Config Converter

Convert configuration files between .env, appsettings.json, secrets.yaml, and config.toml. Works as a standalone utility — no authentication or project required.

Supported Formats

Format	Extension	Description
dotenv	`.env`	Standard key-value pairs.
ASP.NET Settings	`appsettings.json`	Nested JSON for .NET `IConfiguration`.
Kubernetes Secrets	`secrets.yaml`	YAML manifest with base64-encoded values.
TOML	`config.toml`	Tom’s Obvious Minimal Language.

All format combinations are supported in any direction.

Web Converter

Available at /converter in the dashboard. Side-by-side layout: paste or upload source config on the left, choose target format on the right, and the converted output appears automatically. Copy to clipboard or download.

CLI Usage


depvault convert --file <path> --from <format> --to <format> [--output <path>]

Flag	Description	Required
`--file`	Path to the input file.	Yes
`--from`	Source format: `env`, `appsettings.json`, `secrets.yaml`, `config.toml`.	Yes
`--to`	Target format (same options).	Yes
`--output`	Output file path. Prints to stdout if omitted.	No

Examples


# .env to appsettings.json
depvault convert --file .env --from env --to appsettings.json --output appsettings.json
 
# YAML to TOML
depvault convert --file secrets.yaml --from secrets.yaml --to config.toml --output config.toml
 
# Preview to stdout
depvault convert --file config.toml --from config.toml --to env

The convert command is fully offline — no API calls, no authentication.

Edge Case Handling

Comments — Preserved when the target format supports them (TOML); stripped otherwise (JSON, YAML).
Multiline values — Expanded into proper multiline syntax per target format.
Special characters — Properly escaped or quoted in the output.
Nested keys — appsettings.json nested objects are flattened with __ separators in flat formats (e.g., CONNECTIONSTRINGS__DEFAULT). Keys with __ in .env are expanded into nested objects when converting to JSON.

Conversion Matrix

From \ To	`.env`	`appsettings.json`	`secrets.yaml`	`config.toml`
`.env`	—	Flat to nested via `__`	Base64 encode	Group by prefix
`appsettings.json`	Flatten with `__`	—	Base64 encode	Map to TOML tables
`secrets.yaml`	Base64 decode	Decode and nest	—	Decode and group
`config.toml`	Flatten with `__`	Map tables to objects	Base64 encode	—
