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!!
