This API is used for converting an sheet in an excel file into an JSON object.
The API comes with Swagger, but since Swagger doesn't support multipart and file upload, I recommend testing this API with Postman.
This repo contains an excel test file.
You can use this file with the following parameters:

ExcelConfig = [{"ColName": "test1", "ColIndex": 0}, {"ColName": "test2", "ColIndex": 1}, {"ColName": "test3", "ColIndex": 2}, {"ColName": "test4", "ColIndex": 3}]
ExcelSheetName = test
