What is a ._XLSX file?
An ._XLSX file is essentially a Microsoft Excel spreadsheet file that originally had a .XLSX extension. This extension might have been changed to ._XLSX either intentionally or by mistake. This could be due to a user renaming the file to differentiate it or by an error in transferring or saving the file.
To use this file as a normal Excel spreadsheet, you first need to change its extension back to .xlsx. This is because most software, including Microsoft Excel, recognizes the .xlsx extension for opening and editing Excel files.
Once you have renamed the file to end with .xlsx, you can open it using various programs depending on your device: - On a computer with Windows or macOS, you can use Microsoft Excel. - On mobile devices like iPhones (iOS) or Android phones, you can use respective apps that support Excel files, such as Microsoft Excel for mobile. - On Chrome OS devices, you can use Google Sheets or Microsoft Excel through the web or app.
Remember, until you rename the file to .xlsx, most programs will not recognize it as a valid Excel file and will not open it.
