The name Heidi in Hebrew letters is הידי. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
הידי
In short
Your name in Hebrew letters is הידי. A German pet form of Adelheid, “of noble kind”. The Swiss novel “Heidi” by Johanna Spyri (1880) carried it around the world. In Hebrew it is written by sound. Adding up the numbers of its letters gives 29 — the same as the Torah word דכה, “crushed”. That number points to Torah page 29 of 354 — in the portion Vayera. What that portion is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah. The verse that begins with the first letter of your name and ends with the last is Genesis 4:14. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Heidi” — this exact spelling is what was calculated: הידי. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name הידי gives 29.
29
The number 29 is the Torah word דכה — «crushed» (Deuteronomy 23:2).
And it came to pass on the morrow, that the first-born said unto the younger: 'Behold, I lay yesternight with my father. Let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father.'
This is from the portion Vayera. What it is about: Three visitors at Abraham's tent; the plea for Sodom; the birth of Isaac; the binding of Isaac on Mount Moriah.

הן גרשת אתי היום מעל פני האדמה ומפניך אסתר והייתי נע ונד בארץ והיה כל מצאי יהרגני
