ACH Nacha file report script in PowerShell

I created the Nacha-Report.ps1PowerShell script to simplify the analysis of NACHA files in a more human readable format.

In the realm of banking and fintech, understanding the flow of electronic transactions is crucial, and the Nacha-Report.ps1 script provides an efficient solution to analyze these transactions securely and comprehensively.

What is NACHA?

NACHA (National Automated Clearing House Association) manages the ACH Network, facilitating the electronic transfer of funds between banks and credit unions in the United States. NACHA files are structured in a fixed-width ASCII format, where each line, or record, represents different aspects of financial transactions.

Why Nacha-Report.ps1?

This script parses a ACH/NACHA file to generate a summary report, avoiding sensitive account information to ensure data privacy and security. It's crafted to aid financial analysts, auditors, and fintech professionals in scrutinizing ACH transactions without compromising on confidentiality.

Key Features:

  • Comprehensive Analysis: Generates detailed reports from NACHA formatted files.
  • Privacy-Focused: Excludes sensitive account details from the output.
  • User-Friendly: Offers test data download for immediate functionality check.
  • Customizable Output: Includes a switch to display detailed trace information for transactions.


PS> Install-Script -Name nacha-report

How to Use:

Running Nacha-Report.ps1 is straightforward. You simply need to provide the path to your NACHA file:

PS> .\Nacha-Report.ps1 -nachaFilePath "C:\Path\To\Your\File.txt"

Don’t have a NACHA file on hand? Test the script's functionality with sample data:

PS> .\Nacha-Report.ps1 -testdata

Report Insights:

The script meticulously crafts a report highlighting key transaction details, such as file creation dates, batch numbers, transaction codes, and amounts, all formatted for easy understanding and analysis.
