Extract text from financial data files (NCH)
To convert NCH data files to another format, you need QuickBooks or other Data software.
To convert other file formats to the "Financial Data File" file type, you need software like QuickBooks or a similar tool.
The .nch file is primarily an ACH transaction data file built on the strict NACHA standard. It is commonly used as a digital bank statement or a batch of transfer instructions imported into accounting systems like QuickBooks. It contains structured payment data required for automated clearing house transfers between banks. A secondary, mostly obsolete use for this extension is the Outlook Express Folder File by Microsoft.
Users face major limitations when handling .nch files outside of dedicated banking environments. The NACHA format relies on an archaic 94-character fixed-width string layout. It has no delimiters like commas or tabs. If you try to open it in a basic text editor or a browser, it looks like an unbroken wall of numbers and codes. It is completely unreadable for the average user. Standard spreadsheet tools like Microsoft Excel cannot parse these files without manual, tedious column mapping, which often leads to expensive accounting errors.
The best workaround is converting the .nch file to CSV, XLSX, or PDF. Converting to CSV translates the rigid fixed-width strings into clean, separated columns that any spreadsheet application can immediately read, making financial auditing and reporting much easier.
Because this format is highly specific and relies on closed financial network protocols, standard online converters usually fail to process it correctly. Just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can securely inspect the raw text inside your .nch file. If our analysis detects standard NACHA formatting, we can help extract the underlying transaction data into a more usable spreadsheet format.
Convert.Guru analyzes your NCH file, detects the exact format, and lets you read the text inside.
Users also converted NLCH, EPUB, ZIP, SKF, BU and SEC files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NCH converter.
