GA4 Export Analyser
Upload a GA4 Explorer or Reports export (CSV / TSV). Analyse channel mix, landing page concentration risk, high-bounce patterns, and conversion efficiency by source. Entirely client-side.
Analytics Intelligence
GA4 reports are hard to compare across periods: the exports are easier to analyse once pulled out.
This analyser accepts the normal GA4 Explorer export format. It auto-detects which columns hold sessions, users, engagement rate, conversions, and revenue, then shows the three analyses most teams want: channel concentration, landing-page concentration, and conversion efficiency by source.

Frequently asked questions
What CSV format does this tool read?
GA4 Explorer or Reports CSV export. Auto-detects columns for sessions, users, engagement, conversions, revenue.
How do I export from GA4?
Any report and Share and Download. Explorer: three-dot menu and Download. Both work.
What is the HHI concentration score?
Herfindahl-Hirschman Index. Measures how concentrated your traffic is across channels. 2500+ = concentration risk, below 1500 = diversified.
Why does channel concentration matter?
If one source carries most traffic, an algorithm change or vendor outage puts the business at risk. Diversification is business continuity.
Does the tool store my CSV?
No. Everything runs in your browser. Nothing uploaded or stored.
What size CSV can I load?
Up to 25MB in-browser. Larger exports: filter in GA4 before downloading.
What is revenue per session?
Revenue divided by sessions for a given dimension. Lets you rank channels by efficiency as well as volume.
How is this different from the GA4 UI?
The UI is interactive but limited by sampling and preset dimensions. This tool runs on raw export, no sampling.
Can I compare two periods?
Not in one load. Export both periods separately, run twice, compare the outputs.
Does it work with GA4 free-form reports?
Yes. Any CSV export with sessions and dimensions works. The tool infers columns.
What about engagement rate interpretation?
GA4's engagement is the inverse of UA bounce rate. Higher is better. Compare to the 55% to 65% site-wide average.
