This brief topic encompasses how to convert TSV to Excel in Node.js by illustrating all the details to configure your development environment, detailed programming steps to develop this application, and a working sample that exhibits this feature. Although a fairly simple example is presented here, however, you can further customize the TSV file loading process as well as the saving of the generated Excel file as an XLSX, XLS, XLSM, or any other supported format on the disk. You can implement the stated process to transform TSV to Excel in Node.js in any operating system supporting Node.js, like MS Windows, Linux, and macOS.

Steps to Convert TSV to Excel in Node.js

1. Set the environment to use Aspose.Cells for Node.js via Java to convert TSV to XLSX
2. Set the source file format that is required to be loaded for the conversion using the LoadOptions class instance
3. Load the source TSV file using an instance of the Workbook class using the above format and other settings
4. Save the exported Excel file as an XLSX converted from TSV

The above-stated steps lead to creating an application an application for exporting TSV file to Excel in Node.js. In order to serve the purpose, the configuration steps are elaborated that are required to generate this program, and finally, in the end, you will get a runnable example code that can be utilized without relying on any other third-party tool for creating the XLSX file.

Code to Export TSV to XLSX in Node.js

This example code transforms a source file in the TSV format to Excel in Node.js by specifying its load format. One may also set other optional properties before loading the source TSV file, including a standard font, setting warning callbacks in case of any error, regional configurations, and checking data validation, to name a few. This code example demonstrates a straightforward process whereby TSV file is loaded and exported as an XLSX file, however, you can also perform other advanced operations on the generated Excel file including setting password security.

We have learned how to write a TSV to Excel converter in Node.js using a simple API interface. If you want to learn about creating an Excel chart against the TSV data before generating the output Excel file, refer to the article on how to create Excel chart in Node.js.
