What is an IQY file?
An .IQY file is an Internet Query file created by Microsoft. It is a plain text file that contains a URL and connection parameters. Microsoft Excel uses this file to download dynamic data from the internet directly into a spreadsheet.
How to open IQY files?
Users normally open .IQY files using Microsoft Excel. Because the file only stores plain text, you can also open it with a simple text editor. You can use tools like Notepad++, Visual Studio Code, or Apple TextEdit to inspect the target URL and parameters safely.
Security and Best Practices
Since .IQY files instruct the computer to download external data, they carry security risks. Do not open unknown .IQY files in Microsoft Excel, as malicious files can download malware. Always inspect the text content first to verify the source URL before you allow your spreadsheet software to connect to the internet.
Conversion
If you need the actual data instead of the query link, you must run the query in Microsoft Excel and save the resulting data as a .XLSX or .CSV file. You can also explore format conversion options at convert.guru to convert your other files into sensible target formats.
