Silent failure of JSON-LD export on some Macs

[mrgarth]

Alana observed that the file export dialogue completes with a "success" message, but no file is created. Her environment: M2 chip, Excel 16.105.3 (26020123), MacOS 14.5 (23F79).

I was unable to reproduce the issue on my environment: Intel i7 chip, Excel 16.106.3 (26030211), MacOS 15.4.1 (24E263).

Alana updating Excel and running Excel with Rosetta did not change the results.

After some digging around in CoPilot my best guess is:

• that the JSON‑LD export is blocked on some, but not all, Macs because the file download is triggered after async operations and dialog callbacks, not directly from a user click. macOS Excel (WKWebView) silently suppresses non‑gesture‑initiated downloads; this is expected platform behaviour. The export must be triggered directly by a click (or via Office dialog API) to be reliable.

I'm on it.

Alana shared that Derron also experienced the same issue as her; his environment specs:
Excel: Version 16.107.3 (26032814)
Mac OS version: Sonoma 14.3.1
