.env to XML Converter

Most of modern infrastructure prefers structured formats, but a surprising amount of production software still speaks XML: .NET web.config and app.config sections, Java property frameworks, enterprise service buses, SOAP-backed tools, NAnt and Ant builds, and schema-driven data pipelines. When a .env file has to feed one of those systems, someone has to build the document by hand — and that is exactly where broken configuration is born: an & in a connection string silently swallowed, a key starting with a digit producing an invalid element, a boolean arriving as the string "false", or a nested structure collapsed into a flat mess.

The .env to XML Converter produces a well-formed XML document from your .env in one click. Each variable becomes an element with its value as text content, types are detected so numbers, booleans and null arrive natively, and keys split by a separator can be expanded into a real nested hierarchy. Every special character is escaped according to XML 1.0, keys that would break the grammar are sanitized with a warning, and the root element name is yours to choose.

Everything runs locally in your browser — nothing is uploaded, quoted values are unwrapped correctly, duplicate keys are flagged by line number, and both compact and pretty-printed output are one toggle away.

• One-click conversion: paste .env, get a well-formed XML document.
• Type-aware values: numbers, booleans and null are detected automatically.
• Nested elements: expand FOO__BAR into child elements with a configurable separator.
• Full XML escaping: & < > " ' handled correctly in every value.
• Safe element names: invalid keys are sanitized and flagged, never breaking well-formedness.
• Custom root: choose the root element name and xmlns-style attributes if needed.
• Compact or pretty: toggle indentation on or off for pasting into minified config.
• Duplicate detection: repeated keys are reported with their line numbers.
• Copy / download: clipboard or a .xml file in one click.
• Private: all conversion happens in your browser.

1. Paste your .env content into the input box, or click Load sample to see typed values, special characters and nested keys.
2. Choose the root element name that wraps the whole document (default: environment).
3. Toggle options. Type detection, nested keys with a configurable separator, and compact vs pretty output.
4. Click Convert. The XML document appears instantly on the right.
5. Review warnings. Sanitized element names and duplicate keys are listed above the output.
6. Copy or download the result as an .xml file.

Example 1 — .NET web.config. An ASP.NET developer converts PORT, CONNECTION_STRING and FEATURE__DEBUG into XML layout for a config section. The connection string containing & and = becomes escaped text content that .NET reads back byte-for-byte.

Example 2 — Legacy enterprise integration. A team migrating old configuration into an ESB pastes their .env and produces a schema-shaped document; nested keys become nested elements that the schema expects.

Example 3 — Java property bridge. An engineer converts .env values into an XML profile consumed by Spring-style configuration, keeping DEBUG as a real boolean and PORT as a number for typed property binding.

Example 4 — Configuration archive. A platform team keeps an XML export of production .env values as a versioned artifact, generated in a few seconds instead of being maintained by hand.

Example 5 — Data pipeline. A data engineer feeds the generated document into a schema-validating pipeline and the & in values no longer breaks parsing, because every special character is esc-escaped in the output.

• Always well-formed: correct escaping and valid element names, guaranteed.
• No transcription errors: the XML is derived, not retyped.
• Correct types: numbers, booleans and null arrive natively.
• Structured output: nested keys become real child elements.
• Safe values: &, quotes and angle brackets never break the document.
• Private & free: no upload, no account, instant results.
