Form AutoFiller is a Chrome extension that simplifies online form completion by allowing users to automatically fill form fields using a JSON object. This tool is particularly useful for developers and testers who need to enter data quickly without the risk of manual errors. Users can paste their JSON data directly into the extension, which will then populate the corresponding fields in the form, thereby saving time and enhancing productivity.

One of the standout features of Form AutoFiller is its support for complex data structures, enabling users to manage arrays and nested objects effectively. Additionally, it offers customizable settings to either auto-fill forms automatically or manually, depending on user preference. The extension also includes error notifications for fields that cannot be found, ensuring a smoother debugging process. With features like history management for previously used JSONs and the ability to clear forms quickly, Form AutoFiller is an essential tool for anyone frequently working with online forms.
