# Code Execution & File Creation

> Control whether Agents can analyze data, generate files, and process large connector results by writing and running code.

**Code Execution & File Creation** lets an [Agent](/agents/overview) write and run code when a request needs more than a normal text response. Agents use it to analyze spreadsheets, generate charts, create downloadable files, and work with large results from [Connectors](/agents/connectors/overview) or [Workflows](/workflows/overview).

New custom Agents have **Code Execution & File Creation** enabled by default.

<Info>
  If you're looking for Data Analysis, it has moved into this setting. Data
  analysis is one of the main things Code Execution & File Creation enables.
</Info>

## What it enables

When this setting is on, your Agent can:

* Analyze CSVs, spreadsheets, and structured files
* Create charts, summaries, and calculations from data
* Generate downloadable documents, spreadsheets, presentations, and PDFs
* Read large Connector or Workflow results that would otherwise be cut off
* Work with files attached in Chat or referenced from the [Knowledge Base](/knowledge-base/overview)
