Frequently asked questions
Do I need an account to use the Text to JSON Array Converter?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the page.
Is my data uploaded anywhere?
No. The Text to JSON Array Converter runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What is the Text to JSON Array Converter used for?
In practice it gets used for three things: turning a copied list into a code constant. Building a fixture for a test. Preparing options for a select element. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Does the Text to JSON Array Converter work on a phone?
Yes. The page is responsive and the page works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
