TXT to MT940 Converter: Create MT940 Statements From Text Online Free
Free TXT to MT940 converter to generate bank-format MT940 statements from plain text data, in your browser. Private, no uploads, no sign-up.
Plain Text In, Bank-Standard Out
When a system delivers transaction data as simple text, converting it to MT940 makes it digestible for banks and treasury tools. Generating MT940 from plain text standardizes raw rows into the tagged format importers expect.
No spreadsheets, no manual re-keying — structured output directly.
ChooseTools converts TXT to MT940 locally in your browser.
How to Convert Text to MT940
From free text to a compliant statement:
Paste your plain-text transaction lines, describe the layout (date, amount, description order), and generate the MT940 file ready to deliver to your recipient.
Conversion runs locally, preserving confidentiality.
Line Layouts Read Automatically
Simple, predictable text rows convert into structured MT940 tags.
Dates and amounts normalize to the format's expectations.
The converter hands import-ready statements instead of raw notes.
For Testing Statements and Legacy Systems
Mock statement files for integration tests come quickly from plain text fixtures.
Legacy exports migrate into usable bank formats without spreadsheets.
Data flows into modern pipelines instead of sitting in a text file.
Standard Structure, Zero Manual Edits
Field positions and line lengths form automatically.
Consistency guarantees that downstream parsers validate the file cleanly.
Bank-grade results from the first attempt.
Private Statement Building
Plain text data may hold account numbers and balances; local conversion seals them.
No upload, no account, no watermark — across platforms.
Private pipelines, compliant output.

The toolkit is free and browser-native.
Text lines become banking-fluent files.
MT940 Tag Structure and What Each Field Means
The MT940 format organizes data into a sequence of tagged fields, beginning with a basic header statement tag that identifies the account and statement period.
Transaction lines use a dedicated tag that encodes the value date, booking date, debit or credit indicator, amount and reference in fixed positions.
An informational tag carries free-text details such as the transaction description, counterparty name and any remittance information the bank includes.
Understanding these tags helps you verify that the converted output matches what your treasury management system or accounting software expects to receive.
Date Formats and Currency Normalization
Banks commonly express dates in the six-digit format used across SWIFT messaging, while plain text sources may provide dates in various regional arrangements.
The converter normalizes date strings to the bank-standard format regardless of whether your source uses dashes, slashes or compact numeric sequences.
Currency amounts are parsed from the text and placed into the correct positional fields, handling decimal separators and thousands grouping as needed.
This normalization step eliminates the most common reason MT940 imports fail: malformed dates or amounts that do not conform to the expected layout.
Generating Test Fixtures for Integration Pipelines
Development teams building treasury integrations need realistic MT940 fixtures to test parsers, reconciliation engines and dashboard imports.
Creating those fixtures from plain text data is significantly faster than exporting them from a live bank environment, especially during early development stages.
The converter lets you iterate quickly: adjust a transaction row in the text, reconvert and feed the result into your test suite within seconds.
This rapid feedback loop catches parsing bugs before they reach production, where misclassified transactions can cause reconciliation headaches.
Common Validation Errors and How to Avoid Them
Banks reject MT940 files that have missing mandatory tags, incorrect line lengths or amounts that do not balance within a statement section.
The converter enforces field lengths and character positions automatically, preventing the majority of structural validation failures before you download the file.
If your source text is missing a required field such as the account number or statement number, the tool flags the issue during conversion rather than producing an incomplete file.
Running a validation check after conversion gives you a final confirmation that the output will pass the importer's format gate on the first submission.
Handling Multiple Accounts in One Conversion
Organizations managing several accounts often need to produce separate MT940 statements for each, even when the source text contains intermixed transactions.
The converter lets you group transactions by account identifier before generating the output, ensuring each statement file corresponds to exactly one account.
This grouping prevents the downstream reconciliation errors that occur when a single file contains mixed account data that parsers cannot separate cleanly.
Batch-friendly design means you can process multiple text excerpts sequentially without reconfiguring the layout mapping each time.
Frequently asked questions
What does the converter need from my text file?
Predictable rows containing at least a date, an amount and a description; the layout is confirmed during conversion.
Why would I generate MT940 from text?
To feed legacy exports, test fixtures or plain export rows into banking systems that accept MT940.
Is the conversion private?
Yes. Everything runs locally in your browser with no uploads or accounts.
What date format does the output use?
Dates are normalized to the six-digit SWIFT format that MT940 parsers expect, regardless of the format in your source text.
Can I produce separate statements for multiple accounts?
Yes. The converter lets you group transactions by account identifier so each output file corresponds to a single account, preventing downstream reconciliation errors.
