Convert Excel to HTML using cURL Commands

Converting Excel to HTML / XLS to Web using REST API and cURL commands offers a number of benefits. First and foremost, this approach is highly flexible and can be easily integrated into your existing workflows. By using REST API and cURL commands, you can automate your document conversion tasks and reduce the amount of time and resources required for manual conversion. Additionally, using a cloud-based tool like Aspose.Cells Cloud enables you to perform conversions on a scalable and secure platform, without the need for any additional software. Lastly, using REST API and cURL commands for converting Excel to HTML is a cost-effective solution that can help you save money on licensing fees and maintenance costs.

So first we need to generate a JWT access token while executing the following command.

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 we have the JWT token, we need to execute the following command to convert XLS to HTML and save the output in Cloud storage.

curl -v -X PUT "https://api.aspose.cloud/v3.0/cells/convert?format=HTML&outPath=converted.html&checkExcelRestriction=true" \
-H  "accept: multipart/form-data" \
-H  "authorization: Bearer <JWT Token>" \
-H  "Content-Type: multipart/form-data" \
-d {"File":{}}
