Convert Base64 Strings to Numbers

Hallo everyone,

I currently have data in columns in Base64 format and I want to decode it with KNIME into “real” numbers. Is there a way to do it in KNIME? I already tried the “Base64 to String”-Node, but this only returns empty cells.

Thank you in advance"

Hello @needknimehelp,

there are Base64 Encoder & Decoder nodes available in Palladian extension. Maybe they’ll work for you.

thank you for your answer. Unfortunately Iam not allowed to install external packages like that

thank you for your answer aswell. I can not use that Node since I can not update KNIME to the newest version.

Does anyone maybe have a solution for Java snippet node?
