What it actually does

Phone normalizationDetects already-international numbers (kept as-is) and prepends the right country code for local numbers, using the customer's billing country.
State and province mappingUS states pass through as 2-letter codes. Every other country gets the full province name Meta requires (England, Bayern, Île-de-France, and so on).
Audience valueShopify's Total Spent column is dropped into Meta's value field for value-based lookalikes.
Header remappingOutputs Meta's exact header set: email, phone, fn, ln, zip, ct, st, country, value, with placeholders left blank where Shopify has no data (madid, dob, gen, age, uid).

FAQ

Do you store my customer data?No. The CSV is parsed in memory on a serverless function, converted, and streamed straight back to your browser. We never write the file to disk and we don't log row contents.

Why is the free tier limited per IP?To stop abuse without forcing you to sign up. Three small free conversions per network is enough to verify it works on your real data, then unlock unlimited rows for $5.

What does Meta do with the value column?Meta uses purchase value to build value-based lookalike audiences — they bias the lookalike toward customers who spend more, which usually outperforms a flat customer-list lookalike.

Why are some phone numbers dropped?Meta requires country codes. If a customer's phone number isn't already international and we can't infer their country code from the billing address, we leave the phone field blank rather than send something invalid.

Will this work for non-Shopify stores?Right now it expects Shopify's standard customer export columns. If you'd like other source formats supported, get in touch.
