What Is an XLX File?

How to Open, Edit, and Convert XLX Files

XLX Files

A file with the XLX file extension is most likely associated with Xcelsius, as either a Crystal Reports file or an add-on file. Another way an XLX file may be used is as a XoloX Incomplete Download file that's used by the XoloX download manager.

XLX Files and Microsoft Excel

There's some confusion out there regarding XLX. While it might sound like a Microsoft Excel-based format, it's not. Microsoft Excel does not support XLX files and XLX files are not typical spreadsheet files.

Microsoft Excel is the primary program that supports XLSX files (the newer format) and XLS files (the older format), even though XLX looks an awful lot like those file extensions. Other formats used in Excel include XLK and XLL, but they too are different from XLX.

How to Open an XLX File

SAP Crystal Reports can open and work with XLX files that are Xcelsius Crystal Reports files. Crystal Xcelsius will work too and is most likely how XLX add-on files are used too.

XLX files that are XoloX Incomplete Download files probably can't be opened with the XoloX download manager because they are produced by the software and used only temporarily before being renamed with a new extension.

Use Notepad or another text editor to open the XLX file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with XLX files but it's worth a try.

If you find that an application on your PC does try to open the XLX file but it's the wrong application or if you would rather have another installed program open XLX files, see our guide for making that change in Windows.

How to Convert an XLX File

If you have an Xcelsius Crystal Reports file, you can most likely export it or save it as a new file format using the software I mentioned above. However, if the file is used as an add-on, like most add-on files, you probably can not convert it to any other format.

XoloX Incomplete Download files are a kind of tricky. Firstly, while it's true that you don't want to convert a partial file into any other format (because the whole file isn't there), a partial file may still function in some way.

However, this usually only works if the file is used in a start-to-finish manner like a document or a media file since they might still work if only part of the beginning is there and the rest hasn't downloaded.

For example, if you have an XLX file that you know is supposed to be a video file (like an MP4), it's possible that renaming the file from .XLX to .MP4 will let you watch as much of the video as is saved. This probably isn't ideal, but it may work if you need it to.

Another option for media files is to open the incomplete file in VLC, which is capable of playing most audio and video file formats and usually works just fine even if the whole file isn't there. In fact, you don't even need to rename the file if you use it with VLC (but you might need to drag it into the program window), which is especially helpful if you're not sure what the file extension should be.

Normally, a file conversion tool is necessary to convert a file from one format to another. However, because of the nature of how some download managers work (they attach a temporary file extension to the file during download), you might have success renaming the temporary file extension to whatever the program would rename it to once it's completed.
