PRS CSV Too Big for Excel?

PRS royalty statements for active composers often contain tens of thousands of rows. Excel can technically handle up to about 1 million rows, but it becomes painfully slow long before that — especially when filtering, sorting, or building pivot tables. Google Sheets struggles even earlier. The file isn't broken — your spreadsheet just isn't built for this.

Why PRS Files Break Spreadsheets

Your PRS royalty statement has one row for every single use of every single work in every single territory. If you have 50 registered works, each played in 10 countries, that's 500 rows per quarter — from that alone. Add in BBC, ITV, streaming, radio, live performances, and international collections, and the numbers grow fast.

Active library music and production music composers regularly receive statements with 20,000 to 50,000 rows per quarter. Load a few years and you're looking at hundreds of thousands of rows.

What Happens in Excel

Excel technically opens the file, but then:

And this is for a single statement. Try combining multiple quarters for trend analysis and Excel effectively becomes unusable.

Google Sheets Is Worse

Google Sheets runs in a browser, which means even less processing power and memory available. It has a cell limit of roughly 10 million cells, and performance drops off steeply well before that. Plus you're uploading your private financial data to Google's servers.

The Real Problem

Spreadsheets are general-purpose tools. They're brilliant for budgets, project plans, and shopping lists. They're not designed for analysing tens of thousands of rows of structured royalty data from a specific format.

What you actually need is something that understands PRS statement formats, can handle the volume, and gives you the answers without building formulas and pivot tables every quarter.

What RoyaltyPro Does Differently

RoyaltyPro is a desktop application built specifically for PRS and MCPS royalty statements. Drag in your CSV files — as many as you have, from as many quarters as you've saved — and see your results in seconds.

No row limits. No formulas. No pivot tables. No uploading to the cloud. Your data stays on your computer and the analysis happens locally.

Frequently Asked Questions

Excel supports up to 1,048,576 rows per sheet. But performance degrades well before that — most users notice significant slowness around 50,000-100,000 rows, especially with formulas, filters, or pivot tables applied.

You could, but then you lose the ability to see the complete picture. Splitting by quarter or by work title means you can only analyse fragments of your data. The whole point is to see everything together.

Usually not for large files. Google Sheets has a cell limit (about 10 million cells) and can become very slow with large datasets. It also requires uploading your financial data to Google's servers, which may not be ideal.

RoyaltyPro is built specifically for processing large PRS CSV files. It reads and analyses them locally on your computer without the row limitations or performance issues of spreadsheet software. You can load multiple years of statements at once.
