How to load excels sheet with different schema into cosmos DB using ADF

Sivanesan S 21

I am trying to load some excel files with same sheet name but with different schemas from Azure blob storage to Azure CosmosDB using ADF. I have created the pipeline using wildcard source path. But while trying to preview the data its throwing an error saying that load excel with different schema is not supported now
Can anyone suggest how to proceed further.

Hi @HimanshuSinha-msft ,

Thanks for reaching out. Sorry I wasn't able to get back as I got side tracked with other items. Before using for each activity I wanted to import each file manually and check. But while previewing the data all excels are getting pulled with a blank row at the top. And in one excels its just pulling only the blank row not the data row. can you help with why this is happening.

Thanks

Hi @HimanshuSinha-msft ,
Thanks for getting back on this.. I guess the issue is happening because of the formatting issue in the excels. Earlier I was trying to copy the data using data flow activity during when I got NULL records inserted into the table. When I tried to copy the same data using copy activity the data got inserted without any NULLs which seems to be weird.

Thanks

Hi @Sivanesan S , Generally, we use Lookup/ GetMetaData activity depending upon the requirement to read through the source and pass the output to ForEach activity which iterate through one by one and subsequently passed to copy activity to copy the data in to the sink.

Below links further helps you to understand it. Thanks
