Google Analytics CSV Analyzer
Summarise a Google Analytics 4 CSV export: column totals, averages and top rows.
What this tool does
Reads a GA4 report export, ignores its comment header lines, detects numeric columns and shows sums, averages, maximums and the top rows by a metric.
Who should use it
Marketers and SEOs who want a quick overview of an export without a spreadsheet.
How it works
Lines starting with # are removed. A column counts as numeric if at least 90% of its values parse as numbers (thousands separators and % are handled). Statistics are plain arithmetic.
How to use it
- Enter or paste ga4 report exported as csv in the form.
- Adjust the options below the main box if you need to; the defaults suit most cases. Use "Load example" to see how input should look.
- Press the run button. Processing happens instantly in your browser.
- Review the result panel, then copy or download the output if the tool offers it. Use Reset to start over.
Practical example
A Landing page report with sessions and engaged sessions returns totals and the ten biggest pages.
Understanding the results
Do not add up rate columns (engagement rate) or distinct counts (users); the notes explain why.
Limitations
It cannot reproduce GA4's own de-duplication of users across rows. Data stays in your browser.
Accuracy and report transparency
Results are computed in your browser from exactly what you enter. Deterministic steps (counting, parsing, encoding, validation) are verified by an automated test-suite with known answers. Where a method is a heuristic, the result panel says "estimated". No external data is used and nothing is invented.
Privacy
Your input never leaves your device for this tool. We count anonymous events (tool opened, run, copied) without storing what you typed. See the Privacy Policy.
Frequently asked questions
Why doesn't my user total match GA4?
Users are de-duplicated across the whole report by GA4; the sum of row values is usually larger.
Is my data sent to your server?
No. This tool runs entirely in your browser, so the text or files you enter stay on your device. We do record anonymous counts of how often each tool is opened or run (no input data) to see which tools are useful.
How accurate are the results?
Counting, parsing, encoding and validation steps are deterministic and covered by automated tests with known answers. Anything based on a heuristic is labelled "estimated" in the result panel.
Is this tool really free?
Yes. There is no account, limit or paid plan. The site is supported by advertising, which is disclosed on our Advertising Disclosure page.
