Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=56914
A full implementation should ideally use a JSON library.
-- v2: windows.web/tests: Add IJsonValueStatics::Parse() tests. windows.web: Implement IJsonValue::GetBoolean(). windows.web: Implement IJsonValue::GetNumber(). windows.web: Implement IJsonValue::GetString(). windows.web: Add error handling in IJsonValue::GetObject(). windows.web: Add error handling in IJsonValue::GetArray(). windows.web: Partially implement IJsonValueStatics::Parse().

You're leaking some references here, I think you don't need the last `WindowsDuplicateString` and this should work as well:
``` HSTRING pattern = NULL, new_string = NULL; HRESULT hr = WindowsCreateString( string_to_remove, wcslen( string_to_remove ), &pattern );
if (SUCCEEDED(hr)) hr = WindowsTrimStringStart( input, pattern, &new_string ); if (SUCCEEDED(hr)) hr = WindowsTrimStringEnd( new_string, pattern, trimmed_string );
WindowsDeleteString( pattern ); WindowsDeleteString( tmp ); return hr; ```

Although it probably works in all cases, trimming the quotes seem specific to string values and IMO should be done in the string-specific case above.

It does indeed some validation for array and objects but otherwise it also actually parses the json and extract the values. What about naming it `parse_json_value` and let it accept a `struct json_value *` directly?
I think you could then later implement object and array parsing easily by calling `IJsonValueStatics_Parse` recursively.

- for ( int i = 0; json[i] != '\0'; i++ )
- {
char c = json[i];
Unless it is important to validate the strings I would leave this for later, and return S_OK. Validation is also just a matter of actually parsing the array and objects, so implementing them would automatically end up validating the json string.

Is the string guaranteed to be 0 terminated? You should probably check that length is the expected string length and use `wcsncmp` for comparison, here and everywhere below. For `wcstod` you can perhaps use `wcstold` or make a copy.
It would be more robust for later if we want to optimize things later and avoid too many allocations, by parsing the whole string in place.
Regarding using a library, I would have considered adding cJSON to libs/ but we actually need to parse WCHAR strings, which it doesn't do. And JSON should hopefully be simple enough to implement our own parser.
