Is it possible to store a string in a database field and then parse it?

Question

Django

Is it correct to store a string of this kind in a database field? And then parse it? Or do I need to create a connection, if so, what kind? ManyToMany or another?

class Fams(models.Model):
    word_fams = models.TextField(blank=True, null=True)

class Word(models.Model):
    word_en = models.TextField(unique=True)
    example = models.ManyToManyField(Example, blank=True)
    fams = models.ManyToManyField(Fams,blank=True)

word_fams is the field where you want to store the string
