UK public data, made legible.

Vast amounts of UK public data are open in name only — published as bulk CSV, XML or PDF for legal compliance, but practically illegible to anyone without significant technical skill. Plain Data turns that data into fast, searchable, well-visualised products.

Why this exists

Companies House publishes monthly bulk CSVs. NHS England publishes spreadsheets. DVSA distributes weekly bulk MOT history files. HM Land Registry releases 32 million property transactions in one flat file. The data is legally accessible but practically illegible to anyone without serious time and skill.

Plain Data is a public-data interpreter — translating these datasets into forms ordinary people, journalists, councillors and analysts can actually use. We don't editorialise; we make data legible. Numbers come with context, methodology, and caveats. More about the project →
