# Creating Models

> Learn how to create new spreadsheets and clean up messy data

Apers can build spreadsheets from scratch and clean up messy data for you.

## Creating Spreadsheets from Scratch

Tell Apers what you need, and it will build a spreadsheet with dynamic formulas.

**What you can create:**

* Proforma models
* Asset management trackers
* Portfolio management spreadsheets
* Any custom model you describe

<Steps>
  <Step title="Describe your model">
    Type what you want in the Chat box. For example: "Create a multifamily proforma for a 50-unit apartment."
  </Step>

  <Step title="Upload supporting documents (optional)">
    Drag and drop rent rolls, OMs, LPAs, or other documents into the Data Room. Apers will use this information in your model.
  </Step>

  <Step title="Let Apers build">
    Apers will create your spreadsheet with dynamic formulas based on your instructions and documents.

## Using Unstructured Documents

Apers understands scanned and unstructured documents. You can upload:

* Scanned rent rolls
* Offering memorandums (OMs)
* Limited partnership agreements (LPAs)
* Other legal or financial documents

Apers extracts the key information and uses it to build your model.
