Why do my CSV exports from different accounting systems have incompatible date formats?

Different platforms use different regional or ISO date defaults. QuickBooks may export MM/DD/YYYY while a bank portal uses YYYY-MM-DD. This tool normalizes all columns to a single output format so they are compatible for merging or comparison.

Will this tool fix amounts that are formatted as text instead of numbers in my CSV?

Yes. Numeric normalization rewrites values to a consistent numeric representation, which most spreadsheet tools will then correctly interpret as numbers rather than text when you import the CSV.

Can I process multiple CSV exports at once?

Yes. You can upload multiple CSV files in one session. Each file is processed independently and the normalized versions are available for download.

Is my financial data stored after processing?

Deliteful processes your files server-side and does not retain your data after your session. Your original uploaded files are never modified.

Fix CSV Date and Number Formats Before Reconciliation

Exported CSV reports from accounting software, banks, and payment processors rarely agree on how to format dates and numbers — and reconciling them manually wastes hours better spent on review. Deliteful's CSV Normalize Data Types tool standardizes numeric and date columns across all your exported CSVs so they match and merge cleanly.

Accountants and CPAs regularly pull transaction exports from QuickBooks, Xero, Stripe, and bank portals only to find that dates appear as '12/31/2024' in one file and '2024-12-31' in another, and that amounts are formatted with or without commas and currency symbols. When you paste these into a reconciliation spreadsheet, Excel treats them as text rather than numbers or dates, breaking SUM formulas and date-range filters. The fix is normalizing the source files before merging — not reformatting cells by hand after the fact.

This tool processes your exported CSVs and rewrites numeric and date columns to a consistent format you choose. It runs auto-detection across a sample of rows so you don't need to name every column, though you can specify them explicitly for full control. The output is a clean CSV that drops into your reconciliation workbook without any manual cell formatting.
