About this tool

What does JSON Sample Generator do?

Generate realistic JSON records for development and testing. The workspace keeps the input and result together, making it easy to check the change before you use it elsewhere.

For example, you can generate realistic JSON records for development and testing before testing a layout with varied data.

What you can control

JSON Sample Generator stays deliberately simple: add the records, run the tool, and review the result.

How to use JSON Sample Generator

  1. 1

    Enter the records carefully and check that the unit or format is correct.

  2. 2

    Review the records and correct anything you do not want carried into the result.

  3. 3

    Run JSON Sample Generator, check the answer against your inputs, and copy the result if you need it elsewhere.

Tips for a better result

  • Save the JSON Sample Generator settings with any sample that needs to be recreated later.
  • Read the complete result rather than relying on the first line or preview alone.
  • Review generated values against the rules of the prototype or test that will use them.
