What is an ATOMSVC File?

How to Open, Edit, & Convert ATOMSVC Files


A file with the ATOMSVC file extension is an Atom Service Document file. It's sometimes called a Data Service Document file or Data Feed ATOM file.

An ATOMSVC file is a regular text file, formatted like an XML file, that defines how a document should reach a data source. This means there isn't any real data in an ATOMSVC file, but instead just text addresses, or references to the real resources.

Note: ATOMSVC files are similar to ATOM files in that they're both XML-based text files that refer to remote data.

However, ATOM files (like .RSS files) are usually used by news and RSS readers as a way to stay updated with news and other content from websites.

How To Open an ATOMSVC File

Microsoft Excel is able to open ATOMSVC files using PowerPivot, but you can't just double-click the file and expect it to open like how most files do.

Instead, with Excel open, go to the INSERT > PivotTable menu and then select the Use an external data source option. Click Choose Connection..., then Browse for More... to locate the ATOMSVC file, and then decide whether to insert the table into a new worksheet or the existing one.

Note: The add-in PowerPivot for Excel must be installed in order to open an ATOMSVC file in MS Excel 2010. Newer versions of Excel have PowerPivot integrated into the program by default.

Since they're just plain text files, an ATOMSVC file can open with any text editor too, like Windows Notepad or Notepad++.

Microsoft SQL Server should also be able to open ATOMSVC files, as might other programs that deal with large sets of data.

If you find that an application on your PC does try to open the ATOMSVC file but it's the wrong application or if you would rather have another installed program open ATOMSVC files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an ATOMSVC File

I don't know of any special tool or converter that can save an ATOMSVC file to another format. However, since they're used to pull information from some other data source, if you open one in Excel so as to import that data, it's possible that you may then be able to save the Excel document to another spreadsheet or text format. Excel can save to formats like CSV and XLSX.

I haven't tried myself to confirm this, but using this method wouldn't really be converting the ATOMSVC file itself into another format, just the data that it pulled down into Excel. However, you can use Notepad++ to convert the ATOMSVC file to another text-based format like HTML or TXT since the ATOMSVC file itself contains only text.

Note: Most file formats that are more widely used, like MP3 and PNG, can be converted using a free file converter. To my knowledge, there just aren't any that support this format.
