Data Management Platform
Enterprise data management and collaborative intelligence at scale.
Nsheet is a browser-native data management platform built for teams to unify, govern, and analyze live data in real time. Combine spreadsheet familiarity with database governance, automated pipelines, and immutable audit trails.
Overview
Why Nsheet exists
Most organisations still run their most important numbers in spreadsheets. The problem is never the grid - it is the fourteen copies of the grid, the version nobody can find, and the macro that only one person understands.
Nsheet keeps the familiar spreadsheet surface and fixes everything around it. Every workbook has one canonical copy, a complete revision history, and permissions down to the range. Two hundred people can be in the same sheet without a merge conflict.
It reads and writes .xlsx and .csv faithfully, so migration is an upload rather than a project, and workbooks you send out still open in whatever your counterparties use.

Capabilities
What it does
Real-time co-editing
Presence, cell-level cursors, comments and threaded resolution. Conflict-free edits with no lock-out and no 'file in use' dialogs.
Full formula engine
Over 400 functions including dynamic arrays, LAMBDA, XLOOKUP, QUERY and full cross-workbook references, evaluated server-side for large models.
Pivot tables and charts
Pivots, slicers, conditional formatting and 30+ chart types that stay live against the underlying range.
Data connectors
Pull live rows from Postgres, MySQL, REST endpoints, warehouses and internal APIs on a schedule, with refresh history per range.
Scripted automation
Write typed JavaScript automations against the workbook API, triggered on edit, on schedule or on form submission - reviewed and versioned like any other code.
Governance and audit
Range-level permissions, workbook data classification, immutable revision history and exportable audit logs for every cell change.
Architecture
How it is built
Calculation engine
Rust dependency-graph evaluator that recalculates only the affected subgraph; million-cell workbooks stay interactive.
Collaboration service
CRDT-based document state with per-range access control applied server-side before any edit is broadcast.
Storage
Postgres for workbook metadata and permissions, object storage for revision snapshots, all inside your chosen region.
Automation runtime
Sandboxed script executors with explicit scopes, execution logs and hard timeouts.
Interface layer
Canvas-rendered grid in the browser, plus a documented REST and webhook API for everything the UI can do.
Workflow
A day inside the product
Import
Drop in existing .xlsx, .csv or .ods files. Formulas, formats, named ranges and charts carry over.
Structure
Set the workbook's data class, owners and range permissions once - they follow every copy and export.
Collaborate
Teams edit together with comments, mentions and review requests in the sheet instead of the inbox.
Automate
Replace the manual monthly ritual with a scheduled script, a connector refresh and an approval step.
Report
Publish read-only views and dashboards to stakeholders without giving away the underlying model.
Govern
Audit trails, retention policies and access reviews built into every workbook lifecycle.
Use cases
Where teams start
Financial planning and close
One model, many contributors, and a revision history the auditor can read.
Operations trackers
Live inventory, dispatch and rota sheets fed by connectors instead of overnight exports.
Data collection at the edge
Forms write straight into a governed sheet; field teams never touch the master model.
Analyst workbenches
Warehouse queries land in a sheet where the analysis actually happens, refreshed on a schedule.
Roadmap
What lands next
Shipping now
Offline editing
Full offline grid with deterministic reconciliation when the connection returns.
Next quarter
Formula explain
Plain-language explanations and dependency maps for inherited models nobody documented.
In research
Governed AI assist
Assistance that drafts formulas and cleans data inside your permission boundary, with every suggestion reviewable.
