From a Google Sheet to a production-ready XML feed
A platform for classified-listing specialists, marketers, and businesses managing large catalogs. Google Sheets remains the workspace while the service validates data, synchronizes listings, processes images, and publishes XML.

How the platform works from start to finish
The challenge
Manage hundreds of listings without copying data by hand
A malformed column, duplicate ID, or inaccessible image can disrupt an entire catalog upload. Every update otherwise requires repeated checks and manual XML changes. The service turns that workflow into a controlled pipeline.
Capabilities
A complete bulk-upload preparation workflow
Google Sheets as the source
Specialists work in a spreadsheet while the service normalizes data and maintains current state.
Incremental updates
Only changed listings, descriptions, and images are processed again.
Background media processing
Images are prepared in parallel; one failed file does not stop the catalog.
XML bulk upload
The feed is assembled automatically, stored in object storage, and exposed through a permanent URL.
Multiple clients
Separate cards isolate spreadsheets, settings, storage, and state for every customer.
