So, I have a spreadsheet with about 5000 rows. Each of these rows has a unique number in column A, followed by some data in column B:

```
| A | B |
|-------|------------|
| 5142 | Test |
| 5348 | Some stuff |
| 32665 | More stuff |
| 74568 | More stuff |
```

In another spreadsheet, I have some different data, for SOME of the IDs in my first spreadsheet, but not all of them:

```
| A | B |
|-------|-----------|
| 5348 | 1/1/2017 |
| 74568 | 6/25/2018 |
```

What I want to do is copy these columns from the second spreadsheet into the first spreadsheet, but I need the rows to spread out to paste into the corresponding rows from spreadsheet 1, so what I end up with is this:

```
| A | B | C | D |
|-------|------------|-------|-----------|
| 5142 | Test | | |
| 5348 | Some stuff | 5348 | 1/1/2017 |
| 32665 | More stuff | | |
| 74568 | More stuff | 74568 | 6/25/2018 |
```

Any idea how I can accomplish this?
