¶ Data transfer - import and export in Hummerce

Data transfer in Hummerce is a set of panel tools that let store staff exchange data with Excel and XML files on their own - items, stock levels, prices, customers and other catalog objects - without a developer's help for every update. Each type of data has its own transfer, but they all follow the same rules: a test mode before saving, background processing, and a clear summary at the end.

Last updated: 2026-09-29. The transfer mechanism is a core platform feature - available in all current store versions.

¶ Transfers list in the panel

The Data transfer menu shows all transfers configured in the store. After choosing a transfer, you still need to pick a direction - import or export (some transfers only support one of them). Standard platform transfers:

Items (xls) - full catalog import and export from Excel: prices, categories, visibility, properties - see Item import and export (xls).
Items (xml) - an alternative catalog exchange format, used e.g. for file-based integrations - see Item import (xml).
Bulk operation on items - changing one field (e.g. the main category) for many items at once, selected by criteria - see Bulk operations on items.
Stock import - updating item quantities in warehouses from an Excel file - see Stock import from an Excel file.
Customer export and order export - a data extract to a CSV file - see Customer and order export.
Import of extensions, property types and the location tree (xml) - configuration of properties and their layout in forms, usually during implementation.
Item photo import - uploading photos from a file server and assigning them to items by symbol.
Payments (xml) and messages (xls) - configuration of payment methods and store texts from a file, usually during implementation.
Waybill numbers (xls) - bulk assignment of a shipment number to orders.

Which transfers are visible in the menu depends on the specific store's configuration - not all are enabled right away.

¶ Common rules for transfers

Test mode - the transfer checks the whole file, but rolls back the transaction at the end, so nothing is saved in the store. Lets you catch file errors before the actual import.
Append mode - depending on the transfer, decides whether objects outside the file are left unchanged, or get a deleted status (so the file's content fully matches the store's content).
Ignore errors - by default, the first invalid row (a wrong symbol, wrong price, wrong boolean value) stops the whole transfer. With this option, the invalid row is skipped and the transfer continues - lets you catch all file errors in a single run.
Timestamp the file - on by default; appends the date and time to the file name, so you can keep successive versions of the same file.
Background processing - the transfer runs server-side, independently of the panel: progress and messages (each with a timestamp) are shown live, and the transfer can be stopped at any time with the STOP button, which rolls back the transaction.
Results and reports - when the transfer finishes, an alert shows a summary; with ignore errors on, the summary lists the skipped rows and the reason. Export also lets you download the resulting file right away.

¶ Bulk operations on items

A separate Bulk operation on items transfer changes one selected field (e.g. the main category, or removal from a category view) for many items selected by criteria (e.g. category, producer, property) - instead of opening and saving each item individually on its item card. Unlike file imports, it has no test mode - the change applies immediately to the selected items. Details: Bulk operations on items.

¶ Frequently asked questions

Can the file be checked before saving changes in the store?
Yes. Test mode checks the whole file and rolls back the transaction at the end, without saving anything in the store.

Does an error in one row stop the whole import?
By default, yes. With ignore errors turned on, the transfer skips the invalid row, shows it in the summary, and continues with the rest of the file.

Do you need to watch the transfer until it finishes in an open panel?
No, you don't need to wait at the computer - the transfer runs server-side, and the panel just shows its current state; the result and any errors are visible in the summary when you come back to the panel.

Can only selected items be imported, without touching the rest?
It depends on the transfer - in append mode (e.g. for stock import), only the items from the file are updated, the rest stays unchanged.

Does a transfer adapted to a customer's non-standard file require implementation?
Yes, when the file has a different column layout than the platform standard - adapting the transfer is quoted individually after analyzing the file.

Stock import from an Excel file
Warehouse - the warehouses stock is imported into.
AI assistant - MCP server - selected transfers (properties, extensions) are also available as AI assistant tools.
