How can we use the facility of Bulk Generation?

You will need to create the e-way bills requests via JSON file in order to use the bulk generation facility. You can do  using anyone from of two ways. A registered taxpayer, or a transporter, can create the JSON file from his automated system. He can also use the portal's excel-based bulk generator tool. You can generate a JSON file by entering the invoice and other details. The JSON file must be uploaded to the portal in order to generate multiple e-Way invoices. Please refer to the EWB portal's tool section for more information.
