XLSB to PDF using cURL Commands

In this section, we are going to use cURL commands to load XLSB from cloud storage and convert it to PDF format. So as a pre-requisite, we need to first generate a JWT access token based on client credentials.

curl -v "https://api.aspose.cloud/connect/token" \
-d "grant_type=client_credentials&client_id=bbf94a2c-6d7e-4020-b4d2-b9809741374e&client_secret=1c9379bb7d701c26cc87e741a29987bb" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Once the JWT token is generated, please execute the following command to perform the conversion.

curl -v -X GET "https://api.aspose.cloud/v3.0/cells/input.xlsb?format=PDF&isAutoFit=false&onlySaveTable=false&outPath=Converted.pdf&checkExcelRestriction=true" \
-H  "accept: application/json" \
-H  "authorization: Bearer <JWT Token>"
