Can JSON preserve every plist type directly?

No. JSON has no native Date or Data type, so the export uses tagged objects for those values. Review the contract before using it as a round-trip interchange format.

Does reading Info.plist verify an application signature?

No. A parsed bundle identifier or entitlement value is metadata. Code signing and provisioning validity require separate checks on the actual bundle.

Are large integers preserved without limit?

Do not assume that. This parser represents XML numbers as JavaScript Number; very large integers may lose precision and original integer/real XML tags are not guaranteed to survive.

Property-list customs office · envelopes are not value types

XML paper and bplist00 carry the same restricted type family.

A property list is a typed value tree, not “some XML.” This studio detects the envelope, inventories native Apple types, inspects Info.plist identity, and makes every JSON loss declaration explicit.

Run a reproducible example

Inspect a typed Info.plist dictionary and see its JSON representation using public application identifiers.

Using an example replaces the current input, reference input, operation, and options. Public demonstration data only.

Inspect bundle identity and a boolean

Use an XML plist dictionary with CFBundleIdentifier and Enabled.

Input

<?xml version="1.0"?><plist version="1.0"><dict><key>CFBundleIdentifier</key><string>com.example.demo</string><key>Enabled</key><true/></dict></plist>

The hierarchy distinguishes a string from a boolean; it does not validate signing or entitlements.

CFBundleIdentifier:
com.example.demo
Boolean

Export the dictionary to JSON

Choose To JSON on the same typed dictionary.

Input

<?xml version="1.0"?><plist version="1.0"><dict><key>CFBundleIdentifier</key><string>com.example.demo</string><key>Enabled</key><true/></dict></plist>

The identifier stays a string and Enabled becomes true. Date and Data require tagged objects when present.

"CFBundleIdentifier": "com.example.demo"
"Enabled": true

How to use Apple Property List Studio

01
Prepare the input
Paste a property list or open a supported local plist file.
02
Choose the operation
Inspect its typed hierarchy or convert it to XML/JSON.
03
Review the evidence
Check Date, Data, and numeric precision separately; run platform validation on the real application bundle.
