Zengin to CSV Reconciler
Transform opaque, fixed-width Zengin (.txt) bank files into readable CSV format for Excel auditing and reconciliation.
No data parsed yet. Paste a Zengin file to begin.
Supports standard Japanese Banking Association (Zengin) fixed-width file format.
Common Problems
Can I use this for non-standard bank file formats that aren't Zengin?
This tool is specifically engineered to interpret the strict structural rules defined by the Zengin standard and will likely produce erroneous results with other formats. Other proprietary bank file layouts require custom mapping logic that this utility does not currently support.
Why does my file report a validation error even if the data looks correct?
Validation failures typically occur when the trailer record's calculated hash total or expected transaction count does not match the actual data provided in the file. Double-check that your source text is complete and hasn't been truncated or improperly pasted into the input field.
Can this tool handle encrypted or password-protected Zengin files?
The tool is designed to work with plaintext files and does not contain functionality to decrypt or bypass security layers. You must ensure the file is in an unencrypted state before attempting to process it through the interface.
Why are some Japanese characters appearing as garbled text in the output?
This issue usually stems from character encoding mismatches, specifically if the input file uses Shift-JIS instead of UTF-8. Ensure your source file's encoding is compatible with the environment, or convert the raw text to a standard format before pasting.
Is it possible to export the results directly to an Excel binary file?
The tool outputs clean, comma-separated values (CSV) which are natively compatible with Excel without needing a binary file export. You can open the generated CSV directly in your spreadsheet software and save it as an .xlsx file if you require native Excel features.
Workflow
What is Zengin to CSV Reconciler?
The Zengin to CSV Reconciler is a specialized utility designed to decrypt the dense, fixed-width format of Japanese Zengin bank transfer files into human-readable CSV documents. By automating the extraction of header, data, and trailer records, it eliminates the tedious manual effort typically required to prepare bank data for accounting software or spreadsheet reconciliation.
How to use Zengin to CSV Reconciler
Paste the full content of your raw Zengin (.txt) file directly into the input area, ensuring the fixed-width structure is preserved. Click the Parse & Reconcile button to trigger the internal validation engine, which automatically verifies total counts and transaction amounts against the file's trailer records. Once verified, download the resulting CSV file or copy the processed tabular data directly to your clipboard for immediate use in Excel or Google Sheets.

1. Validating end-of-month bank transfers against internal ledger records to ensure balance accuracy.
2. Converting bulk transfer history files into formatted spreadsheet lists for stakeholder reporting.
3. Troubleshooting mismatched batch counts or invalid total amounts in automated payroll submissions.
4. Preparing legacy bank data for migration into modern cloud-based ERP or accounting systems.
FAQ
What file formats are supported for input?
The tool specifically handles standard Zengin (.txt) fixed-width format files, which are common in Japanese inter-bank clearing systems. Ensure your file adheres to the typical 120-character record length to guarantee accurate parsing.
How does the tool perform reconciliation?
The reconciler automatically calculates the hash total and transaction counts based on the processed data lines and compares them against the embedded values in the file's trailer record. If there is any discrepancy in record counts or monetary amounts, an alert is triggered to notify you.
Is my sensitive financial data uploaded to a server?
No, all parsing, validation, and reconciliation logic are executed entirely within your browser environment. Your bank data never leaves your computer, ensuring complete privacy during the conversion process.
