How does the Kubernetes Secret conversion handle values?

Kubernetes Secrets require values to be Base64-encoded in the 'data' field. Toolbox encodes all variable values client-side into valid RFC 4648 Base64 strings ready for kubectl apply.

Does the converter preserve comments and quotes?

Yes. Lines starting with # are captured as comments, while unquoted values with inline comments have their comments safely stripped. Both single and double-quoted strings are supported.

Can I convert nested JSON keys like app.database.port?

Yes! When choosing JSON output, you can toggle between a flat dictionary and a nested JSON tree that parses dot-notated variable names into sub-objects.

Is my proprietary API key or password secure?

Absolutely. All parsing, formatting, and Base64 encoding happen 100% locally in your browser's V8 engine. No sensitive keys, database passwords, or credentials ever leave your machine.

What is the Value Masking toggle?

Enabling 'Mask Secrets' replaces all sensitive values with bullet characters (•••) while keeping variable names and schema formatting intact. This is ideal when taking screenshots or streaming live demos.
