WEBSERVICE Function

Excel 2013+

Summary

The WEBSERVICE function retrieves data from web services on the Internet or Intranet by making HTTP GET requests directly within Excel formulas. This powerful capability enables dynamic data fetching without leaving your spreadsheet.

WEBSERVICE(url)

Parameters

Parameter	Type	Required	Description
url	`String`	Yes	Required. The URL of the web service endpoint, including any query parameters

Using the WEBSERVICE Function

WEBSERVICE transforms Excel into a dynamic data platform by pulling real-time information from web APIs, RSS feeds, weather services, financial data providers, and custom endpoints. Combine with FILTERXML for XML/JSON parsing or ENCODEURL for proper URL formatting.

Common WEBSERVICE Examples

Basic Weather Data Fetch

=WEBSERVICE("https://api.openweathermap.org/data/2.5/weather?q=London&appid=YOUR_API_KEY")

Retrieves current weather XML data for London from OpenWeatherMap API.

Currency Exchange Rate

=WEBSERVICE("https://api.exchangerate-api.com/v4/latest/USD")

Fetches latest USD exchange rates in JSON format.

With ENCODEURL for Safety

=WEBSERVICE(ENCODEURL("https://api.example.com/search?q="&A1))

Safely encodes search query from cell A1 before making API call.
