-====== Introduction (File Reader v2) ====== 
  
-This page describes the use of the “File Reader” tool in Bizweaver. Information regarding the associated File Operations and File Writer tools is found in separate documents. 
  
-===== Special Note ===== +====== File Reader Tool ====== 
- +The **File Reader** tool is used to read data from “flat” delimited files and “structured” formats such as XML, JSON, Microsoft Excel. Plain text can also be read with “text reader” as a single string.
-<WRAP center round important> +
-Beginning in Bizweaver v2.0.170, two File Reader tools are displayed: FileReader and FileReader2. The functions are the same in both tools except for handling XML and JSON files found in FileReader2. While workflows created using FileReader will continue to function, any new workflows should use FileReader2. All references to “FileReader” in this section refer to FileReader2. +

-====== FileReader Tool ====== +
-The **File Reader** tool is used to read data from “flat” delimited files and “structured” formats such as XML, JSON, and Microsoft Excel. There is also a special input type called “text reader.” Data read from the file is then available in subsequent processing steps.+
  
 The File Reader tool is also used to process data being received from a webservice call. More information on this process can be found in the **//[[bw2:web_service_tool|Webservice Tool]]//** page. The File Reader tool is also used to process data being received from a webservice call.

   - The File Reader requires the use of a “template” file. This is simply an abbreviated version of the file to be processed (the template file can be the same file that is being processed but it's easier to debug a problem with a static file when and if the file structure changes). The template is used to define the expected columns when reading an input file.   - The File Reader requires the use of a “template” file.

-If the input structure is complex, you may need to use multiple FileReader steps (with a common input) to get all the data elements you need.
