Answer 1

There is not a built-in way to extract from excel file in Azure data lake. I would suggest you to try one of the below approaches:

• Write Custom .NET library for converting Excel to CSV and deploy that to Azure Data Lake Analytics. Azure Data Lake Analytics Programming Guide

• Write a custom .NET activity in Azure Data Factory to do this. Custom Activities in Azure Data Factory

• Use Azure Functions and Open XML do this activity as detailed in the stack overflow post

• Use SSIS Package to do the conversion. You can have SSIS Runtimes in Azure Data Factory. SSIS packages running in Azure Data Factory

Answer 2

As I know about Azure, These isn't any way can help convert the excel file to csv directly.

You could follow these steps:

1. Download the excel file to you computer.

2. Import the excel file to the you SQL database.

3. Then export the table data as CSV file to you Blob Storage.

You could reference this document:

1. Import data from Excel to SQL Server or Azure SQL Database
2. Connect to Azure Blob Storage (SQL Server Import and Export Wizard)

Hope this helps.
