CSV invoice batches: check the preview before downloading XML

ARLing s. r. o. · 12 September 2026

The ARLing batch generator turns CSV item rows into UBL XML. A batch can contain up to 100 invoices and 500 item rows in total. Preview and supported checks are free before purchase, so you can inspect the result before deciding whether to download the files.

Keep the invoice number consistent

Use the CSV column invoice_number to group items. Rows with the same value belong to the same invoice. Several item rows therefore do not necessarily mean several invoices; the limits apply to both invoice count and the total number of item rows.

Review before downloading

Run the batch check and inspect the invoice previews before continuing. Use the supported checks to review the input and resulting XML, rather than treating a generated file as proof that every requirement has been met. Downloading the prepared XML files together as a ZIP requires valid 30-day access.

Where the CSV is processed

The CSV content and generated XML are processed in your browser and are not sent to a server. This statement concerns the document content, not payment processing.

Try the batch preview

Open the CSV invoice batch page to inspect the supported input format, then use the e-invoice tool to preview and check a batch before downloading it.
