Frequently Asked Questions: ENV to JavaScript Object
How do I convert ENV to JavaScript Object online without uploading sensitive files? ▾

How are nested objects or tabular columns mapped between ENV and JavaScript Object? ▾
When converting hierarchical structures (Flat key-value pairs (nested paths joined with underscores)) and tabular or config formats (Arbitrarily nested JS objects and arrays), our engine automatically flattens or unflattens dot-separated keys (such as address.city) and preserves numbers, booleans, arrays, and null values.
