Clean Export
Two minutes now so the next messy export takes one message.
First sentence to type
“Clean this export.”
What it does
- Turns a messy spreadsheet or system export into one clean table in the shape you ask for.
- Keeps every row, flags every guess it had to make, and hands back a CSV.
- Writes you a reusable instruction so next time you only paste the export.
What it will not do
- Will not silently fix ambiguous dates or currencies - it asks day-first or month-first, and which currency.
- Will not drop or merge rows without saying so.
Install - three minutes, pick one
- claude.ai, Customize, Skills, Add, Upload skill - upload clean-export.zip. Start here.
- claude.ai, Projects, New project, Instructions - paste everything below the dashed line. Nothing to replace afterwards.
- Claude Code or Cowork - save it as CLAUDE.md in the folder where your exports land.
Needs
Any Claude plan. One export, pasted in dirty (up to about 200 rows; attach the file if bigger).
After this file
The next file comes out the same way, one at a time. The short videos show each one working before it is released.
This file is free and asks for nothing in return - no email, no account. Memory availability differs by plan and account; if memory is not available in yours, the paste-into-a-project version does the same job.
