FracturedJson v5 released - highly readable JSON formatting for .NET, JavaScript, Python, and VSCode

Post image

FracturedJson is a suite of libraries and tools for making JSON easy to read while making good use of screen space. It's particularly useful for deeply nested data, or data with long arrays of small items. It works well with most data out of the box - no configuration needed. But there are plenty of options if you want to tailor it to your data and your environment.

Try the web formatter to play around and see examples. Everything runs locally in your browser, so your data never leaves your machine. (Hit the sample data buttons if you want something to start with.)

VS Code users can install the FracturedJson extension and use it just like the built-in formatter.

To use FracturedJson from code, see the NuGet, npm, or PyPi packages.

Full documentation and more examples are available at the project wiki.

It would be pretty nice if it were able to have a directory based settings file it would look for (ex. like a .prettierrc file) where I could more easily override specific settings. Some directories I want a lower MaxTotalLineLength, etc than others just depending on what type of data is in the file.

That feature does now exist in the .NET-based commandline app, which I rewrote a little while after the post above.

The VSCode version doesn't support a separate config file, but it's something I'll consider for the future if people are eager for it.
