How to import JSON file into SQL Server table

There are several ways to import a JSON file into a SQL Server table, including using built-in functions, using third-party tools, or writing a custom script.

Here is an example of how to import a JSON file into a SQL Server table using the built-in OPENJSON function:

Create a table: Create a table in SQL Server with the same structure as the JSON file.

CREATE TABLE mytable (
    id INT,
    name VARCHAR(50),
    age INT
)

Import the JSON file: Use the OPENJSON function to import the JSON file into the table.

INSERT INTO mytable
SELECT *
FROM OPENROWSET (BULK 'C:\myfile.json', SINGLE_CLOB)
WITH (
    id INT '$.id',
    name VARCHAR(50) '$.name',
    age INT '$.age'
)

The OPENJSON function parses the JSON file and maps the values to the columns in the table. The WITH clause specifies the mapping of the JSON properties to the table columns.

It’s worth noting that the OPENROWSET function requires the BULK option and the SINGLE_CLOB option to be enabled. Also, it may need to enable ad-hoc distributed queries by using the following statement:

Exec sp_configure 'show advanced options', 1; 
GO 
RECONFIGURE; 
GO 

Exec sp_configure 'Ad Hoc Distributed Queries', 1; 
GO 
RECONFIGURE; 
GO

It’s important to test the import process in a test environment before moving it to production and to validate the data to make sure that it’s loaded correctly.
