Hi @Anoshpananda,

Base64 to String – gab1one

Hello @Anoshpananda,

@Anoshpananda

which extension needs to be installed for files to base64 component?

Components are not obtained from extensions but from KNIME Hub. You can either do Drag&Drop or (new option from within couple of days) simply download. (Check picture bottom.) If component uses node from extension you don’t have installed then you should get prompted to install it.
