How to base64 decode

Base64 is a binary to text encoding that allows you to represent binary data as ASCII text. It is widely used to store images and other binary data within text based formats.

You can easily decode base64 data with Easy Data Transform:

• Install Easy Data Transform on your PC or Mac, if you haven’t done so already. It will only take a minute. There is a fully functional free trial and you don’t have to give us your email or sign up to anything.
• Start Easy Data Transform. Make sure the Auto Run button is pressed in.

• Drag the file containing the base64 encoded data onto Easy Data Transform. The file can be CSV, Excel, XML, JSON, fixed column width or vCard format. A pink input item will be added.
• In the Right pane the data will be displayed as a table.
• Ensuring the pink input item is selected, click the Decode button in the Left pane to add a Decode transform. If the button isn’t showing, check show advanced in the Left pane.

• In the Right pane check the column(s) you wish to decode and set Change to From base64 encoding. This will change the selected columns from base64 encoding to plain text.

• You can now output the data to a new file in a range of formats. Scroll to the bottom of the Left pane and click To File. A window will appear. Set the new file name, location and file type.

• A green output item is added and selected.

• The new file with the decoded base64 data is created immediately at the chosen location. No need to ‘run’ anything.

If you have a large number of files to convert you can do it using the batch processing feature.

As well as decoding base64, Easy Data Transform also allows you to combine 66 transforms such as stack, join, dedupe and filter to quickly and easily get your data in the exact form you need it.
