A SMALL EXAMPLE
Clean structure. Same facts.
Fictional demonstration data.
Not a client project or testimonial.
Prepared output
| SKU | Price | Inventory quantity |
|---|---|---|
| 00001 | 12.5000 | 7 |
| 00002 | 18.00 | 0 |
Leading zeros stay intact. Zero stock stays zero. Prices stay unchanged.
This illustration shows selected columns only. The downloadable demonstration includes five fictional rows and mapping notes. Review CSVs use inert text labels to preserve identifiers when opened in spreadsheets; they are not import files. A file check does not establish compatibility with every store configuration.
HOW IT WORKS
One file in.
A clearer catalog out.
- 01
Send five representative rows
Use a redacted sample you have permission to share. Include your target format and the problem you need fixed.
- 02
Review the sample and scope
We confirm the row count, mapping, missing information, and delivery date before sending a PayPal invoice.
- 03
Receive your files and change report
You get the prepared CSV and unresolved issues. Back up your store and test a small import before applying the full catalog.
Included
Header mapping, explicit variant grouping, consistent field structure, duplicate checks, and source-to-output validation. The pilot covers new products, USD prices, and one inventory location. Excel extraction is reviewed separately before acceptance.
Kept under your control
Prices, stock, identifiers, and publication choices. We flag missing values. Store uploads, copywriting, image sourcing, scraping, and complex migrations are outside this pilot.
Clear terms
Up to 100 rows including variants, one source file, and one revision. Larger or ambiguous files need a new scope. If accepted work cannot be delivered as agreed, we offer a correction or refund. Statutory rights are unaffected.
