The local-first BI tool that turns Excel/CSV/JSON into
interactive charts and reports.
No cloud uploads. No SQL knowledge required.
Read-only access. Ephemeral memory. Zero footprint.
Wansan treats your source files as Strictly Read-Only. We never modify your original Excel/CSV files. All processing happens in ephemeral memory—close the app, and the data is instantly destroyed.
Updated your data source? No need to re-import. Just click the "Resync" button or restart the app. Wansan hot-reloads the latest file content while keeping your analysis logic intact.
Don't write SQL. Just ask "What's the revenue growth in Q3?". Wansan translates natural language into precise DuckDB queries instantly.
Stop taking screenshots of dashboards. Use our dedicated A4 canvas to layout charts and notes, then export pixel-perfect PDFs for your boardroom meeting.

Named after Shen Wansan, a legendary merchant and mathematician from the 14th century,
renowned for his ability to accumulate and manage immense wealth.
Just as Wansan was the master of commerce in his time,
we built Wansan Studio to help you master your data—privately, locally, and profitably.
Hi, I'm Edward.
This is the first complete product I've built and shipped in my spare time.
I created Wansan Studio because I was frustrated with modern BI tools—they were either too complex or too intrusive.
I poured my nights and weekends into building the tool I always wanted: Private, Fast, and Local.
