Use Aspose.Cells Cloud SDKs

Using an SDK is the best way to speed up development. An SDK handles low‑level details and lets you focus on your project tasks. Please check out the GitHub repository for a complete list of Aspose.Cells Cloud SDKs.

Notes

The API can unlock multiple Excel files in a single request; each file is returned in the Files array of the response.
Ensure your SDK version matches the API version (v3.0) to avoid compatibility issues.
