# Overview

Spreadsheets are essential tools for finance and accounting teams. They're flexible, powerful, and deeply embedded in workflows — but as teams grow and complexity increases, they start to break down. Versioning becomes unclear, changes go untracked, and reviews happen over email or chat with no formal record.

Rockhopper fixes this. The platform integrates directly with **Microsoft Excel** and **Google Sheets**, connecting to your existing file systems (OneDrive, SharePoint, and Google Drive) so you can keep working in the tools you already use — with structure, oversight, and confidence layered on top.

## What Rockhopper does

### Version control

Every change to an enrolled spreadsheet is tracked. You can view a detailed change log across cells, tabs, and workbooks, and understand exactly who changed what and when.

### Change tracking and auditing

Go beyond knowing what changed — understand *why* it changed. Rockhopper tracks dependencies, assumptions, and context alongside every edit.

### Formal review and approval

Replace email chains and side conversations with structured review workflows. Request reviews from teammates, track approvals, and maintain a complete record of who signed off on what.

### Progress and accountability

See which files have uncommitted changes, who's working on what, and whether reviews are pending or complete. Nothing falls through the cracks.

## Common use cases

Rockhopper supports spreadsheet workflows where alignment, trust, and accuracy matter most:

* **Cash flow rollforwards** — Critical daily updates with high visibility and assumption sensitivity
* **Consolidation schedules** — Managing inputs across multiple business units or entities
* **Intercompany eliminations** — Tracking adjustments and reducing duplication
* **Flux / variance analysis** — Connecting drivers and explanations to changes over time
* **Project finance models** — Coordinating updates across complex, multi-phase scenarios
* **Journal entry tracking** — Ensuring accuracy and alignment of manual entries
* **Reconciliation schedules** — Validating data and assumptions across systems

## Supported platforms

Rockhopper works with the tools your team already uses:

| Platform      | File storage         | Spreadsheet editor        |
| ------------- | -------------------- | ------------------------- |
| **Microsoft** | OneDrive, SharePoint | Excel (desktop, web, Mac) |
| **Google**    | Google Drive         | Google Sheets             |

You don't need to move files or change your workflow — Rockhopper connects to your existing cloud storage and layers version control, change tracking, and reviews on top.

## How it works — the quick version

1. **Enroll** a spreadsheet from OneDrive, SharePoint, or Google Drive
2. **Work normally** in Excel or Google Sheets — Rockhopper tracks every edit automatically
3. **Review changes** in a visual diff that highlights exactly what changed, who changed it, and when
4. **Commit versions** when you're ready to create a formal checkpoint
5. **Request reviews** from teammates for structured sign-off before finalizing

Everything is connected: comments reference specific cells and versions, reviews tie to uncommitted changes, and the full history is always one click away.
