# Data Overview

## What data can you import from OneDrive?

OneDrive is a file storage service, so the data you can import depends entirely on what's in your Excel files. Coupler.io treats each Excel file as a data source and pulls the contents of any sheets you specify.

## How it works

When you connect an Excel file from OneDrive, you choose:

1. **Which file** — The specific Excel workbook in your OneDrive
2. **Which sheet(s)** — One or more tabs/sheets within that workbook
3. **Which range** (optional) — A specific cell range, or leave blank to import everything

The data is then synced to your destination on your schedule.

## Data structure

OneDrive Excel files typically have:

* **Headers** — The first row usually contains column names
* **Data rows** — The rows below headers contain your actual data
* **Multiple sheets** — You can consolidate data from different sheets using the Append transformation

## Common use cases

### Marketers

Sync campaign performance data from an Excel tracking sheet in OneDrive to a live Google Sheets dashboard. Pull metrics like impressions, clicks, and conversions, then send them to Claude for automated performance summaries.

### Finance teams

Import expense reports or budget tracking spreadsheets from OneDrive to BigQuery for centralized analysis. Use the Append transformation to combine multiple team budgets into one dataset.

### Sales operations

Keep a CRM data export from OneDrive in sync with Looker Studio for real-time sales dashboards. Append data from multiple regional teams or time periods for unified reporting.

### Product teams

Pull user feedback or bug tracking data from OneDrive, then send it to Perplexity or ChatGPT for automated categorization and summary generation.

## Platform-specific notes

* **Personal OneDrive and OneDrive for Business work the same way** — Just sign in with your Microsoft account and pick your file
* **Shared files are supported** — If someone has shared an Excel file with you, it will appear in the file picker
* **Sheet names matter** — If you rename a sheet after setting up your data flow, you'll need to update the sheet name in the configuration
* **Large files may take longer** — Excel files over 10 MB might take extra time to process
* **Headers are required** — Your Excel sheets should have header rows so Coupler.io knows what each column represents

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.coupler.io/sources/category/files-and-tables/onedrive/data-overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
