What Our Users Say
Been searching for something like this for months. Our Shopify store processes 500+ orders monthly and this handles everything perfectly. Date formats, tax columns, refunds - all correct.
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!!

Validation Questions Answered
What columns are required for QBO customer import?
Only the Name field is required (Display Name As). Optional fields include Company, First Name, Last Name, Email, Phone, and address fields.
Why are duplicate names a problem?
QBO requires unique names across all customers, vendors, and employees. Duplicates in your file will cause import failures.
What happens to my data?
Your file is processed entirely in your browser. No data is uploaded to our servers.
How Validation Works
Issues are flagged inline with clear fix suggestions — review and correct before you import.
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.
Your Data Stays Private During Validation
Every Row Checked
Each record is validated against format rules. Catch errors before they reach your platform.
Runs in Your Browser
Validation happens locally. Your data never leaves your browser.
GDPR Compliant
No files uploaded, no data retained. Full EU privacy compliance.
Why Validate Before Importing?
Name Validation
Checks for required Name field and validates uniqueness.
Duplicate Detection
Identifies duplicate customer names that will cause import errors.
Email Validation
Validates email addresses are properly formatted.
Field Length Checks
Ensures fields don't exceed QBO character limits.
Browser-Based
Files processed locally. Your data never leaves your computer.
Instant Results
Get validation results in seconds, even for large files.

Frequently Asked Questions
Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.
No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
Only the Name field is required (Display Name As). Optional fields include Company, First Name, Last Name, Email, Phone, and address fields.
Name: 100 characters. First/Last Name: 25 characters each. Phone: 21 characters. Street: 41 characters. City: 31 characters.
QBO requires unique names across all customers, vendors, and employees. Duplicates in your file will cause import failures.
Add distinguishing information to the Name field, like 'John Smith (Chicago)' or 'John Smith - Wholesale'.
Your file is processed entirely in your browser. No data is uploaded to our servers.
Special characters like commas and quotation marks can cause import errors. Use simple alphanumeric characters in customer names and fields for best results.
Emails must contain @ and have no spaces or 'mailto:' prefix. Avoid copying emails from messages as hidden characters can make them invalid.
QuickBooks Online adds a 2-digit number to duplicate customer names to make them unique, but you may lose data mapping accuracy.
While addresses aren't required for import, they're needed for credit card processing. Only ZIP code is required for payment validation.
Yes, QuickBooks accepts CSV and XLSX files. Save Excel files as CSV with headers in row 1 and data below.
