Is there a way to extract just the first line or n characters from a JSON file without having to download the entire dataset?

I am looking to extract specific information from a large JSON file that is 450 KB in size. However, I do not need to download the entire JSON file as I only require certain characters or lines from it. Is there a way to read n characters or line by line from the JSON file without downloading the entire file? If so, how can this be achieved?

If you're looking to enhance your HTTP requests, consider utilizing the HTTP Range header.

This RFC outlines the functionality of HTTP/1.1 range requests, partial responses, and the multipart/byteranges media type. The inclusion of range requests in HTTP is optional but serves to ensure that recipients who do not support this feature can still handle the request as a standard GET request without impacting interoperability. Partial responses are distinguished by a specific status code to prevent confusion with full responses for caches that may not have implemented this feature.
