About .rqy Files
RQY files are plain text files that store query instructions for Microsoft Excel's OLE DB system.
They contain commands, connection strings, and SQL queries needed to fetch data from external databases.
These files use the MIME type text/plain and are mainly used to automate data import into Excel.
- Main use: To run external database queries from within Excel.
- Format: Simple text containing OLE DB query details.
- Software: Microsoft Excel primarily processes these, but any text editor can view them.
- Key fact: They enable integration of external data sources with Excel spreadsheets.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .rqy file used for?
An RQY file is a plain text file containing OLE DB query specifications used by Microsoft Excel. It stores connection strings and SQL commands that tell Excel how to retrieve data from an external database. You can view the underlying text structure because it uses the standard text/plain MIME type.
How do I open an RQY file?
To execute the query and import data, simply double-click the file to open it in Microsoft Excel. If you want to view or modify the code inside, right-click the file and select "Open with" to choose a text editor like Notepad or Notepad++.
Are RQY files safe to open?
You should exercise caution. Because RQY files execute commands against databases and can trigger external connections, they can theoretically be used maliciously to exfiltrate data. Only open .rqy files from trusted sources, and be aware that Microsoft has tightened security around OLE DB features to prevent exploits.
How do I create or edit an RQY file?
Since these are text-based, you can create one using any text editor. The file typically starts with the [OLE DB Query] header, followed by lines for the connection string (starting with Provider=) and the SQL command. Save the file with the .rqy extension to ensure Excel recognizes it.
Why does Excel block my RQY file from running?
Modern versions of Excel (such as Excel 365) often block external data connections by default for security reasons. You may need to adjust your Trust Center settings to "Enable external data connections" or unblock the specific file in its Windows Properties menu.
Can I convert an RQY file to an Excel spreadsheet (.xlsx)?
You cannot convert the script file directly, but you can save the results of the script. Open the .rqy file in Excel to run the query and fetch the data, then use File > Save As to save the resulting dataset as a standard .xlsx or .csv file.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
