- Check before download
Arrange dotenv layers, choose first or last precedence and a policy for missing variables. Inspect resolved values and dependencies. Quoted multiline values and declared defaults work. Secrets are masked, and no shell or process environment is read.
Method: dotenv-ordered-2026; $NAME, ${NAME}, ${NAME:-default}, ${NAME-default}
Local processing
Input stays in your browser worker, without requests, storage or content telemetry. Original backups and explicitly revealed exports may contain secrets; keep them local.
Resource limits
Combined input ≤1 MiB; text ≤200,000 characters (XML 100,000); depth 32 / nodes 20,000 per document; at most 1,000 rows/operations; output ≤2 MiB; worker deadline 5 s. Cancel terminates the worker. These application bounds do not guarantee a total browser heap cap.
Up to 19 additional layers and 1000 variables or edges; each expanded value up to 8192 characters and up to 200000 characters in total. Expansion recursion is limited to 32. Single quotes are literal; double quotes support escapes and interpolation. No command substitution.
Choose the profile and review diagnostics before using saved output. Editing, resetting or leaving cancels work and discards the preview. Save original backups separately; no source file is overwritten.
