What Our Users Say
works good, wish it had batch mode
I was spending 4-5 hours every month reformatting exports manually. This tool paid for itself in the first use. The preview feature helped me verify the mapping before paying.
exactly what i needed thx!!
Super straightforward. Upload, convert, download. No account needed which is nice. Would give 5 stars if they add Xero support.
saved me hours of work
My accountant was so happy when I sent her the converted file. No more back-and-forth about date formats or missing columns. Everything imported correctly on first try.
fast and easy 10/10 would recommend
Been using this for 6 months for monthly reconciliations. Handles all the edge cases - partial refunds, multi-line orders, currency conversions. Very reliable tool.
Good tool, does what it says. Interface could be bit better but conversion quality is excellent. Using it for my 3 Shopify stores.
Switched from A2X to this. Way simpler for my needs - I don't need real-time sync, just clean data once a month. This delivers exactly that.
finally!! something that works with QB desktop!!

Why Validate Customer Data?
Name Uniqueness is Critical
QuickBooks Online requires unique customer names across all names
(customers, vendors, and employees). Duplicate names cause import failures.
Validating first identifies duplicates and formatting issues.
What This Tool Checks
We validate your customer CSV against QBO requirements:
- Required Name field present (max 100 characters)
- No duplicate names within the file
- Email format valid (if provided)
- Phone numbers within length limits
- Address fields properly formatted
You get a detailed error report with row numbers to fix issues.
