Invoice data entry is the same problem whether you use Excel or Google Sheets. An invoice arrives — as an email, a PDF, or a paper scan. You need to get the vendor name, amount, date, tax, and invoice number into rows and columns. Manually, that means opening each invoice, finding the numbers, and typing them in.
The good news: there are tools for both spreadsheets. The approach depends on where your invoices live (email, files, or paper), which spreadsheet you use, and how much you want to automate.
4 ways to convert invoices to a spreadsheet
Excel's built-in PDF import
If your invoices are PDF files on your computer, Excel can import them directly. Go to Data → Get Data → From File → From PDF. Excel detects tables in the PDF and lets you select which ones to import. It works surprisingly well for clean, table-formatted invoices.
The limitation: it only works with PDFs you've already downloaded. If your invoices arrive by email, you still need to open each email, save the PDF, then import it. And it doesn't handle email-body invoices at all — only PDF files. No automation: you repeat this process for every invoice.
PDF-to-CSV converters (Tabula, Camelot)
Free tools like Tabula (desktop app) and Camelot (Python library) extract tables from PDFs into CSV format. Open the CSV in Excel or import it into Google Sheets.
These work well for invoices with clear table layouts. They don't work on scanned documents (images), and they require manual processing per file. Good for occasional use — not for processing 30 invoices every month.
Cloud document parsers
Services like Parsio, Docparser, Nanonets, and Airparser accept invoices (via email forwarding or upload), extract structured data using AI or templates, and push the results to Google Sheets or export as CSV/XLSX for Excel.
These handle the most formats and integrate with both spreadsheets. The trade-offs: your documents route through third-party servers, pricing is per-document ($30–50/mo for 100–200 invoices), and AI-based parsing burns credits faster than template-based extraction.
Best for teams processing a high volume of varied document types and needing output in multiple formats.
Gmail invoice scanner
If your invoices arrive by email (most do for small businesses), a Gmail-native tool skips the download/upload step entirely. Chrome extensions like Clara and cloudHQ sit inside Gmail, scan your inbox for invoices from vendors you specify, and extract the data straight to Google Sheets.
Clara (disclosure: I built it) extracts up to 16 fields per invoice using AI — vendor name, amount, date, due date, tax, billing period, invoice number, and more. It reads both email body invoices and PDF attachments. The first scan per vendor uses AI to learn the format, then caches patterns so future scans are faster and cheaper.
For Excel users: Clara outputs to Google Sheets, which you can download as .xlsx anytime (File → Download → Microsoft Excel). If your workflow is Excel-based, this gives you automated extraction with a one-click export to Excel format.
Excel vs Google Sheets for invoice tracking
Both work. The choice depends on how you work, not the data.
| Excel | Google Sheets | |
|---|---|---|
| PDF import | Built-in (Get Data → From PDF) | No native support |
| Gmail integration | Requires third-party tools | Native (Apps Script, extensions) |
| Collaboration | OneDrive / SharePoint | Built-in, real-time |
| Automation tools | Power Query, VBA, Power Automate | Apps Script, Chrome extensions |
| Offline access | Full | Limited |
| Best for invoices from | Downloaded PDF files | Gmail (email-based) |
The short version: If your invoices arrive as email and you work in Google Workspace, Sheets has better automation options. If you receive PDFs via other channels (postal mail scans, vendor portals, file transfers) and work in Microsoft, Excel's PDF import is the fastest manual option. You can always export between the two.
Which method should you pick?
A few PDFs on your desktop, Excel user: Excel's built-in PDF import. Free, no extra tools.
Occasional batch of PDFs, any spreadsheet: Tabula exports to CSV, which both Excel and Sheets can open.
100+ invoices from many sources and formats: Cloud parsers (Parsio, Nanonets) handle volume and export to both formats.
Invoices arrive in Gmail, want it automated: A Gmail scanner like Clara. Data goes straight to Google Sheets — download as .xlsx if you need Excel. Free for 25 emails/month.

FAQ
How do I convert an invoice PDF to Excel?
Open Excel, go to Data → Get Data → From File → From PDF. Select the table you want and import. For email invoices, use a parsing tool to extract data first, then export as CSV or XLSX.
Can I automatically send invoice data to Google Sheets?
Yes. Gmail-based tools like Clara scan your inbox and write invoice data directly to Sheets. Cloud parsers like Parsio and Nanonets also integrate with Sheets. Apps Script can do it for free if you write the code.
Should I use Excel or Google Sheets for invoice tracking?
If your invoices come via Gmail and you want automation, Google Sheets has better integration options. If you work with downloaded PDF files and use Microsoft Office, Excel has built-in PDF import. For most small businesses, the difference is minor — pick whichever you already use.
Is there a free way to convert invoices to a spreadsheet?
Yes. Excel's PDF import is included with Microsoft 365. Tabula is free and open source for PDF table extraction. Clara's free tier handles 25 Gmail invoices per month into Google Sheets. Apps Script is free with a Google account.
Disclosure: I built Clara, one of the tools mentioned above. The guide covers all methods honestly, including free alternatives.
