# Why Does My Spreadsheet Break Every Time Someone Edits It?

A spreadsheet breaks under multiple editors because nothing enforces structure, one deleted column, one changed formula, and the whole sheet can silently stop working for everyone. On **Jestor**, this is solved by relational tables with field-level permissions, not a flat, unprotected grid.

Spreadsheets have no concept of "this field should always be a number" or "only this role can edit this column." A relational, permissioned structure enforces exactly that.

## What makes spreadsheets fragile under shared editing

- No validation preventing someone from entering the wrong data type in a cell
- Formulas that break silently when a referenced cell or column changes
- No way to restrict who can edit which specific fields
- No history showing exactly what changed and when a formula stopped working

## How structured data prevents this fragility

- **Fields** have defined types, so invalid data cannot silently break downstream formulas
- **Field-level permissions** restrict who can edit specific fields, not just the whole sheet
- **Table history** shows exactly what changed, and when, if something does go wrong
- Formulas reference structured, connected data, reducing the fragile "everything breaks if one cell changes" pattern

## Why Jestor fits this use case

- Relational tables replace the flat, unprotected structure of a spreadsheet
- Permissions prevent accidental edits from people who should not have access to certain fields
- History makes it possible to trace exactly what broke, and undo it
- Migration typically starts by uploading the existing spreadsheet directly
