XML to XLSX Converter
The easiest way to restore legacy XML Spreadsheets to modern Excel files. Do you have old "XML Spreadsheet 2003" files that modern apps won't open? This extension allows you to convert legacy .xml data into clean, native Microsoft Excel .xlsx files with a single click. No more messing with "Text Import Wizards" or broken CSV formatting.
🚀 Why Choose XLSX over CSV?
Preserve Data Integrity: No more "broken" columns or special character errors often found in CSVs.
Native Compatibility: The output is a true OpenXML file (.xlsx) compatible with Microsoft Excel, Google Sheets, and LibreOffice.
No Formatting Hassles: Dates, numbers, and text stay in their proper cells automatically.
