Python

Look elsewhere if

  • Not for you if you want a mouse and menus, since there is no graphical or browser interface
  • Skip it if you want Excel-style formulas, as calculation uses Python expressions
  • Watch out: Windows use goes through WSL or MSYS2's Python
  • Watch out: there is no phone or browser version

Value for money
AFree under the BSD 3-clause licence to download and run, with donations welcome.
AFree and open source under GPLv3, installed with pip, Homebrew, conda or a package manager. A program anyone can download and run counts as free and substantial.
Free plan and trial
AFree outright, with no cap or paid tier.
AThe whole program is free with no cap and no account. Its pricing page mentions paid plans that fund development, which you don't need.
Features
CFaceting, clustering, reconciliation and undo. It cleans data well but has no cell formula grid, so it is a different job from a spreadsheet.
CMany file formats, keystroke analysis, Python expressions and replayable sessions. Calculation is done in Python, not Excel-style formulas, which is a gap for a spreadsheet.
Ease of use
CYou download and run it, then learn faceting and its expression language. No store rating on record, and the Windows zip includes its own Java.
DNo store rating on record. It is a terminal program run from a command line and learned through keystrokes.
Platforms and integrations
CA program for computers only, on Windows, Mac and Linux, linking to Wikidata and Wikibase.
CMac and Linux, with Windows only through WSL or MSYS2. It is a program for computers, and Python, SQLite and pandas links.

    Worth knowing

    OpenRefine

    • 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.

    VisiData

    • It is a terminal program with no graphical or browser interface.
    • Windows use is through WSL or MSYS2's Python, per the install page.
    • The pricing page mentions paid plans that fund development, but their contents did not load in plain text, so their prices are not recorded here.
    • It is not built for formulas in the Excel sense; calculation is done in Python expressions.

    How this page was made

    • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
    • The grades are our own, from each tool’s review or report card. The GPA is their average.
    • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
