Viewer for JSON files that can be GBs large.

Inspired by a Question on Software Recommendations, I wrote this viewer for very large JSON files. It can open files of 1.4 GB in size or even larger, as long as you have ~7 times the amount of RAM on your machine.

System requirements

  • Windows 7 SP1 or higher
  • .NET 4.5
  • 64 bit recommended (unless you open "small" files with less than 300 MB)


Huge JSON Viewer (13.8 MB)

Huge JSON Viewer (17.4 MB)


UI with tabs and filtering capability:
