This tutorial demonstrates how to import data into Excel using the Java REST API. Leveraging the Java‑based Aspose.Cells Cloud SDK, you’ll learn to transfer lists or arrays from your program straight into an Excel workbook and precisely define the destination cells for the imported data.

Prerequisite

• Create an account and get API credentials for inserting double array data into an Excel file
• Download Aspose.Cells Cloud SDK for Java to import lists or arrays of numbers to Excel
• Set up a Java project with the above SDK

Steps for Data Import to Excel using Java Low Code API

1. Set your client ID, client secret, and base URL to connect to Aspose.Cells Cloud
2. Set up the CellsApi object with your credentials for API operations
3. Specify the local Excel file that you want to upload and update
4. Create an upload request with the file details and send it to Aspose Cloud storage
5. Set up the import options to define where and how the double array will be inserted into the worksheet
6. Create and execute the PostImportData call to insert the double array data into your specified worksheet
7. Request and download the modified Excel file from the cloud to your system and save it on the disk

These steps summarize the process of data import in Excel using Java-based API. First, you connect to Aspose Cloud, upload your Excel file, and set up how and where your double array data should be added. Once the data is imported using the PostImportData API call, simply download the updated file and save it to your computer.

Code to Automatically Import Data into Excel using Java RESTful Service

With the code above, you’ve seen how to import data into an Excel spreadsheet through the Java REST Interface. You can choose the target worksheet, define the starting cell, specify the import data type, and set the orientation—horizontal or vertical. Remember, the IsInsert flag must be set to actually insert the data into the sheet.

In this tutorial we explored how to programmatically import a list or array into an Excel workbook using the Java REST interface. If you need to bring CSV data into XLSX, check out our guide Import CSV to XLSX using Java REST API.
