Convert DEX to XLSX

Understanding DEX and XLSX file formats

DEX files, short for Dalvik Executable, are used by Android applications to store compiled code that runs on the Dalvik Virtual Machine. These files are not designed for tabular data or spreadsheet use, but rather for executing application logic on Android devices.

XLSX is the standard file format for Microsoft Excel spreadsheets. It stores data in a structured, tabular form and supports features like formulas, charts, and formatting, making it ideal for data analysis and reporting.

Why convert DEX to XLSX?

Converting a DEX file to XLSX is an uncommon process, typically required when you need to extract specific information (such as method lists, class names, or other metadata) from an Android application for analysis or documentation in a spreadsheet format.

How to convert DEX to XLSX

Since DEX files are not natively compatible with spreadsheet software, the conversion involves two main steps:

1. Extract data from the DEX file: Use a DEX decompiler or parser (such as JADX or dex2jar) to extract readable information from the DEX file. Export the relevant data (e.g., class names, methods) to a text or CSV file.
2. Convert extracted data to XLSX: Open the exported CSV or text file in Microsoft Excel or LibreOffice Calc, then save or export the file as XLSX using File → Save As or File → Export.

Recommended software for DEX to XLSX conversion

• JADX: A powerful open-source DEX decompiler that can export class and method lists to text or CSV.
• dex2jar: Converts DEX files to JAR, which can then be analyzed with Java decompilers to extract data.
• Microsoft Excel: For importing CSV or text data and saving as XLSX.
• LibreOffice Calc: A free alternative to Excel for handling CSV and XLSX files.

Step-by-step example using JADX and Excel

1. Open your DEX file in JADX.
2. Export the class/method list to a CSV file.
3. Open the CSV file in Microsoft Excel.
4. Go to File → Save As and choose XLSX as the file format.

By following these steps, you can efficiently convert DEX file data into an XLSX spreadsheet for further analysis or reporting.
