Hello fannullone,

To create a patch file, enter the command below into the command line:

diff -u file1.json file2.json > patchfile.patch

In the example above, the diff output will be saved into a file named patchfile.patch.

Overwrite files with changes

Once the patch file is created,  you can use it to copy the changes to another file. For example, you may want to overwrite file1 with the changes from the updated file2. To do this, you could use syntax like this:

patch file1.json patchfile.patch

There might be some tools to diff JSON that could produce JSON patches. I am not aware of any. You could also probably create a JSON patch (RFC 6902) from the target JSON that completely overwrote the original JSON.

However, without more context, it's difficult to say if this would solve a particular problem. But I can see how it might make some issues worse
