This brief tutorial will provide the details on how to convert CSV to Excel in Java. We will use the Workbook class object for loading the input file along with the newly created LoadOptions object. During this operation, using Java convert CSV to Excel and then save the converted file as an XLSX file.

Steps to Convert CSV to Excel in Java

1. Using Maven repository, add Aspose.Cells library to the application to convert CSV to Excel
2. Initialize LoadOptions class instance to load the input CSV file
3. Create a Workbook class instance with the input CSV file path and the LoadOptions object
4. Save the converted XLSX workbook output file

These basic steps show how simple it is to convert CSV to XLSX in Java where you can load the source CSV file with comma-separated values. The conversion is efficient enough that it consumes a little time and CPU resources for creating the output XLSX file. This conversion is useful to perform calculations on numeric values from a CSV file because Excel files are commonly used to perform mathematical calculations.
