Data Formats Playground
इस site की हर दूसरी lab यह मानकर चलती है कि आप एक data file पढ़ सकते हैं। यह lab वही सिखाती है, शून्य से — न code, न jargon। एक blood-pressure reading को चार तरीकों से लिखा देखें, फिर अपना JSON, XML या CSV live inspector में paste करें जो हर गलती सरल भाषा में बताता है। अंत में सात repair drills और एक graded quiz। केवल synthetic data।
One blood-pressure reading, written four ways — plain English, CSV, JSON and XML. Same fact every time, so you can see that a format is only a way of writing something down. Tap any note to light up the matching piece of the file.
The one fact
On 19 July 2026 at 10:30 in the morning, nurse Meera recorded Karen Whitfield's blood pressure as 128 over 82, sitting, left arm.
Everything below says exactly this. Nothing is added and nothing is lost — only the way it is written down changes. That is all a “data format” is: an agreement about how to write something down so a machine can read it back without guessing.
Plain English
How a human writes it. Perfectly clear to you, useless to a computer.
Think of it as: A handwritten note on a ward whiteboard. Any nurse can read it; no software can count it.

Good at
- Anyone can read it with no training
- Carries nuance and hedging ('appeared comfortable')
Watch out for
- A computer cannot reliably pull '128' out of it as the systolic number
- Nothing stops two people writing the same fact two different ways
- You cannot add it up, chart it, or search it across 10,000 patients
Where you meet it in health: Clinical notes, discharge summaries, referral letters — still the majority of what a hospital records.
