# Track changes, but for spreadsheets.

Word has it. Google Docs has it. Your financial models never did — until now. See exactly what changed between any two versions, sessions, or users.

## Use cases

Built for teams where every number has a consequence. The same feature, different stakes. Here's how FP&A and Capital Markets teams put cell-level tracking to work.

### FP&A

Budget cycles, operating models, board decks

“Who changed the revenue assumption before I sent the board deck?”

**Situation**  
CFO review in 2 hours. Revenue is $8M lower than the version you presented last week. You need the answer in 30 seconds, not 30 minutes of Excel forensics.

**What Rockhopper shows**  
Rockhopper's Microsoft Excel Add-in highlights every changed cell directly inside your spreadsheet and surfaces a full change log with quantitative impact — so you see both where it changed and what it cost you.

### Capital Markets

Deal models, investor materials, live transactions

“Did anyone touch the model after I locked it for the management presentation?”

**Situation**  
Your LBO model was locked Monday evening. The management presentation is Tuesday at 9am. You need certainty that no analyst touched the returns table overnight — before it goes in front of the CEO and the sponsor.

**What Rockhopper shows**  
Rockhopper's Microsoft Excel Add-in flags every post-lock edit in red directly on the returns table and surfaces the full change log — including the analyst who made the edit, the exact cells touched, and the IRR impact — before anyone distributes the deck.

## Core features

Four capabilities. One complete picture. Every feature in cell-level tracking exists to answer the same question finance teams ask a hundred times a year: exactly what happened to this number?

### 01 — Full Edit History

**Every change, preserved indefinitely**  
Every change to every cell, preserved indefinitely. Compare any two versions side by side. Never lose a prior assumption, a corrected formula, or an overridden input.

- Side-by-side compare  
- Infinite retention  
- Cell-level diff

### 02 — User Attribution

**Every edit tagged to its author**  
Every edit is tagged to the person who made it — not the file, not the session. Know immediately whether a change came from the Controller, a junior analyst, or an AI agent.

- Per-user tracking  
- Role visibility  
- Agent attribution

### 03 — Materiality Filters

**See only what moves your numbers**  
Set your own dollar or percentage threshold. Filter your change log to show only what crosses it. Stop reviewing every cell. Start reviewing the changes that actually require sign-off.

- Dollar threshold  
- Percentage filter  
- Sign-off routing

### 04 — Timestamp Logging

**Reconstruct how a model evolved**  
Every change carries a precise timestamp — date, time, and sequence order. Reconstruct exactly how a model evolved from first draft to final sign-off. Essential for audit trails.

- Precise timestamps  
- Sequence order  
- Audit trail

## Full edit history in depth

**Every cell. Every version. Side by side.**  
Rockhopper captures a complete cell-level diff every time a version is created — so you can compare any two points in a model's history without opening both files.

- Compare any two versions side by side with changes highlighted inline
- Every changed cell shows the old value, new value, and percentage impact
- Changes are grouped by sheet and section for fast navigation
- Filter by user to see exactly what each contributor touched
- Full version timeline with descriptions and commit context

## Materiality filters in depth

**Filter by what matters. Ignore what doesn't.**  
Not every change deserves a review. Set your materiality threshold — by dollar amount or percentage — and Rockhopper surfaces only the changes that cross it.

- Set thresholds by dollar amount, percentage, or both
- Filter by team member to isolate specific contributors' changes
- Changes below threshold are hidden — not deleted — and always recoverable
- Apply filters to any version comparison, not just the latest
- Export filtered change logs for audit review and sign-off documentation

## Side-by-side comparison

**Two versions. One screen. Every difference highlighted.**  
Rockhopper's split view puts two versions of your spreadsheet next to each other with every change highlighted — so you can verify edits in context without switching between files.

- Side-by-side view of any two versions with inline change markers
- Edit history panel shows the author, timestamp, and cell-level impact for each change
- Navigate between changed cells with a single click
- Works with multi-tab workbooks — every sheet comparison in one view
- Highlighted changes maintain the original spreadsheet formatting and structure

## Conclusion

Rockhopper gives every number in your model a complete, attributed, timestamped history — from first draft to final sign-off. Trust your spreadsheets.
