## What You Want to Do

I want to encode the string data in a column as Base64.

## Solution

For example, to encode string data in a “name” column as Base64 in Exploratory, follow these steps:

1. Add a **Create Calculation** step.
2. Enter the following code in the Calculation Editor:

```r
sapply(name, function(x) base64enc::base64encode(charToRaw(x)))

```

3. **Run** the calculation and check the encoded results.

By following these steps, you can successfully encode the string data in a specified column as Base64.
