How to read the Excel file through Azure data factory for limited columns data but number of rows are uncertain

Question

Using Azure data factory, I am trying to read the excel file for the column A to F but number of rows are changing every time. Please help me to define the range dynamically.

Working case : If I give the column range as A1:F9999 it is reading the data specified range.

Not working case: If I give as A1: ( as suggested by microsoft doc) to read all the column and rows from excel, it is not working throwing a below error

"Invalid excel cell range 'A1:' with error 'Index was outside the bounds of the array.'. Index was outside the bounds of the array."

Please help me with any leads

Answer 1

Thank You @Nandan for your suggestion- We have tested in our environment;

Give only A1 in range it scans a table beginning with the specified cell A1 , dynamically detecting all the rows below it and all the columns to the right of it.

If you want specific range of columns, you must have to mention that.

Answer 2

is your issue fixed? I am facing the same issue. After changing the range to A5, it can't find the first row as header.

ErrorCode=ExcelInvalidHeader,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Invalid excel header with empty value.,Source=Microsoft.DataTransfer.ClientLibrary,'
