dotnet-json 1.1.0

dotnet-json

dotnet-json is a command line tool for working with and manipulating JSON files for example in CI/CD pipelines.

dotnet-json allows you to do basic manipulation of JSON files like setting the value of a specific (nested) key, or deleting a key, as well as merging two or more JSON files into one.

Installation

dotnet-json can be installed as a .NET Core (global) tool or be downloaded directly from the GitHub releases.

To install dotnet-json as a global tool, run the following command:

dotnet tool install -g dotnet-json

Or, if you already have dotnet-json installed and want to update it to the latest version, run the following command:

dotnet tool update -g dotnet-json

Usage

When you installed dotnet-json as a .NET Core global tool, you can run it as either dotnet json or dotnet-json.

dotnet-json has 5 sub-commands, merge, set, remove, get and indent.
