4 conversion methods at a glance
There are several ways to convert PDF statements to CSV. Here is a quick overview of all the options:
1. Manual entry
Hand-typing each transaction into Excel or Google Sheets.
2. Excel Copy & Paste
Copy text from PDF and paste it into Excel, then format it manually.
3. OCR software
Text recognition with Adobe Acrobat, ABBYY FineReader or similar tools.
4. KontoCSV (AI powered)
Automatic conversion with artificial intelligence – specialized for German banks.
Method 1: Manual entry
The classic method: You open the PDF account statement and manually enter each transaction in Excel or Google Sheets.
This is how it works:
- 1Prepare Excel table: Create columns for date, description, amount, balance
- 2Open PDF: View bank statement in a PDF reader
- 3Type: Transfer each transaction individually
- 4Format: Adjust date format, format amounts as numbers
- 5Save as CSV: "File → Save As → CSV"
Advantages
- ✓ No additional software required
- ✓ Full control over every entry
- ✓ Free
Disadvantages
- ✗ Extremely time consuming (~5 min/page)
- ✗ High error rate due to typos
- ✗ Not scalable for many statements
- ✗ Monotonous, tiring work
When does this method make sense?
Just for individual, short account statements (1-2 pages) or if you need absolute control over each entry. Definitely for regular accounting not recommended.
Method 2: Excel Copy & Paste
Slightly faster than manual entry: Copy text from the PDF and paste it into Excel.
This is how it works:
- 1Highlight text: Mark and copy transactions in PDF (Ctrl+C)
- 2Insert into Excel: Insert text into Excel (Ctrl+V)
- 3Split text into columns: Excel function "data → text in columns"
- 4Edit manually: Correct incorrectly divided lines
- 5Format & Save: Format columns and export as CSV
Advantages
- ✓ Faster than manual entry
- ✓ No additional software
- ✓ Free
Disadvantages
- ✗ Only works with text-based PDFs
- ✗ Formatting is often lost
- ✗ A lot of manual rework required
- ✗ Error prone with complex layouts
Common problem:
Copy & Paste often works for scanned PDFs or PDFs with complex layouts not at all or returns unreadable text.
Tip: If the copied text in Excel looks like "gibberish", the PDF is probably scanned. Then you need OCR software or an AI solution.
Method 3: OCR software
OCR (Optical Character Recognition) recognizes text in scanned PDFs. Known tools: Adobe Acrobat Pro, ABBYY FineReader, Tesseract.
This is how it works:
- 1Install OCR software: e.g. Adobe Acrobat Pro (approx. 18€/month)
- 2Open PDF: Open account statement in the OCR software
- 3Perform OCR: Run “Recognize Text” (takes 1-2 minutes)
- 4Export as Excel: Select “Export → Excel”.
- 5Post-processing: Correct errors, format, save as CSV
Advantages
- ✓ Also works on scanned PDFs
- ✓ Faster than manual entry
- ✓ Professional tools available
Disadvantages
- ✗ Paid (15-30€/month)
- ✗ High error rate with poor quality
- ✗ Not specialized in bank statements
- ✗ A lot of manual rework
- ✗ Complex operation
Important to know:
OCR software is not specialized on account statements. It recognizes text, but does not understand the structure of transactions. This means that amounts are often assigned incorrectly, date formats are mixed up, and columns have to be sorted manually.

Avoid common mistakes
These mistakes happen even to experienced users. Learn how to avoid them.
Mistake #1: Incorrect decimal separators
Problem: Excel interprets "1,234.56" as text instead of a number.
Solution: In Excel under "File → Options → Advanced" set the German number format (comma as decimal separator).
Mistake #2: Umlauts are displayed incorrectly
Problem: Umlauts in words like “transfer” are rendered illegible.
Solution: Save CSV with UTF-8 encoding. In Excel: "File → Save As → Tools → Web Options → Encoding → UTF-8".
Mistake #3: Balance is incorrect
Problem: Ending balance in CSV differs from PDF.
Solution: Check that all transactions have been recorded. Lines are often missing from page breaks. KontoCSV detects this automatically.
Error #4: DATEV import fails
Problem: DATEV does not accept the CSV file.
Solution: DATEV requires specific columns (booking date, sales, debit/credit, etc.). KontoCSV creates files compatible with the German DATEV profile when that workflow is needed.
Frequently Asked Questions (FAQ)
Which method is the fastest?
KontoCSV is significantly faster than manual entry at ~30 seconds per page. OCR software takes ~2 minutes, Excel copy & paste ~3 minutes, manual entry ~5 minutes per page.
Does copy & paste work on all PDFs?
No. Copy & Paste only works with text-based PDFs. The text cannot be copied on scanned PDFs (photos/scans). Then you need OCR software or an AI solution like KontoCSV.
Is KontoCSV GDPR compliant?
Yes, KontoCSV is fully GDPR compliant. All data is transmitted encrypted, processed in Germany and automatically deleted after conversion. No data transfer to third parties.
Which banks are supported?
KontoCSV supports 50+ German banks including Sparkasse, Volksbank, Deutsche Bank, Postbank, Commerzbank, ING, DKB, Comdirect and many more. The AI is specially trained on German bank statements.
Can I convert multiple PDFs at the same time?
Yes, KontoCSV supports batch processing. You can upload multiple PDFs and they will all be converted automatically. When entering manually or Excel copy & paste, you must edit each PDF individually.
