1. Theme Switching

One of the standout features of this JSON viewer is its theme switching functionality. Users can easily toggle between light mode and dark mode. This is particularly useful for enhancing readability in different lighting conditions. The dark mode helps reduce eye strain during extended use, making it ideal for working late at night or in low-light environments. The theme preference is saved in the user's local storage, ensuring that their chosen theme is applied automatically when they revisit the tool.

2. Flexible Input Handling

The viewer supports multiple methods for inputting JSON data:

• Direct Paste: Users can paste JSON data directly into a large textarea. This is convenient for quick data entry and testing.
• File Upload: Users can drag and drop JSON files into a designated drop zone or select files via a file input dialog. This functionality allows users to easily load and process large JSON files without manual copying and pasting.

3. JSON Formatting

For users dealing with complex or poorly formatted JSON data, the tool offers a formatting feature. When invoked, this function beautifies the JSON, adding indentation and line breaks. This makes the JSON data much easier to read and understand, especially when dealing with deeply nested structures. Properly formatted JSON helps in debugging and ensures that data structures are clear and comprehensible.

4. Minification

Conversely, for scenarios where data size needs to be minimized, the viewer includes a minification feature. This compresses the JSON by removing unnecessary whitespace and line breaks. Minified JSON is beneficial for reducing file size and improving loading times, particularly useful in production environments where performance is critical.

5. Validation

The validation feature is crucial for ensuring the correctness of JSON data. It parses the JSON and checks for syntax errors. If the JSON is valid, a confirmation message is displayed. In case of errors, the tool provides detailed error messages that pinpoint the issue, helping users quickly rectify any problems.

6. Tree View Visualization

The viewer provides an optional tree view representation of the JSON data. This visualizes the JSON structure in a hierarchical format with expandable and collapsible nodes. It makes it easier to navigate through complex data by allowing users to expand or collapse sections as needed. This feature is particularly valuable for exploring large JSON objects and arrays, providing a clear overview of nested data.

7. Search Functionality

A powerful search functionality is integrated into the tool, allowing users to find specific data within the JSON. As users type their search query, the tool highlights matching results and provides navigation buttons to jump between them. This feature enhances data exploration, making it easier to locate particular values or keys within extensive JSON datasets. Users can clear search results and reapply searches as needed.

8. Download Option

For users who need to save their JSON data, the tool includes a download feature. This allows users to download the JSON data as a .json file. This functionality is useful for exporting data for use in other applications or for sharing with others. It streamlines the process of saving and transferring JSON data.

9. Font Size Adjustment

The viewer offers options to adjust the font size of the JSON data displayed. Users can increase or decrease the font size according to their preference, which is especially helpful for users with varying visual needs. This feature ensures that the text is readable and accessible, regardless of the user's display settings.

10. Progress Indicator

During data processing tasks such as formatting, minifying, or validating JSON, a progress indicator is displayed. This helps keep users informed about the status of ongoing operations, providing a visual cue that the tool is actively working on their request. It improves the overall user experience by managing expectations and preventing confusion.
