Under most circumstances you can use the combine command to flatten and the split command to unflatten.

You will need two delimiters that are not in the keys and elements. I imagine even weird control characters will work for these. If you store binary data, such as images, then you don't meet these requirements. (Unless the binary data is made text.) See below if you need binary keys or elements.
Keys are strings. Elements may be internal numbers as well as arbitrary strings. These are converted to strings using the information in the numberFormat property. That means that unless you are careful, you might end up with big strings for large numbers or information lost for small numbers. If you don't store numbers, don't worry about it.
If you need to save arbitrary arrays that may have any character (byte) in them, you need to go to a fancier method. I am working on one as part of my nodes-or-boxes-or-whatever project. I can make that available early if this is important to you. I have not tested my method yet, but I expect it to work. It will be slower than combine, but it should be suitable for data to be stored in a file.
So... Look in the TD for "combine", "split" and "numberFormat".
