JSON → XML bridging guide

Documents default element shaping so infra teams anticipate serializer output.

Developer notes

• Namespaces declarations are manual if XSD demands them. • JSON arrays flatten their parent tag (`servers` ⇒ repeated `<server_item>` siblings — toggle **Pretty-print** to see indentation vs one-line mode). • Large JSON payloads can freeze low-memory browsers.

When teams pick this route

• Publishing SaaS catalogs into stubborn XML middleware. • Generating QA fixtures for parsers. • Comparing payloads before partner onboarding.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter + whether row 1 holds column names (Auto delimiter follows locale only for convenience). JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Worked examples

Service manifest (shows nesting, booleans & XML escapes)

Sample input

{
  "service": {
    "name": "checkout-api",
    "enabled": true,
    "replicas": 2,
    "notes": null,
    "metadata": {
      "env": "prod",
      "owner": "Platform & Payments"
    }
  }
}

Sample output

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <service>
    <name>checkout-api</name>
    <enabled>true</enabled>
    <replicas>2</replicas>
    <notes />
    <metadata>
      <env>prod</env>
      <owner>Platform &amp; Payments</owner>
    </metadata>
  </service>
</root>

Arrays become repeated `_item` tags (pretty-print exposes indent options)

Sample input

{
  "endpoints": {
    "servers": [
      {"role": "primary", "latencyMs": 12},
      {"role": "replica", "latencyMs": 18, "readOnly": true}
    ]
  }
}

Sample output

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <endpoints>
      <server_item>
        <role>primary</role>
        <latencyMs>12</latencyMs>
      </server_item>
      <server_item>
        <role>replica</role>
        <latencyMs>18</latencyMs>
        <readOnly>true</readOnly>
      </server_item>
  </endpoints>
</root>
