Data Truncation issue while importing excel from Azure Blob storage to Sql Server

Question

I'm trying to import the below excel file present in the azure blob storage into sql server

EXCEL File

Query

SELECT * 
    FROM OPENROWSET(
        BULK 'container/testfile.xlsx', 
        DATA_SOURCE = 'ExternalSrcImport',
        FORMATFILE='container/test.fmt', FORMATFILE_DATA_SOURCE = 'ExternalSrcImport',
        codepage = 1252,
        FIRSTROW = 1
        ) as data

Format file

10.0  
4  
1       SQLCHAR       0       7       "\t"     1     DepartmentID     ""  
2       SQLCHAR       0       100     "\t"     2     Name             SQL_Latin1_General_CP1_CI_AS  
3       SQLCHAR       0       100     "\t"     3     GroupName        SQL_Latin1_General_CP1_CI_AS  
4       SQLCHAR       0       24      "\r\n"   4     ModifiedDate     ""  

Illustration of Format File

when I execute the query, I'm getting the below error

Msg 4863, Level 16, State 1, Line 210 Bulk load data conversion error (truncation) for row 1, column 1 (DepartmentID).

looks like field terminator in the format file is not working, any ideas to import the file ?

Answer 1

Your format file is representing import of a tab separated values file, but in the source path you are referring to an xslx file.
Xslx file is an ZIP archive of multiple XML files, bulk import will not be able to process it. To open it you need to use Microsoft Jet or ACE driver, you have some examples here: using-openrowset-to-read-excel . You will need to download file from blob storage to local disks before processing it. You can use SQL Agent or SSIS to download it.

Other option will be to save your data as CSV or tab separated file and load it directly from blob storage.
