Why Do My CSVs Have Broken Characters?
If you've ever seen text like Renée instead of Renée, you've been a victim of encoding mismatch. Excel often saves CSVs in an older format called "ANSI" (Windows-1252), which cannot handle international characters.
Standard Excel Export
Name: Renée
Price: €50.00
Status: 🚀 (Broken)
Without a BOM (Byte Order Mark), web apps guess the wrong language.
Our UTF-8 Converter
Name: Renée
Price: €50.00
Status: 🚀 (Preserved)
We enforce UTF-8 with BOM, ensuring Shopify, Xero, and SQL read it correctly.
Pre-Export Checklist: Is Your File Ready?
No Merged Cells
CSVs cannot carry merged cells. Unmerge everything before converting to prevent data shifting.
Single Header Row
Ensure your first row contains unique column names (e.g., 'Email', 'First Name'). Remove pure title rows.
Remove Formulas
Our tool extracts the *value*, but it's safer to Paste Values in Excel first if you have complex macros.
Check Dates
Standardize dates to YYYY-MM-DD for the best compatibility with SQL databases.
Frequently Asked Questions
How is this different from 'Save As CSV' in Excel?
Excel often uses legacy encodings (like ANSI) instead of standard UTF-8, which breaks special characters. Our tool guarantees a clean, UTF-8 formatted CSV that works everywhere.
Does it convert all sheets in my Excel file?
Currently, the converter processes the first active sheet in your workbook. This handles the majority of use cases for data imports.
Is my data private?
Yes! We use client-side processing. Your financial data, customer lists, or personal info never leaves your browser.
Can I import the CSV into QuickBooks?
Yes, the standard CSV output is fully compatible with QuickBooks Online, Xero, Shopify, and almost any other software that accepts CSV imports.
