title: What is the Miller command for separating emails into their own rows, while also copying down other column data?
body: <p>I have a very large csv file (213,265 rows) with many columns.</p>
  <p>In one of those columns I have some emails seperated by commas. A trimmed down version of the csv file looks like this:</p>

  <p>I would like to use <a href="https://github.com/johnkerl/miller" rel="nofollow noreferrer">Miller</a> to seperate out those emails into their own rows, but also copy down ALL the other columns in the spreadsheet (many of which aren't shown here in this simple example).</p>
  <p>Following on with this example, I would like to end with something like this. But keep in mind the real spreadsheet has many other columns before and after the email column:</p>

  <p>Is that possible to do with Miller (or another similar tool)? What would the command look like?</p>
