Data Maps — Turn Spreadsheets into Visualizations
Visualize your data on a map without code. Connect a Google Sheet or upload a file, then render it as a heatmap, choropleth, cluster, or store locator — and keep it live.
Free to start. No credit card required.
Data maps put the rows of your spreadsheet onto a map so location patterns become visible. Mapji reads your data and renders it as whichever visualization fits — density heatmaps, region choropleths, clustered markers, animated timelines, and more.
Connect a Google Sheet as a read-only, always-live data source and your map updates automatically as the sheet changes. No databases, no pipelines, no code — just your data, mapped.
Spreadsheet to map
Upload a file or connect a Google Sheet and map columns to coordinates and values.
Always live
A Sheets sync keeps your map current automatically — edit the sheet, the map follows.
Many visualizations
Render the same data as a heatmap, choropleth, cluster, time slider, or locator.
Auto column detection
Mapji detects latitude and longitude columns to get you mapped fast.
How it works
Choose a visualization
Pick the map type that fits your data — heatmap, choropleth, cluster, and more.
Connect your data
Upload a file or connect a Google Sheet and map the columns.
Style it
Apply a theme, color scale, and legend.
Publish & embed
Share the live data map or embed it on your site.
Related map types
Heatmap
Visualize data density with smooth heat gradients that reveal geographic patterns at a glance.
Choropleth Map
Color geographic regions by data values to reveal spatial distributions. Perfect for demographic, economic, and election data.
Cluster Map
Group dense markers into clusters that expand on zoom for smooth performance with large datasets.
Time Slider Map
Animate data over time with an interactive timeline. Watch patterns emerge as you scrub through dates.
Frequently asked questions
How do I turn a spreadsheet into a map?
In Mapji, choose a map type, connect a Google Sheet or upload a file, map the columns to coordinates and values, and publish. The map stays in sync with the sheet.
Does the data map stay up to date?
Yes. Connect a Google Sheet as a live data source and Mapji re-syncs automatically, so the map reflects your latest data.
What kinds of data maps can I make?
Heatmaps, choropleth maps, cluster maps, store locators, and time-slider maps — all from the same spreadsheet data.
Can I put my data next to population, land cover or rainfall?
Yes, as background layers. Population density, surface water, precipitation, sea surface temperature, European land cover and more come from the built-in layer catalog, drawn live beneath your own data on any map type. They're for context — the layer isn't imported, so it doesn't count against your data limits.
