Conversion Guidelines
1. Flat vs Nested Structures
Root-level key-value pairs map directly to standard environment format. Nested objects are flattened using underscore separators (e.g., DATABASE_HOST).
2. Data Type Handling
Numeric and boolean values are converted cleanly to standard string representations suitable for environment runtimes.
Frequently Asked Questions (FAQ)
Nested objects are recursively flattened using uppercase path segments separated by underscores (e.g.,
database.host becomes DATABASE_HOST).
The converter will catch JSON parsing errors and display an informative notice in the output block so you can correct your brackets or quotes.
