Fix Special Characters and Encoding Issues in Bank Statement CSVs
We Understand Your Confusion
You're facing this scenario: You opened your bank statement CSV in Excel, and the currency symbols look like this:
Instead of: Coffee Shop £4.50
You see: Coffee Shop £4.50
Instead of: Paris Hotel €127.00
You see: Paris Hotel €127.00
Instead of: Café Français
You see: Café Français
Every international transaction looks like encrypted code. Pound signs (£), Euro symbols (€), accented characters (é, ñ, ü) - all gibberish. Your accountant asked for a clean CSV for tax filing, and you're afraid to submit this mess because it looks unprofessional and might be rejected by QuickBooks or IRS software.
You tried re-exporting from your bank, same problem. You tried "Save As" with different formats, made it worse. Now you're considering manually typing the correct symbols, which would take hours for a 200-transaction statement.
This isn't your fault. This is a character encoding problem - your CSV is in UTF-8 (which supports international characters), but Excel opened it as Windows-1252 (which doesn't). Simple fix once you know the trick.
TL;DR - Quick Summary
What Went Wrong
- •CSV is UTF-8 encoded but Excel opened it as Windows-1252
- •Currency symbols (£€¥₹) need UTF-8, don't work in Windows-1252
- •International characters (é, ñ, ü, 日本) corrupted by wrong encoding
- •Excel defaults to system encoding, not file's actual encoding
Quick Fix
- ✓Excel: Use Data → From Text/CSV → UTF-8 encoding
- ✓Notepad++: Encoding → Convert to UTF-8 → Save
- ✓Command line: iconv -f ISO-8859-1 -t UTF-8 input.csv output.csv
- ✓Best solution: EasyBankConvert uses UTF-8 by default
What Causes Character Encoding Problems?
Character encoding tells computers how to convert binary data (0s and 1s) into readable text. When the encoding doesn't match, characters get scrambled. Here's what's happening:
The Encoding Mismatch Problem
Your CSV: Saved in UTF-8 encoding (supports all international characters)
Excel: Opens CSV using Windows-1252 encoding (limited character support)
Example: The British Pound symbol (£) in UTF-8 is stored as 2 bytes: 0xC2 0xA3
When Excel reads this as Windows-1252, it interprets 0xC2 as "Â" and 0xA3 as "£", displaying "£" instead of "£"
Happens when you "fix" the file by saving it again in Excel, which re-encodes already corrupted characters, making it worse.
Original: € (Euro sign in UTF-8)
After wrong open: € (corrupted)
After re-save in Excel: € (double-corrupted)
Some older systems or software don't support certain character sets at all, replacing them with ? or � (replacement character).
Chinese characters (人民币): Shows as ??? in ISO-8859-1
Indian Rupee (₹): Shows as � in Windows-1252
Emoji (💰): Shows as �� or blank
Common Encoding Types and Character Support
Understanding different encodings helps diagnose your specific problem:
| Encoding | Characters Supported | Currency Symbols | Common Issues |
|---|---|---|---|
| UTF-8 | All languages, all symbols (1.1M+ characters) | £€¥₹₽₩₪₦฿₫ (all supported) | None - this is what you WANT |
| Windows-1252 | Western European only (256 chars) | £€$ only (no ¥₹₽) | Excel default - causes £ → £ |
| ISO-8859-1 (Latin-1) | Western European (256 chars) | £$ only (no €¥₹) | Euro symbol missing (shows as ?) |
| ASCII | English only (128 chars) | $ only (no international symbols) | All non-English chars become ? |
| UTF-16 | All languages (like UTF-8) | All supported | CSV tools don't support it |
Common Character Display Issues
Recognize your specific encoding problem by the corruption pattern:
| Intended Character | Corrupted Display | Encoding Mismatch | Fix |
|---|---|---|---|
| £ (Pound Sterling) | £ | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
| € (Euro) | € | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
| € (Euro) | ? | UTF-8 opened as ISO-8859-1 | Convert to UTF-8 |
| é (e acute) | é | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
| ñ (n tilde) | ñ | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
| ₹ (Indian Rupee) | ₹ | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
| ¥ (Yen/Yuan) | Â¥ | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
| 日本 (Japanese) | 日本 | UTF-8 opened as Windows-1252 | Open with UTF-8 encoding |
Troubleshooting Flowchart: Diagnose Encoding Problem
Follow this flowchart to identify and fix your specific encoding issue:
| Step | Check This | If YES | If NO |
|---|---|---|---|
| 1 | Do you see "£" or "€" or "é" patterns? | UTF-8 → Windows-1252 mismatch → See Fix #1 | Go to Step 2 |
| 2 | Do you see "?" instead of currency symbols or accents? | Character set missing → See Fix #2 | Go to Step 3 |
| 3 | Open CSV in Notepad (Windows) or TextEdit (Mac). Do characters look correct there? | Excel opening problem → See Fix #3 | Go to Step 4 (file is corrupted) |
| 4 | Did you already save the file in Excel (after seeing corruption)? | Double encoding corruption → See Fix #4 | Go to Step 5 |
| 5 | Use Notepad++ or command line to check encoding (file -i command). Is it UTF-8? | File encoding is correct, Excel needs proper import → See Fix #3 | Wrong file encoding → See Fix #5 |
Step-by-Step Encoding Fixes
Fix #1: Open CSV with Correct Encoding in Excel
Problem: You see "£" or "€" - UTF-8 file opened with wrong encoding.
This opens it with Excel's default encoding (Windows-1252). Instead, open Excel first (blank workbook).
Why: We need to manually specify UTF-8 encoding
(Older Excel: Data → From Text/CSV or Data → Import Text File)
Why: Opens Text Import Wizard with encoding options
Preview window appears. Look at "File Origin" dropdown at top.
Watch the preview - currency symbols should now look correct (£ instead of £).
Why: This tells Excel to interpret bytes as UTF-8
Characters now display correctly. Save as Excel file (.xlsx) to preserve encoding.
Fix #2: Convert File Encoding with Notepad++
Problem: File is in wrong encoding (ISO-8859-1 or Windows-1252) and needs conversion to UTF-8.
Get from notepad-plus-plus.org. Mac users: Use TextEdit or BBEdit.
Look at bottom-right corner - shows current encoding (e.g., "Windows-1252" or "ANSI").
(NOT "Encode in UTF-8" - that just changes tag, not actual data)
Why: "Convert" transforms actual bytes, "Encode" just relabels
Currency symbols (£€¥) should display properly. If still wrong, source file is corrupted.
Bottom-right corner should now say "UTF-8". File is fixed.
Fix #3: Convert Encoding with iconv (Mac/Linux)
Best for: Technical users on Mac/Linux, bulk conversion of multiple files.
Output shows "charset=iso-8859-1" or "charset=utf-8"
Replace ISO-8859-1 with actual encoding from step 1
Should now show "charset=utf-8"

Frequently Asked Questions
Why are currency symbols showing as gibberish in my CSV?
This happens when CSV encoding (UTF-8) doesn't match what Excel expects (Windows-1252 or ISO-8859-1). Currency symbols like £€¥₹ require UTF-8 encoding because they're outside the basic ASCII character range.
What happens: When opened with wrong encoding, £ becomes "£" (2 characters), € becomes "€" (3 characters). This is because UTF-8 uses multiple bytes per character, and Windows-1252 interprets each byte as separate character.
Fix: Open CSV using Excel's Data → From Text/CSV feature and manually specify "UTF-8" encoding, or convert file encoding using Notepad++ or iconv.
What is UTF-8 encoding and why does it matter for bank statements?
UTF-8 is universal character encoding standard that supports all languages and symbols (1.1 million+ characters). Bank statements need UTF-8 for:
- Currency symbols: £€¥₹₽₩ (British Pound, Euro, Yen, Rupee, Ruble, Won)
- International merchant names: Café, München, José, François
- Accented characters: é è ñ ü ö (common in names and locations)
- Asian languages: 日本 (Japan), 中国 (China), 한국 (Korea)
Without UTF-8, these display as gibberish or ? symbols. Most modern systems use UTF-8 by default, but Excel still defaults to Windows-1252 (1980s standard) causing compatibility issues.
How do I know what encoding my CSV file is using?
Windows (Notepad++): Open file → Look at bottom-right corner → Shows "UTF-8", "ANSI" (Windows-1252), or "UTF-8-BOM"
Mac/Linux (command line):
Output: "text/csv; charset=utf-8" or "charset=iso-8859-1"
Visual check: Open in text editor. If currency symbols (£€¥) look correct → UTF-8. If they're corrupted → wrong encoding or file is already corrupted.
I already saved the file in Excel and now it's worse. Can I fix it?
Probably not from that file - you've created "double encoding corruption." When you save a file with wrong encoding, Excel re-encodes already corrupted characters, making them unrecoverable.
Example of double corruption:
- Original: € (Euro sign, UTF-8)
- After wrong open: € (3 corrupted characters)
- After re-save: € (9 characters, unrecoverable)
Solution: Re-download fresh CSV from your bank and open it correctly this time using UTF-8 encoding. DO NOT save until you verify characters look correct.
Why does Excel use Windows-1252 instead of UTF-8?
Historical compatibility. Windows-1252 was created in the 1980s for Western European languages and became Excel's default. Changing the default now would break millions of legacy spreadsheets.
The problem: Windows-1252 supports only 256 characters (mostly English + Western European accents). UTF-8 supports 1.1 million characters (all languages). Modern bank statements use UTF-8 for international support.
What you can do: Always manually specify UTF-8 when importing CSVs. There's no way to change Excel's default encoding globally, you must do it per-file.
Should I save my fixed file as UTF-8 or Windows-1252?
Always save as UTF-8. It's the universal standard and works everywhere.
UTF-8 advantages:
- Supports all languages and currency symbols
- Backward compatible with ASCII (basic English)
- Required by most modern accounting software
- Web standard (all browsers support it)
How to save in Excel: File → Save As → Click "Tools" button (bottom-left) → Web Options → Encoding tab → Select "Unicode (UTF-8)" → Save. Or save as .xlsx format which preserves UTF-8 automatically.
Will fixing encoding issues affect my transaction amounts or dates?
No. Encoding only affects how letters and symbols are displayed. Numbers, dates, and punctuation (commas, periods, minus signs) are part of basic ASCII and look the same in all encodings.
What encoding affects: Currency symbols (£€¥), merchant names with accents (Café), international text
What encoding doesn't affect: Numbers (1234.56), dates (01/01/2024), calculation results, column structure
