Converting Deeply Nested Plist Structures to JSON

Deep Nesting in Plist Files

Real-world plist files often contain multiple levels of nesting: arrays of dictionaries, dictionaries containing arrays of dictionaries, and so on. The converter handles arbitrary nesting depth.

Plist Example

<dict>
  <key>Accounts</key>
  <array>
    <dict>
      <key>Name</key>
      <string>Personal</string>
      <key>Servers</key>
      <array>
        <dict>
          <key>Host</key>
          <string>imap.example.com</string>
          <key>Port</key>
          <integer>993</integer>
          <key>SSL</key>
          <true/>
        </dict>
        <dict>
          <key>Host</key>
          <string>smtp.example.com</string>
          <key>Port</key>
          <integer>587</integer>
          <key>SSL</key>
          <true/>
        </dict>
      </array>
    </dict>
  </array>
  <key>DefaultAccount</key>
  <integer>0</integer>
</dict>

JSON Output

{
  "Accounts": [
    {
      "Name": "Personal",
      "Servers": [
        { "Host": "imap.example.com", "Port": 993, "SSL": true },
        { "Host": "smtp.example.com", "Port": 587, "SSL": true }
      ]
    }
  ],
  "DefaultAccount": 0
}

Tree View Navigation

For deeply nested structures like this, the tree view is invaluable. You can expand nodes level by level: root dict -> Accounts array -> first dict -> Servers array -> individual server dicts. Each node shows its type badge and item count.

Pattern: Array of Dicts with Nested Arrays

This pattern (array of dicts where each dict contains its own arrays) is extremely common in Apple configuration files. Mail accounts, VPN configurations, Wi-Fi network lists, and printing presets all follow this structure.

Preserving Structure

The converter preserves the exact nesting structure. No flattening or key-path collapsing is performed. This means the JSON output can be converted back to plist and produce an identical file.
