mt-940
A library to parse MT940 files and returns smart Python collections for statistics and manipulation.
Decision gist · record as of 2026-08-14
Yes. Actively maintained, zero runtime dependencies, ships with full type information, and handles a wide range of real-world bank formats. Suitable for any Python project that needs to parse MT940 statements reliably. No known security issues, permissive license, and low install friction make it a straightforward choice.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or newer.
- Low friction: pure Python with zero runtime dependencies, ships as a wheel, and actively maintained with a recent release 53 days ago.

What it is and what it does
This is a parser for MT940 bank statement files—a SWIFT standard format used by banks worldwide to exchange transaction data. It reads these files and returns fully typed Python collections where transactions, amounts, balances, and dates are rich objects rather than raw strings, making them immediately usable for aggregation, filtering, and analysis.
The library has no runtime dependencies and includes type information (py.typed), so it works cleanly in typed codebases. It handles quirks from many real banks through a combination of sensible defaults and opt-in extensions: you can parse a standard statement with a single call, but for banks with non-standard tag layouts, you can register custom tag handlers. It also supports multiple statements in one file, JSON serialization, and custom transaction grouping rules.
Use it for
- Extract and reconcile bank transactions from MT940 files into a Python application for accounting or bookkeeping.
- Aggregate statement-level data like opening and closing balances across multiple bank files for financial reporting.
- Serialize parsed statements to JSON for downstream processing, APIs, or storage in a data pipeline.
- Handle bank-specific MT940 variants by registering opt-in tags without forking the parser.
- Build transaction analysis tools that work with typed amount and date objects instead of parsing strings manually.
