XLS and XLSX files
XLSX and XLS files are Microsoft Excel Spreadsheets commonly used to store financial data and to create mathematical models. These files store data in worksheets that contain cells arranged as a grid of rows and columns. Excel spreadsheets may also contain charts, mathematical functions, and various kinds of cell formatting. Spreadsheets are often used in business contexts to store financial data and to perform mathematical computations.
There are differences in the XLSX and XLS formats created by Excel. While XLS files use a proprietary binary format, XLSX files use a newer file format referred to as Open XML. The XLS extension is used by Microsoft Excel 2003 and earlier and the XLSX extension is used by Microsoft Excel 2007 and later.

Possible causes that documents do not save
Select the tab that applies to you, or go to the Quick resolution section below.
If the Excel file is not saved when you run Excel in Windows safe mode, the issue may be caused by a third-party add-in or by a file that is in one of the Excel startup locations. By default, these files are loaded when you start Excel.
Sometimes, third-party software vendors install custom add-ins to work with Excel. Some of these add-ins work with existing Excel features by design, and some are intended to enable a seamless transition when you are using a third-party product. Typically, these third-party add-ins do not interfere with normal Excel functionality. However, there are some exceptions. For example, Excel save conflicts have occurred because of an add-in.
To test for and eliminate the possibility that a third-party Excel add-in or file is causing an Excel save issue, start Excel in safe mode. To do this, follow these steps:
Exit Excel.
Select Start, and then point to Programs.
Press Ctrl when you start Excel, and hold it until you receive a message that resembles the following:
Excel has detected that you are holding down the Ctrl key. Do you want to start Excel in safe mode?
Select Yes.
Try to save a new Excel file, and then resave the same Excel file again.
If the file saves correctly, a custom add-in or a file that is located in an Excel startup location is most likely the cause. You must locate and remove the add-in or the file to eliminate the problem. After you determine the add-in or the file that caused the problem, contact the vendor that designed it. The vendor may have additional information about this issue and an update that does not cause the issue to occur.

For more information about how to determine the folders that Excel uses during startup and additional options to disable this functionality, see the following articles:
When you save an Excel file, you must have the following permissions to the folder in which you are saving the file:
- Read permission
- Write permission
- Modify permission
- Delete permission
Note
If you do not have these permissions, the Excel save process cannot be completed.
When you save to any medium, such as a hard drive, an external storage drive, or a network drive, you must make sure that the drive has sufficient free space to enable the file to save. If the destination drive does not have sufficient space, Excel cannot complete the save operation, and you receive the following error message:
Disk is Full.
For more information about this error message, see the following articles:
When antivirus software is installed or is running, you may receive an error message when you try to save an existing workbook. You do not receive an error message if you try to save a new file. You may receive an error message because some antivirus programs quickly scan any new files that appear on a computer. This scan can sometimes disrupt the Excel save process. This interruption may stop Excel from saving the file correctly.
To check if your antivirus software conflicts with Excel, temporarily deactivate the antivirus software and then try to save the Excel file.
If you and a second user work concurrently on a shared workbook, you may receive an error message if you and the second user try to save the file at the same time. You receive an error message because Excel cannot save the file if another instance of Excel is saving the same file.
For more information about this error message, see Unlock a file that has been locked for editing.
If you try to save or open an Excel file, and the path of that file (including the file name) is more than 218 characters, you may receive the following error message:
Filename is not valid.
For more information, see Error message when you open or save a file in Microsoft Excel: 'Filename is not valid'.
Process to save a file
Excel follows these steps when it saves a file:
- Excel creates a randomly named temporary file (for example, Cedd4100 without a file name extension) in the destination folder that you specified in the Save As dialog box. The whole workbook is written to the temporary file.
- If changes are being saved to an existing file, Excel deletes the original file.
- Excel renames the temporary file. Excel gives the temporary file the file name that you specified (such as Book1.xls) in the Save As dialog box.
Virtual window for office. For more information, see Description of the way that Excel saves files.
Note
Other processes that occur on your computer may disrupt the Excel save process. These issues may occur if the Excel temporary file is accessed before the Excel save process is completed. For example, the local antivirus software locks the temporary file for scanning before the file can be renamed. Therefore, you must keep track of any new software installations or updates that are performed before you have problems when you try to save workbooks. This information will be helpful if this article does not fix your issue and you have to contact Microsoft Support.
