I need an idea of ​​how to make an architecture in Azure

You may consider this:

1. Azure Blob Storage or Data Lake Storage

• Use Azure Data Lake Storage Gen2 to store the uploaded Excel files. This will act as the central repository for your raw data.

2. Azure Logic Apps or Azure Functions

• Set up an Azure Logic App or Azure Function to trigger whenever a new file is uploaded to the storage.
• The trigger can initiate the process of converting the Excel file to CSV.

3. Excel to CSV Conversion

• Use Azure Functions with a script (e.g., Python or .NET) to read the Excel file and convert it to CSV. Libraries like pandas (Python) or EPPlus (.NET) can handle this conversion efficiently.

4. Automated Workflow

• Once the file is converted, save the CSV file back to the same or a different folder in the Data Lake.

5. Monitoring and Logging

• Implement monitoring using Azure Monitor or Application Insights to track the success or failure of the process.
• Log all activities for debugging and auditing purposes.

6. Optional Enhancements

• Use Azure Data Factory for more complex workflows, such as integrating with other data sources or performing additional transformations.
• Add Azure Key Vault to securely manage any credentials or secrets required for the process.
