FAQ
To use JSON Generator, specify a JavaScript object as your template in the left box. The tool will clone this object infinitely deep. You can include template tags in string values, which will be replaced with random values when you click 'Generate'.
Template tags are placeholders that generate random data. For example, {{firstName}} generates a random first name, {{email}} generates an email based on previously generated firstName and surname, and {{date}} generates a random date. You can find a full list of tags and their usage in the help section.
You can choose the indentation for the generated JSON from the dropdown list. The available options are 'Compact', 2 spaces, 3 spaces, and 4 spaces.
After generating the JSON, you can copy it to your clipboard by clicking 'Copy to clipboard'. Alternatively, you can download the generated file by clicking the 'Download' button.
Yes, JSON Generator remembers your last template in the localStorage. If you want to reset it, you can click the 'Reset' button to reset both the template and the UI.
