SPREADSHEETS, ANALYTICS & FINANCIAL WORKFLOWS
OneeSheet brings spreadsheet editing, calculations, data preparation and financial review into a connected workspace. Its sparse C# workbook engine runs through a browser WebAssembly worker, with a canvas-based grid and an authoritative collaboration server. The public web workspace supports sign-in and local editing. Oneewaee’s ongoing engineering extends the platform with durable recovery, reusable data refresh and reviewable business workflows.

PRODUCT FEATURES
Explore the features of OneeSheet and the work they help you do.
A sparse workbook model and dependency graph connect formulas across sheets. Calculation runs in a C# WebAssembly worker, separately from the browser interface.
A canvas-based worksheet supports familiar spreadsheet interaction alongside analysis tools that turn raw rows into navigable reports.
Import and export workflows preserve supported workbook features and expose compatibility limits before a file is used for reporting.
SignalR collaboration connects shared edits to server-owned workbook state. Local device checkpoints retain a working copy and pending edits across interruptions.
Development includes explicit preview and publication of CSV and HTTPS API data, with reusable transformation definitions and refresh receipts.
Review-oriented engineering connects approvals to the figures reviewed, and introduces managed invoice and credit posting with protected records.
Optional Hub infrastructure separates account and permission metadata from workbook cell calculations and connects storage to server-managed access.
BEHIND THE INTERFACE
Editing one cell can affect formulas across a workbook. OneeSheet tracks those dependencies, handles dynamic references and isolates formula errors instead of treating each displayed value as an independent text field.
SkiaSharp rendering and a bounded viewport cache keep the worksheet separate from ordinary page elements. WebAssembly workers own workbook operations; the interface displays the resulting state.
Our reliability work uses ordered writes, checksummed edit journals and controlled recovery. Duplicate and interrupted operations need to retain their identity so reconnecting does not create a second business action.
Approval records preserve the exact typed values and source context reviewed. The live workbook can change through other inputs; comparison makes that divergence visible. Integrity hashes are application controls, not external digital signatures.
Import preservation, editable features and calculation support are different capabilities. The Compatibility Inspector explains these distinctions; full Microsoft Excel parity and independent numerical certification are not claimed.
FROM SETUP TO EVERYDAY USE
Open the public local editor for device-based work, or sign in to a configured organization workspace for stored files and sharing.
Import or create the sheets, confirm formulas and compatibility, then prepare data, reports and review steps around the actual business task.
Scope sharing, source refresh, financial controls and recovery with the organization. Confirm the modules enabled in the deployed workspace.
IMPORTANT DETAILS
STRAIGHT ANSWERS
The public site offers a local editor as well as sign-in. Local work is device-based; organizational storage and sharing require a configured account and workspace.
No universal compatibility claim is made. Supported features, preserved package parts and unsupported formulas are distinguished by the Compatibility Inspector. Validate the specific workbook and reporting requirements.
The public sign-in page supports secure links from OneeCRM and Oneemail. Integration behavior depends on the configured application and organization; private account content is not exposed by the company website.
Our work includes calculation fidelity, durable synchronization, bounded rendering, workbook recovery, data provenance and preserved financial approvals. The research and development page explains the methods and remaining validation work.
