Types of Data Encoded in Base64

Within an application I am developing, there is a feature for downloading files that are stored as Base64 strings. It is essential to correctly pair the data types with the corresponding files in order to ensure successful downloads.

I thought I had sorted this out quite well. However, it appears that docx files are being downloaded as doc files and xlsx files as xls files. Is there a way to download these files in their proper file formats? Unfortunately, most of the websites that provide information on this topic are restricted by company policies.

For docx files, I currently have data:application/msword

and for xlsx files, I have data:application/vnd.ms-excel

Answer №1

When dealing with .xlst files, the correct MIME Type is: 

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

For .docx files, use the following MIME Type: 

application/vnd.openxmlformats-officedocument.wordprocessingml.document

To learn more about the correct content-type for excel files, check out this helpful resource: What is correct content-type for excel files?
