Shopify CSVs, checked before you import
I audit and clean up Shopify product CSVs, so duplicate variants, broken prices and bad image links are caught before they reach your store. I fix only what has one right answer, and I never invent product information.
- Audit from CHF 49, paid after delivery
- 39 checks
- 2–9 working days
| Handle | Variant Price | Variant Grams | |
|---|---|---|---|
| Before | oak tray | 48,00 | 1.2 |
| After | oak-tray | 48.00 | 1200 |
What breaks imports
These are real messages from Shopify’s import. Each one stops rows or the whole file.
- Shopify says:
Validation failed: options are not unique - What’s behind it: Two variants share the same option values, or one handle appears twice in the file.
- Shopify says:
Validation failed: price can’t be blank - What’s behind it: A variant row has no price.
- Shopify says:
Ignored line … because handle … already exists - What’s behind it: Two different products use the same handle.
- Shopify says:
Ignored line … because it did not contain product data - What’s behind it: A row has a handle but no title.
- Shopify says:
Illegal quoting on line … / Missing or stray quote on line … - What’s behind it: The file isn’t UTF-8, or it contains curly quotes.
- Shopify says:
Invalid CSV header: missing headers - What’s behind it: The header row doesn’t match Shopify’s format, sometimes only because of a trailing space.
- Shopify says:
Validation failed: An error occurred while trying to download the image - What’s behind it: The image link isn’t a direct public link, for example a Dropbox or Google Drive share link.
Worse: the errors Shopify doesn’t report
Weights typed in kilograms into the grams column. Prices with a decimal comma. Barcodes that Excel turned into 8.40127E+11. The file imports, and the data in your store is wrong.

Start small: the Basic fee is fully credited if you book Standard or Premium within 14 days.
Free re-check: after your own edits, I check the file once more, within 14 days.
What counts as a row? Every line in the file. In a Shopify CSV each variant and each extra image has its own row, so 100 products can easily be 300 rows. The free checker shows your row count.
Example: Hollow Pine Goods, 89 rows → Basic CHF 49 · Standard CHF 119 · Premium CHF 169.
Prices in CHF. I’m not VAT-registered, so no VAT is added.

Three severity levels
- Blocking
- The import fails or the row is skipped.
- Will import wrong
- It imports, but the data ends up wrong.
- Cleanup
- It works, but it’s messy.
What I don’t do
- I don’t log in to your store.
- I don’t import anything for you.
- I never invent product information. Missing titles, prices or weights go on your decision list, with the exact rows.
- I can’t guarantee a successful live import. Your store settings, apps and existing products affect it too. I check against Shopify’s documented CSV format and tell you anything I couldn’t check.
- App columns, metafields, subscriptions, bundles and multi-location inventory are reviewed only if the offer includes them.
Your data
- The free checker never uploads your file. It runs in your browser.
- For a paid audit, you send the file by email or with a share link you control.
- I use it only for your project and never share it.
- I don’t put it into AI tools without your OK.
- I delete it 30 days after the project ends.
- You can remove columns like cost per item before sending. I don’t need them.
How an audit works
- Step 1
Free check and inquiry
Check your file with the free checker, if you like. It shows your row count. Then send an inquiry with the row count and what you’re importing.
- Step 2
Fixed price
I reply within 24 hours with a fixed price and delivery date.
- Step 3
Your file, my report
You send the file, after accepting the offer. You get the report, and with Standard or Premium the corrected file.
- Step 4
Your decisions
You make your decisions. I re-check your edits once for free within 14 days.
Payment
- Basic: you pay once, after you’ve received the report.
- Standard and Premium: 50% to start. You get the audit report and a preview of 10 corrected rows. The other 50% releases the full corrected file, QA report and change log.
- By invoice. Swiss clients pay with a QR-bill, international clients by bank transfer in EUR, USD or GBP. No card details on this website.
Not a Shopify file?
Supplier price lists and other Excel or CSV files: same row bands, quoted after I see a 20-row sample.
Questions about product data
Is my CSV safe with you?
The free checker never uploads your file: everything runs in your browser. For a paid audit you send me the file by email or a share link you control. I use it only for your project, never share it, don’t upload it to AI tools without your OK, and delete it 30 days after the project ends. You can remove columns like cost per item before sending.
Will my import definitely work afterwards?
I check the corrected file against Shopify’s documented CSV format and re-run all my checks on it. I can’t guarantee a successful live import, because your store settings, apps and existing products also affect it. I’ll tell you anything I couldn’t check. More in my project terms.
Do you need access to my store?
No. I only work with the files you send me. I don’t log in to your store and don’t import anything for you.
Some product information is missing. Will you fill it in?
No, I never invent product information. Missing prices, weights or descriptions go on a list of decisions for you, with the exact rows. With Premium, I apply your answers for you.
What counts as a row?
Every line in the file. In Shopify CSVs each variant and each extra image has its own row, so 100 products can be 300 rows or more. The free checker shows your row count.
Which files do you work with?
Shopify product CSVs, plus Excel files (.xlsx) and other CSVs, such as supplier lists, on request.
Do I really pay for Basic only after delivery?
Yes. You get the report first and the invoice with it. If you then book Standard or Premium within 14 days, the Basic fee is credited in full.
You’re 18 and still in school. Why should I hire you?
Fair question. I’m new, so I can’t show you years of client work. That’s why my first three projects are at founding rates. What I can show you: this website and how I built it, two concept projects, and a free tool you can test right now.
I take one project at a time and give you a fixed delivery date before you pay anything. For Basic you pay only after you’ve received the report. For Standard and Premium you see the audit report and 10 corrected rows before you pay the second half.
Do you use AI?
Yes, for parts of the work: drafting code, checking for mistakes, speeding up repetitive steps. Not for everything, and never unchecked. I review and test every result myself before you see it. I don’t put your files or customer data into AI tools without asking you first.
How do I pay? Is it safe?
By invoice. You never enter card details on this website. Swiss clients pay by bank transfer with a QR-bill. International clients pay by bank transfer in EUR, USD or GBP to my Wise account. Basic: you pay once, after you’ve received the report. Standard and Premium: 50% to start, 50% before you get the full corrected file.
Is there a contract?
Yes. You get a written offer with scope, price, delivery date, what’s not included and payment terms. My project terms apply, and you can read them before you ask. Accepting the offer by email is enough to start. Read the project terms.
How does communication work, and in which language?
By email, in English or German. A short video call is possible if you prefer. You always deal with me directly: no team, no middleman.
Not sure what your file needs?
Run the free checker first, or send me the row count. I’ll recommend a package.
