Yes, Free JSON Formatter Pro and Validator Online tools will support the uploading of very large JSON files for formatting and validating your JSON files while preserving their structure. The only thing you will need to do is paste your large JSON data or upload your large JSON documents.
Is my JSON data safe when using an online formatter?

The way the checking and formatting of your JSON code works is that both processes are performed simultaneously and your JSON code will NOT be saved to the server, thereby ensuring that your JSON data remains private and protected.
