If you’re not using Chrome, you can still open and edit XLS files exclusively online with the free Zoho Sheet tool. You don’t even need a user account to work with XLS files at Zoho — you can upload the file to the website and start making changes immediately. It supports saving back to an online account or to your computer in a number of formats, including back to XLS.
DocsPal is another free XLS viewer that’s purely a viewer, not an editor. Since it runs online without needing any installation, it works in all browsers and operating systems.
Note: Is your XLS file still unable to open properly? Be sure that you’re reading the file extension incorrectly and not confusing an XSL or XSLT file with an XLS file.
XLS File,How to Convert an XLS File
If you’re already using one of the spreadsheet programs we’ve already mentioned, converting is easiest via opening the XLS in that program and then saving it to a different format. This is by the far the fastest way to convert XLS files to other formats like CSV, PDF, XPS, XML, TXT, XLSX, PRN, and other similar formats.
If you don’t have an XLS editor installed, or don’t want to install one, using a free document converter is another option. Zamzar is one example of a free online XLS converter that converts XLS to MDB, ODS, and others including image formats like JPG and PNG.
If your XLS has data that you need in an open, structured format, the Mr. Data Converter online tool is a great option, converting XLS or CSV directly to XML, JSON, or a number of other similar formats.
How to Crack an XLS Password or Unlock an XLS
XLS files can easily be password protected using a program like Excel. You can also use the same program to remove the password. However, what do you do if you’ve forgotten the password to your file?
A free password recovery tool can be used to unlock an XLS file that’s been protected with a “password to open” password. One free tool you can try that should find the password to an XLS is the free Word and Excel password recovery wizard.
Although not free, Excel Password Recovery Lastic is another option.
