XLSX converter
Convert your XLSX files to any format.
What is a XLSX file?
XLSX is the standard spreadsheet format — rows, columns, formulas and charts in a file every version of Excel and most office suites can open and edit.
First released in 2007 by Microsoft, it uses lossless compression and no transparency, which makes it best suited to editable spreadsheets, data tables and financial reports compatible with Microsoft Excel.

Advantages of the XLSX format
Fully editable data
Unlike PDF, XLSX keeps all rows, columns, formulas and formatting intact and editable in any spreadsheet application.
Universal spreadsheet compatibility
XLSX is the default format for Microsoft Excel and is supported by Google Sheets, LibreOffice Calc, Apple Numbers and virtually every other spreadsheet tool.
Formulas and calculations preserved
Unlike a PDF snapshot, an XLSX file keeps live formulas, named ranges and charts that recalculate as data changes.
