When managing the company's old files, I encountered a bunch of Xls format form files. As the default format of Excel 2003 and previous versions, during the gradual update of subsequent versions of Office, it is very likely that problems such as inability to open, blocked functions or poor compatibility will occur. However, the new version of Xlsx format not only has smaller file volume, more powerful data processing ability, but also has higher security than the old version. Whether it is to improve our work efficiency or to save files for a long time, it is very necessary for us to batch convert the old Xls format to Xlsx format.

So apart from manually opening and saving one file at a time as Xlsx format, what else can we do to quickly convert the old version of Excel file into the new version of XLsx format for you. This text explains several methods from 0 to 1 to help you learn to convert Xls into Xlsx format in batches. Let's learn this technique to improve efficiency!

What do I need to batch convert multiple Xls to the new Xlsx format?

Software version compatibility

with the continuous change of some office software such as Office, many softwares have higher and higher requirements for file formats. The old version of Xls format cannot have larger data table capacity and some chart options. In this case, we can batch convert Xls files into Xlsx format with stronger compatibility, which is convenient for us to use smoothly in the new version of Excel and avoid data loss and format limitation caused by format problems.

Data sharing requirements

when the team handles a project together, it is best to use a common format for data files to share and collaborate. Xls files are not only large in size, but also have low compatibility, which is very easy to cause problems of slow loading and errors. However, Xlsx format can optimize the file size, speed up the loading speed, and enable all collaborators to view and edit files normally.

Long-term data preservation

when Excel forms are archived and stored for a long time, if they are in the old Xls format, they may be eliminated by the gradually updated software version in the future, resulting in the inability to open normally. Batch conversion to Xlsx format in advance can ensure that the files can still be opened and used in the next few years or more, so that Excel forms have better readability and usability.
