Invoices arrive as PDFs. Bank statements download as PDFs. Employees photograph receipts on their phones. Before any of that data can live in a spreadsheet or accounting system, it needs to be extracted from the document — and doing that manually is one of the biggest time sinks in small business accounting.

This guide covers how to convert any accounting document to Excel for free, what accuracy to expect, and how to get the output into your accounting software.

Step-by-Step: Convert Any Accounting Document to Excel

Step 1 — Go to the right CleanTably page for your document type

CleanTably has document-type-specific converters that are tuned for each format:

If you're not sure which category fits, use the general accounting converter. The AI identifies document type automatically and adjusts its extraction approach accordingly.

Step 2 — Upload your document

Drag and drop your file onto the dropzone, or click to browse. Accepted formats: PDF, JPG, PNG, WEBP, and HEIC. No account required, no installation.

File size limit is 20MB. Multi-page PDFs are supported up to 20 pages. If your bank statement is longer than 20 pages, split it first using a free tool like PDF24 or Smallpdf.

Step 3 — Wait 5–15 seconds

The AI reads your document, identifies the structure (table rows, headers, totals), and extracts the data. You'll see a progress indicator. Don't close the tab during processing.

Step 4 — Download the .xlsx file

The download starts automatically when extraction is complete. Open the file in Excel or Google Sheets. Columns are labeled, numbers are formatted as numbers (not text), and the data is ready to use.

What Document Types Work Best

The cleaner and more structured the document, the better the output:

  • Digital invoices (PDF from software): 95–99% accuracy. These are the easiest — consistent layout, clean fonts, digital text.
  • Digital bank statements: 95–98% accuracy. Highly consistent row structure makes extraction reliable.
  • Scanned invoices and receipts: 85–92% accuracy depending on scan quality. Higher resolution = better results.
  • Phone photos of paper documents: 80–88% accuracy. Works well in good lighting with the document flat and in frame.
  • Handwritten documents: 60–75% accuracy. CleanTably can handle handwriting but this is the most error-prone category — always review manually.

How to Clean Up the Output in Excel

Even with high accuracy, some post-processing is usually needed. Here are the most common issues and how to fix them:

Numbers formatted as text: Select the column, click the warning triangle, and choose "Convert to Number." Or use =VALUE() in a helper column.

Dates in wrong format: Select the date column and apply a date format via Format Cells > Number > Date. If dates imported as text strings, use =DATEVALUE() to convert.

Extra rows (headers/footers): Delete any rows that contain page numbers, document titles, or other non-data text. These sometimes appear at the top or bottom of multi-page documents.

Merged cells: If a cell spans multiple rows, use Unmerge Cells and fill down to get each row in its own cell.

Why Copy-Paste Doesn't Work

If you've tried copying data from a PDF directly into Excel, you've seen what happens: columns merge into one cell, numbers become text, rows get scrambled. This is a fundamental property of the PDF format — PDFs store drawing instructions, not structured data. There's no table structure to copy, only characters at coordinates. CleanTably reconstructs the structure using AI analysis rather than copying raw text.

How to Import the Excel File into Accounting Software

QuickBooks Online

Settings > Import Data > select Bank Transactions or Expenses. Format your columns to match QuickBooks' template: Date, Description, Amount (or separate Debit/Credit columns). QuickBooks will show a mapping screen where you can match your columns to its fields.

Xero

Accounting > Bank Accounts > Import a Statement. Export your Excel as CSV first (File > Save As > CSV). Xero accepts CSV with columns: Date, Amount, Payee, Description, Reference.

Wave

Wave supports CSV import under Banking > Connect or Import. The expected columns are Date, Description, and Amount. Use the Excel output as a reference for manual entry if direct import doesn't match Wave's format.

Google Sheets

Drag the .xlsx file directly into Google Drive or use File > Import in an open Sheets document. Google Sheets opens .xlsx files natively with full formatting preserved.

Frequently Asked Questions

What accounting documents can I convert to Excel?

CleanTably handles invoices, receipts, bank statements, expense reports, purchase orders, credit card statements, and general financial documents. It works on both digitally generated PDFs and scanned or photographed paper documents.

How accurate is the data extraction?

Overall accuracy on production data is approximately 89%. For clean, digitally generated PDFs (software-generated invoices, digital bank statements), accuracy is typically 95–99%. Scanned documents and phone photos of paper are lower but still significantly faster than manual entry. Always spot-check the first few documents of a new type.

Can I convert scanned documents to Excel?

Yes. CleanTably uses AI-powered extraction that works on scanned documents, phone photos, and low-quality images — not just digitally generated PDFs. Accuracy is lower on poor-quality scans, but it handles the vast majority of real-world document quality without issue.

How do I import the Excel file into QuickBooks?

QuickBooks supports importing transactions from Excel using the Import Data feature under Settings. Format your Excel file with columns matching QuickBooks' expected fields (Date, Description, Amount), then use Settings > Import Data > Bank Transactions or Expenses. Alternatively, use the Excel output as a reference while manually entering transactions.
