With Version 3.8.2 there are Types in die index.d.ts file, which have not been defined.
Lib version: 3.8.2

node_modules/exceljs/index.d.ts(1319,47): error TS2304: Cannot find name 'HeaderArray'.

node_modules/exceljs/index.d.ts(1346,13): error TS2304: Cannot find name 'RowTransformFunction'.
no Typescript errors
type definitions
for now, I recommend use version 3.8.1
