Convert TXT to CSV in Java

TXT files often contain raw numeric or textual data that must be imported into spreadsheets or databases. Converting these files to CSV (Comma Separated Values) makes the data instantly usable in Excel, Power BI, and many other tools. This article explains how to perform a TXT‑to‑CSV conversion in Java using the Aspose.Cells library, complete with installation steps and a ready‑to‑run code example.

Convert TXT to CSV File in Java

Follow these three simple steps to transform a TXT file into a CSV file:

  1. Create a TxtLoadOptions object – configure any parsing options such as delimiter or encoding.
  2. Load the TXT file using the Workbook class, which treats the text data as a worksheet.
  3. Save the workbook as a CSV file to the desired output location.

The code snippet below demonstrates the complete process. It reads a tab‑delimited TXT file and writes a standard CSV file.
