Hi techlandandyzhang,
We have validated your reported query based on the shared
details and screenshot. And we would like to let you know that currently
Spreadsheet don’t have support to accept asynchronous function as custom
formula function.
However, we have already considered this is an improvement
and logged it as a feature. It will be available in any of our upcoming
releases. You can communicate and track the status of the feature using the
below link from our feedback portal.
Feedback link for tracking purposes: https://www.syncfusion.com/feedback/39730/provide-support-to-accept-asynchronous-function-as-custom-formula-function
At the
planning stage for every release cycle, we review all the open features once
again and finalize features for implementation based on specific parameters
including product vision, technological feasibility, and customer interest.
Once we have anything definite to share about these features implementation, we
will move the feedback to scheduled status with the tentative release timeline.
We appreciate your patience until then.
