Built for operations

Useful before it becomes a workflow

These tools target repetitive catalog and operations tasks. Today each action is free and local. Reusable mappings, batch execution, automation, and APIs will only be built when repeated demand is proven.

Important boundary

Always validate output against the destination system’s current specification. This site is independent and is not certified by a marketplace.

Questions

Before you process a file

Is the header included in every file?

Yes. Every generated part includes the same column header row.

Does splitting change my values?

Values are parsed and re-encoded as UTF-8 CSV. Review a sample before importing into another system.

How many rows can I split?

The practical limit depends on browser memory. This MVP accepts files up to 50 MB and warns before processing larger inputs.
