I am developing a source in SSIS VS 2017 which calls REST API using script Component and serialises JSON and provides records which I am storing in SQL Table. While designing I need add output columns which are 200+ manually and set properties like data type and length manually for each and every column which is very tedious. Can any please suggest how can I add all those columns using a program and set properties using code or may be I just create one excel and just import it and it’s done in one second. Please help brainstorm and suggest ideas VSTA is one option but I don’t know how to do it? Where to start from!! Thank you, Kunal

I totally agree with @Arthur comment, you should build the whole package programmatically. You have two approaches to create packages programatically:

(1) Build SSIS using C#

If you are familiar with C# you have two choices:

(a) Using SQL Server Client SDK assemblies

This is the official traditional way to create ssis packages programmatically, there are many link on the internet that you can refer to such as:

Creating a Package Programmatically
Samples for creating SSIS packages programmatically

(b) Using EzApi – Alternative package creation API

EzAPI is a .NET library written in C# by Evgeny Koblov one of the testers on the SSIS team to abstracts away a lot of the cumbersome low-level coding needed to create SSIS packages XML directly in a programming language

GitHub - EzApi2016
NuGet Gallery - EzApi

There are many link on the internet that you can refer to such as:

(2) Build SSIS using BIML

If you are familiar with XML, then you should use BIML (Business Intelligence Markup Language) which is a markup language developed by Varigence and can be integrated within Visual Studio to create packages without the need of coding experience.

There are many links that you can refer to learn BIML:

Update 1 - C# approach

Recently i started a new project on Git-Hub, which is a class library developed using C#. You can use it to import tabular data from excel, word , powerpoint, text, csv, html, json and xml into SQL server table with a different schema definition using schema mapping approach. check it out at:
