sort dates inside a cell

Hello. Is it possible to chronologically sort a number of dates inside a cell, that are not dates but strings?

20170629

20190507

20010406

20040706

20031209

20061226

20031209

20060815

20050426

20061221

20090407

20080904

20100331

20170704

I want to have the oldest date on the top. Alternatively, is there a way to extract the oldest date?

Thank you.
