To use the bulk generation facility, one has to prepare the e-way bill requests through JSON file. This can be done in two ways – registered taxpayer or transporter can prepare the JSON file directly from his automated system. If he is unable do so, he can use excel based bulk generation tool available on the portal. The invoice and other details need to entered as per the format and JSON file can be generated. This JSON file need to be uploaded in the portal for generation of multiple e-Way bills. For more details, please refer to the ‘user manual of the bulk generation’ and ‘bulk generation tools’ under tool section at EWB portal and follow the instructions.
