Overview
NACHA ACH file viewer. Parses files locally in your PC-browser — no network, nothing transmitted/received
NavAch is an ACH File Editor that inspects and validates the files (NACHA-formatted ACH files), and allows the user to view the content in a human readable form. Its advanced/premium features allow the user to search, edit, and create ACH formatted files. Everything runs locally. NavAch parses it entirely inside your browser – no upload, no server, no network request of any kind. For financial institutions and their partners, that means the file never leaves your machine, meeting security and privacy requirements with no extra configuration. An additional privacy feature is “Redaction Mode”: This masks account information and routing numbers so a file can be reviewed or screen-shared without exposing sensitive banking details. NavAch allows users to quickly open, navigate, and inspect NACHA-formatted ACH files in a clear, human-readable format. It helps users understand file contents, verify ACH structure and control totals, operational verification, fraud and compliance checks, and troubleshoot potential errors before processing payments or after the fact for auditing, support, and compliance purposes. All securely within the browser without transmitting sensitive data. Users include Banks and Credit Unions, FinTechs and BaaS companies, Tech teams, Compliance and Audit Teams, Customer Support, and ACH professionals learning NACHA. Other features include: search, export, format conversion. We're actively building out more features related to Metrics and Controls that include compliance tooling.
