Replace JSON Key Values

This GitHub Action replaces key values inside JSON files using a simple Object.Key=value syntax.
It is designed for dynamically updating configuration files (e.g., appsettings.json) in your CI/CD workflows.

📦 Inputs

files (required)

List of JSON files where values will be replaced.
Files must be separated by |.

Example:

files: "config.json|secrets.json"

replacements (required)

Pairs of Object.Key=value separated by |.
Supports nested keys, literal keys, and automatic type casting (number, boolean, null, strings).

Example:

replacements: "Database.Host=localhost|Database.Port=1433|FeatureFlags.EnableCache=true"
