Here’s how to convert an older .doc .xls or .ppt into a safer and smaller .docx .xlsx .pptx even if you don’t have Microsoft Office.
Any smart computer user is wary of documents received in the old .doc .xls .ppt formats because they are regularly used to transmit viruses. The new document formats are much safer.
Office for Windows or Mac
Office 2007 and later for Windows plus Office 2011/2016 for Mac can open the old formats and ‘Save As …’ to the new equivalents.
Even if you don’t have that software, it’s easy, cheap and secure to convert older documents to the new format. Over the decade since the ‘new’ formats arrived, there are even more options available.
There’s are enough free conversion options from Microsoft that third-party options should not be necessary.
Office compatibility pack
The ‘Office compatibility pack’ is for Office 2000, Office XP and Office 2003. Install the free download from Microsoft then you can read and save documents in the newer formats created after the original software was released.
Office Mobile apps in Windows 10
If you have Windows 10, the free Word Mobile, Excel Mobile and PowerPoint Mobile apps (available from the Microsoft Store) can open the older documents so you can save them to the new formats.
Office Mobile apps for Apple or Android devices
Similarly, the Word, Excel and PowerPoint apps for Apple iPhone and iPad or Android devices can open the older file formats but not save to them. Open an older document then ‘Save As …’ to a recent document type.
The web based versions of Word, Excel or PowerPoint can also read the older formats and save to the newer ones.
