ExcelScript Type Definnitions

Question

Really sorry if this has been answered somewhere… Does anyone know if a @types/ npm library exists for ExcelScript? Or even an ExcelScript.d.ts file somewhere?

Answer 1

The type definitions for Office Scripts are not open source. A copy of those definitions is used to generate the reference documentation. It is updated shortly after the internal definitions are updated. You can find a public copy of the .d.ts file here: https://github.com/OfficeDev/office-scripts-docs-reference/blob/main/generate-docs/script-inputs/excel.d.ts
