# LeadDoubler spreadsheet format

Basics on the structure of our LeadDoubler spreadsheet format.

All [landing pages](https://docs.leaddoubler.com/article/calculator-editor-overview#Preview) in LeadDoubler have an associated spreadsheet. This spreadsheet is used to define:

**Input fields**: These are cells where users can enter data.

**Output/result fields**: These are cells where the calculated results are displayed.

**Calculations**: These are the formulas or operations performed on the input to produce the output.

If you have an existing spreadsheet, you can use our "Builder tool" ([https://build.leaddoubler.com](https://build.leaddoubler.com/)) to quickly and easily convert it into the correct LeadDoubler format. This tool simplifies the process, allowing you to create your calculator more efficiently.

For LeadDoubler to correctly interpret a spreadsheet, it must be formatted in a specific way. An example of this formatting is shown in the following image:

## Spreadsheet Structure

* * *

A spreadsheet in LeadDoubler is divided into two sections:

**Input section** 🟦: Where users enter data.

**Output section** 🟩: Where the results of the calculations are displayed.

These sections are separated by the term '**Calculate 🟥**'. A visual representation of this structure is shown in the following image:
