Inspecting JSON is part of the developer's day, and there are some obstacles you have to overcome:
- Browsers by default only display JSON as a plain text string, making it near to impossible to make sense of complex json files
- When using custom MIME types - vendor specific ones, e.g. application/vnd.foo+json - most JSON formatter addons/extensions do not detect that the data is JSON and thus do not highlight them.
This post shows you what to do to get pretty JSON with custom MIME types:
JSONView pretty prints JSON, but falls short when you have custom MIME types. To get around that problem, you need to install application/...+json|+xml as inline - it prevents Chromium from downloading all +json and +xml MIME types.
No further configuration needed.
JSONovich displays JSON properly and has in-built support for custom MIME types:
- Open the addon list
- JSONovich preferences
- MIME types: Add...
That's all needed.
JsonViewer highlights JSON, but Opera still asks you to download the file instead of displaying it.
You need to configure Opera to show the specific MIME type:
- Open Preferences
- Add a new one and activate "Open in Opera"
