To use the Bulk generation facility, one must prepare the IRN requests through a JSON file. Can do this in two ways – registered taxpayers can prepare the JSON file directly from their automated system. If he is unable to do so, he can use excel based Bulk generation tools available on the e-invoice portal.
The invoice and other details must be entered as the format and generated in a JSON file. Must upload this JSON file to the e-invoice portal to generate multiple IRNs. For more details, please refer to the ‘user manual of the bulk generation’ and ‘bulk generation tools’ under the “Tools” section at the E-invoice portal and follow the instructions.
