--excel (-e)

If not indicated, the tool limits its search to plain text files, but by using this flag we will include Excel files to search for possible PAN values inside them.

The extensions it can handle are: .xlsx, .xlam, .xlsm, .xltm, .xltx

In case some possible PANs are found, the result will be: Sheet name Cell reference Cell value PAN Brand BIN length PAN length Confidence level Position inside the text where the value was found

There is a max size of Excel files that can be processed, which is by default 10Mb, but that value can be changed using the flag --xsize. This is because the library we use to open the Excel files requires a lot of memory and time to perform the search inside those files. That is why we limit the search inside Excel files to relatively small files.

Processing Excel files in implicit when using the --massive flag.
