Browser-based utilities for SEPA payment XML files (pain.001.001.03).

Tools

Date Modifier

Update execution dates in SEPA payment files.

Payment QR Codes

Generate one EPC payment QR code for each transfer in a SEPA XML file.

Problem

Banks reject SEPA payment files with past execution dates. When you have an XML payment file with an outdated ReqdExctnDt (Requested Execution Date), you need to update it before uploading to your bank.

Solution

This tool runs entirely in your browser - no server, no data upload, complete privacy. Just open the HTML file and modify your payment dates.

Features

• Drag & drop or click to upload XML file
• Date picker defaults to today's date
• Preview shows: original date, new date, transaction count, total amount
• Download modified XML with updated dates
• Generate one QR code per CdtTrfTxInf payment
• Print the QR sheet or download each code as PNG
• Updates both ReqdExctnDt and CreDtTm timestamps

Usage

1. Open index.html in any modern browser
2. Drag & drop your SEPA XML file (or click to select)
3. Use the Date Modifier tab to change execution dates and download the updated XML
4. Use the Payment QR Codes tab to render one EPC QR code for each payment
5. Print the QR sheet or download individual QR codes as PNG
