Script to import json file to SQL - Need Fast

Hello. I have the attached json data file that I need imported to SQL. There are many nested arrays in this file. I believe the basic schema is:
documents [
"land_type",
"document_number",
"recorded_date",
"document_type",
"grantors",
"grantees",
"legals",
"related_documents",
"found_on_certificates"]

Grantors, Grantees, legals, related_documents, Found_on_certificates all have multiple nested arrays.

I've tested my file on a few "convert json to SQL sites", but it creates a single table with about 250 columns expanding infinitely depending on how many arrays there are. For example, it will end up columns for legals0, legals1, legals2, etc.

What I'm HOPING to end up with is an SQL Database with relational tables for the nested arrays). Something like:

Documents(ID, "land_type", "document_number","recorded_date","document_type")
Grantors(ID, "first_name", "mid_name","last_name", "long_name")
Grantees(ID, "first_name","mid_name","last_name", "long_name")
Legals(ID, "plat_name","block", "lots")
Related_Documents(ID, "land_type", "document_number", "document_type")
Certificates(ID, "certificate_numbers")

** Please note. I have just been browsing the json file to find applicable fields. Hopefully I have accounted for everything in this example.

I will have several of these files to import so I'm looking for a T-SQL solution to import/parse this data as described above.

This is a last minute project for us and we have a meeting in 8 hours to provide proof we can accomplish this.

Willing to pay considerable bonus if you can produce this in a short (few hours) period of time.
