Hi @Divya Charita ,
Thank you for posting query in Microsoft Q&A Platform.
You can consider using Synapse or ADF for ETL purpose to take data from different sources to your Datawarehouse. Once data loaded to Datawarehouse you can initiate tabular model data injection process. Synapse pipelines and ADF supports excel format data.
Please let us know if it helps. If my understanding of your ask is incorrect then could you please share more details about query may be with sample example scenario? so that its more easy to share thoughts. Thank you.
