Steps for Inserting Formulas in Excel using Node.js-based API

  1. Set up the Aspose.Cells Cloud API client using CellsApi with your credentials with Client ID, Client Secret, and Base URL
  2. Specify the name of the Excel file that will be processed
  3. Prepare a request to upload the local Excel file to Aspose’s cloud environment and execute the upload
  4. Create a request to insert a formula =NOW() with the PostWorksheetCellSetValue() method into a specified cell D1 in a particular worksheet of the uploaded file
  5. Request to download the updated Excel file from cloud storage
  6. Write the downloaded file stream to a local file
  7. Wrap the entire process in a try-catch block to handle and report any exceptions that may occur during execution

These steps express how to insert a formula in Excel using Node.js-based API. The program authenticates with Aspose.Cells Cloud, uploads an Excel file, inserts a formula (=NOW()) into a specific cell on a worksheet, and downloads the updated file. It handles any exceptions during the process and saves the final file locally.
