SSIS comes with out-of-the-box support for reading and writing to Excel. However, it’s very restrictive if you want to make things dynamic, as any metadata inside DataFlow cannot be changed at runtime. Here are a few problems with using the native Excel Source or Destination.

• Metadata cannot be changed at runtime.
• Datatype guessing nightmare – only the first few rows are scanned, and the wrong datatype is selected.
• Cannot export multiple tables to Excel.
• Cannot split data into multiple tabs based on specific grouping criteria
• Cannot specify the location where data has to be written

SSIS export to Excel dynamically using Excel Export Task

If you want to generate Excel dynamically without any of the above hassle, then you can check the SSIS Excel Export Task. It comes with many advantages not found in the native Microsoft SSIS Excel Destination

Here is the list of a few features for the SSIS Excel Export Task

• Export multiple tables/views to Excel files (e.g., Sales% or do SalesJan|SalesFeb).
• Support for all major office versions (e.g, Office 2003, 2007, 2013+).
• Export SQL query output to an Excel file.
• A completely dynamic approach without limitations on DataFlow Strict Metadata.
• Option to export data to a specific starting location in an Excel Sheet (e.g, A5 will start writing to the  5th row, 1st column).
• Support for a password-protected Excel file.
• Option to clear a range of cells before writing data to an existing Excel workbook (e.g., A1:D5000 will clear A to D columns from 1st to 5000 rows).
• Automatically Split exported Excel data into multiple files by Size or Number of records.
• Automatically Split exported Excel data into multiple files or tabs when Split By Column (e.g., SplitBy=Country will create a new file for each country). If the SplitOnTab option is specified, then data is written to a new Excel tab rather than a file for each new group.
• Support for Compression and Append.
• Fully managed means it works out of the box on both 32-bit and 64-bit systems without any changes (Note that Native SSIS Excel functionality is 32-bit only).
• Support for SQL Server 2005, 2008, 2012, 2014 (32-bit and 64-bit).

SSIS PowerPack supports various methods for making things dynamic. Sometimes you have to consume JSON Data from a Dynamic URL. There are 3 different ways you can make JSON Source URL Dynamic.

• Use Expression on the DirectPath property of the JSON Source (SSIS Data Flow Expression)
• Use variable placeholders directly inside URL (Only works when you use DirectPath mode)
• Use PathFromvariable AccessMode and define an expression on an SSIS variable

Use SSIS Data Flow Expression

So you change any property of the SSIS Data Flow component at runtime using an expression:

Use Variable Placeholders

SSIS PowerPack supports Variable Placeholders for easy editing and making values dynamic. Variable placeholders are directly visible, unlike expressions, which are hidden. See the screenshot below for an example of how to type a variable placeholder, which gets replaced by the actual value of the SSIS variable at runtime.

SSIS dataflow Expression alternative – Using Variable Placeholders

PathFromVariable mode and Use Expression on Variable

If you choose a path from a variable, then you can define an Expression on the variable to make your path dynamic at runtime.
