How does a dot-notation key like server.port become nested XML?

Each dot-separated segment becomes a level of XML nesting, so server.port=8080 produces a 8080 structure inside the document's root element.

What .properties syntax is supported?

Standard key=value or key:value lines, with # or ! comment lines, matching the classic Java .properties format.

What happens with a line missing a separator?

Parsing stops and reports the exact line number, so you can fix the malformed entry before retrying.

Properties to XML Converter

Overview

Introduction

Migrating a Java .properties config into an XML-based system means rebuilding the nesting a flat key like server.port only implies.

This tool does that automatically.

What Is Properties to XML Converter?

A converter that parses .properties text into nested JSON, reusing the existing Properties to JSON Converter.

It then converts that JSON into XML.

How Properties to XML Converter Works

Each key=value line is parsed, and dot-separated key segments build up nested objects.

The resulting JSON value is converted to XML with a synthetic root element wrapping everything.

When To Use Properties to XML Converter

Use it when migrating a .properties config into a system that expects XML.

It's also useful for converting a Java build tool's config, or a locale/resource bundle file, into XML for a different toolchain.

Often used alongside XML to Properties Converter, Properties to JSON Converter and JSON to XML Converter.

Features

Advantages

Reconstructs nesting from dot-notation keys automatically.
Runs entirely client-side.
Reports the exact line of a malformed entry.

Limitations

Every value becomes an XML text node; there's no type inference (numbers and booleans stay as plain text content), matching how JSON to XML Converter behaves too.
The root element name is always a generic synthetic wrapper, not something derived from your keys.

Examples

Reconstructing nested XML

Input

server.host=localhost
server.port=8080

Output

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <server>
    <host>localhost</host>
    <port>8080</port>
  </server>
</root>

The dot-notation keys rebuild the nested <server> element.

Best Practices & Notes

Best Practices

Use consistent dot-notation depth for related keys, mismatched depths (e.g. both 'server' and 'server.port' as keys) can produce unexpected structure.
Keep key names valid XML identifiers if you need them preserved as element names exactly.
Use XML to Properties Converter afterward to confirm a round trip reproduces your original file.

Developer Notes

This composes the existing `propertiesToJson` and `jsonToXml` functions; no parsing logic is duplicated.
