SSIS JSON Connector

JSON Connector can be used to extract and output JSON data coming from REST API web service calls (Web URL) or direct JSON String (variables or DB columns) or local JSON files data. JSON Connector also supports JSONPath to filter data from nested array/sub-documents. This Connector is optimized to work with very large JSON string.
You can use this connector to integrate REST API data inside SSIS and SQL Server. Let's take a look at the steps below to see how exactly to accomplish that.

Video Tutorial - Integrate JSON data in SSIS

This video covers following and more so watch carefully. After watching this video follow the steps described in this article.

  • How to download / install required driver for JSON integration in SSIS
  • How to configure connection for JSON
  • Features about JSON Source (Authentication / Query Language / Examples / Driver UI)
  • Using JSON Connection in SSIS


Before we perform steps listed in this article, you will need to make sure following prerequisites are met:
  1. SSIS designer installed. Sometimes it is referred as BIDS or SSDT (download it from Microsoft site).
  2. Basic knowledge of SSIS package development using Microsoft SQL Server Integration Services.
  3. Make sure ZappySys SSIS PowerPack is downloaded and installed (download it). Check Getting started section for more information.
  4. Optional (If you want to Deploy and Schedule ) - Deploy and Schedule SSIS Packages

How to read data from JSON in SSIS using JSON Source (Export data)

In this section we will learn how to configure and use JSON Connector in the API Source to extract data from the JSON using JSON Source.

  1. Begin with opening Visual Studio and Create a New Project.

  2. Select Integration Service Project and in new project window set the appropriate name and location for project. And click OK.

  3. In the the new SSIS project screen you will find the following:

    1. SSIS ToolBox on left side bar
    2. Solution Explorer and Property Window on right bar
    3. Control flow, data flow, event Handlers, Package Explorer in tab windows
    4. Connection Manager Window in the bottom
    SSIS Project Screen
    Note: If you don't see ZappySys SSIS PowerPack Task or Components in SSIS Toolbox, please refer to this help link.

  4. Now, Drag and Drop SSIS Data Flow Task from SSIS Toolbox. Double click on the Data Flow Task to see Data Flow designer.
    SSIS Data Flow Task - Drag and Drop

  5. From the SSIS toolbox drag and drop JSON Source on the dataflow designer surface
    SSIS JSON Source - Drag and Drop

  6. Double click on JSON Source component to configure it.

  7. From the Access Mode dropdown select [File path or web Url] and paste the following Url for this example.
    NOTE: Here for demo, We are using odata API, but you need to refer your own API documentation and based on that you need to use your own API URL and need to configure connection based on API Authentication type.

  8. Now enter JSONPath expression in JSONPath textbox to extract only specific part of JSON string as below ($.value[*] will get content of value attribute from JSON document. Value attribute is array of JSON documents so we have to use [*] to indicate we want all records of that array)
    NOTE: Here, We are using our desired filter, but you need to select your desired filter based on your requirement.
    Click on Preview button to view the parsed JSON string response data and click OK.

  9. That's it; we are done. In a few clicks we configured the call to JSON using ZappySys JSON Connector

Read large JSON string in SSIS (3 Million Rows in 3 Mins)

Using ZappySys SSIS JSON Source you can read large JSON String data (Process 3 Million rows in 3 minutes – 1.2 GB file). Using --FAST Expression and other options.

If you use default settings to read data then it may result into OutOfMemory Exception so we will outline few techniques which will enable high performance Streaming Mode rather than In-memory load of entire data.

Load JSON data in SQL Server using Upsert Destination (Insert or Update)

Once you read data from the desired source, now let's see how to Load JSON data in SQL Server using Upsert Destination. Upsert Destination can Merge/Synchronize data from source to target for Microsoft SQL Server, PostgreSql and Redshift. It supports very fast Bulk Upsert (Update or Insert) operation along and Bulk delete.

  1. From the SSIS toolbox drag and drop Upsert Destination on the dataflow designer surface

  2. Connect our Source component to Upsert Destination

  3. Double click on Upsert Destination component to configure it.

  4. Select the desired Microsoft SQL Server/PostgreSql/Redshift Target Connection or click NEW to create new connection. Select Target Table or click NEW to create new table based on source columns.
    Configure SSIS Upsert Destination Connection - Loading data (REST / SOAP / JSON / XML /CSV) into SQL Server or other target using SSIS
    Configure SSIS Upsert Destination Connection - Loading data (REST / SOAP / JSON / XML /CSV) into SQL Server or other target using SSIS

  5. Set Action to Upsert => (insert if not matching in target else update). Select Target Connection and Target Table. Check on Insert and Update. Click on Map All to Mappings all columns and check on Only Primary Key columns.
    SSIS SQL Upsert option

  6. Click on OK to save Upsert Destination settings UI.

  7. That's it; we are done. Run the SSIS Package and it will read the data from the JSON and load the the data in the SQL Server/PostgreSql/Redshift.
