Documents in the XLSB format are binary files of a spreadsheet , generated by the Microsoft Excel 2007 program or newer. XLSB files contain data of a spreadsheet, which is a collection of cells based on the structure of columns and lines.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the XLSMHTML file after converting to XLSB may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from XLSMHTML to XLSB to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting XLSMHTML to XLSB does not meet your expectations, you can simply try to find on the Internet a different version of your file in XLSMHTML format, properly converted to a XLSB file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file XLSMHTML the desired result was not achieved, you can try to change the format of XLSMHTML file to other than XLSB. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your XLSMHTML file converted by someone else, and the attempt to convert it to XLSB on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the XLSMHTML file in its original format (without conversion to XLSB file). Such a solution will be difficult to implement, but it certainly will give the best result.
