Since you couldn’t find any component on marketplace & UiPath does not support Microsoft Access databases natively through its database activities, you can consider the following workaround:
Use the OLE DB provider for Microsoft Access to connect to the database and execute SQL commands.
Export the data from Microsoft Access to a supported database engine, such as Microsoft SQL Server or MySQL, and then use the UiPath.Database.Activities package to interact with the exported data.
Use a third-party connector that provides support for Microsoft Access databases, such as the Jet.OLEDB provider or the System.Data.Odbc namespace.

However, I am currently stuck at converting the CSV files to .txt file. How do I read an entire workbook, save to data table and save as .txt?
