Perhaps it should be: JSON doesn't allow for elegant formatting of multi-line strings, so all multi-line input and output is...

That seems like a good wording. I copied the text from the existing JSON data from food-chain by the way.

I think I missed a small thing - no spaces after the comma, right?

(I also haven't checked with code, so I may have missed others, but I least see this)

I'll send the PR. This was the only thing.

Rows become columns and columns become rows. See <https://en.wikipedia.org/wiki/Transpose>.

If the input has rows of different lengths, this is to be solved as follows:

- Pad to the left with spaces.
- Don't pad to the right.

Therefore, transposing this matrix:

```
ABC
DE
```

results in:

```
AD
BE
C
```

And transposing:

```
AB
DEF
```

results in:

```
AD
BE
F
```

In general, all characters from the input should also be present in the transposed output.
That means that if a column in the input text contains only spaces on its bottom-most row(s),
the corresponding output row should contain the spaces in its right-most column(s).
