everyone, I'm handling some paragraphs enconded with Base64 from CSV file format. The problem is that Mathematica can't decode it. It seems Mathematica Encode/Decode their own Base64. I'm thinking write my decode method by my own, but I ask it first. By example:

I used base64.b64encode on python with the string:

s = '"Hola los felicito por su equipo de comunicadores. Me encanta verlos pues ustedes se salen de las   simplezas y superficialidades de los noticieros tradicionales.Un saludo desde Montreal- Canada.

Adelante! así como van en poco tiempo tendrán muchos mas seguidores que  la ""Gran prensa Colombiana"" la cual ha venido mintiendo por décadas.

"'

And outcome:

 b = 'IkhvbGEgbG9zIGZlbGljaXRvIHBvciBzdSBlcXVpcG8gZGUgY29tdW5pY2Fkb3Jlcy4gT\
WUgZW5jYW50YSB2ZXJsb3MgcHVlcyB1c3RlZGVzIHNlIHNhbGVuIGRlIGxhcyAgIHNpbXB\
sZXphcyB5IHN1cGVyZmljaWFsaWRhZGVzIGRlIGxvcyBub3RpY2llcm9zIHRyYWRpY2lvb\

But if you use another base64 decoder like decoderb64, it can do the job.

Thanks in advance,

That's because "Base64" is not a format but an encoding and you still need to tell Mathematica what format to import after decoding from Base64. This is described in the documentation.

Try this:

ImportString[s, {"Base64", "String"}]

Oh, Thanks, I don't figure out. I thought that "String" was implicit. –  d555 Apr 3 at 14:45
    
@d555 It could be anything, not just String. Base64 is considered an encoding just like gzip (which is also supported). Any file in any format can be encoded like this. –  Szabolcs Apr 3 at 14:50
