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 Bank CSV Files?
Bank Formats Vary Widely
Every bank exports CSV files with different column names and formats.
Chase uses "Transaction Date", Bank of America uses "Posted Date",
and Wells Fargo uses "Date". Amount columns vary even more.
Our validator auto-detects common column names and validates data quality.
What This Tool Checks
We validate your bank CSV against common transaction schemas:
- Date column detected and formats valid
- Amount column detected with proper numeric values
- Description/payee information present
- No empty rows or corrupted data
- Consistent data types across rows
You get a detailed error report with row numbers to fix issues.
Common Target Import Errors
Issues you might encounter when importing Source data to Target - and how we solve them
Missing Date Column
No date column detected in the CSV file
File without Date, Transaction Date, or Posted Date column
Add a column named 'Date' or 'Transaction Date'
Bank exports should include a date column
Re-export from bank ensuring date is included
Missing Amount Column
No amount column detected in the CSV file
File without Amount, Debit, Credit, or Total column
Add a column named 'Amount' or separate Debit/Credit columns
Bank exports should include transaction amounts
Re-export from bank ensuring amounts are included
Invalid Date Value
A date value cannot be parsed
13/45/2025 or pending
01/15/2025 or 2025-01-15
Dates must be in a standard format
Check if Excel reformatted dates incorrectly
Invalid Amount Value
An amount value is not numeric
pending or N/A
-50.00 or (50.00)
Amounts must be numeric values
Filter out pending transactions before export
Empty Row Detected
Row has no data in key columns
Row with only blank cells
Remove empty rows before validation
Empty rows may cause import issues
Clean up the CSV by removing blank rows
Inconsistent Amount Signs
Mix of positive amounts for both debits and credits
All amounts positive with no debit/credit indicator
Negative for debits, positive for credits (or vice versa)
Amount signs should consistently indicate direction
Check if separate debit/credit columns should be used

Frequently Asked Questions
We support CSV exports from all major US banks including Chase, Bank of America, Wells Fargo, Capital One, Citi, US Bank, PNC, and most regional banks. Column names are auto-detected.
At minimum, a valid bank CSV needs a date column and an amount column. Description/payee is optional but recommended. We auto-detect various column naming conventions.
Banks use different date formats (MM/DD/YYYY, YYYY-MM-DD, etc.). If dates fail validation, check if they were modified after download or if Excel reformatted them.
The validator checks for common aliases. If columns aren't detected, you may need to rename them to standard names like Date, Amount, Description.
