What is an OPML File?
An OPML (Outline Processor Markup Language) file is a standard XML-based format that is used to organize and share outlines of information. It was originally developed for the purpose of exchanging outline information between different applications, such as outliners, RSS readers, and blogging platforms.
At its core, an OPML file is a structured list of items, often referred to as an outline. Each item in the outline can have various attributes associated with it, such as a title, URL, and notes. The hierarchical structure of the outline allows for categorization and nesting of items, making it a flexible and versatile format for organizing information.
OPML files are commonly used in a variety of scenarios. For example, they can be used to store and share a collection of RSS feeds, allowing users to easily import and export their subscriptions between different feed readers. They can also be used to create and manage a list of bookmarks or favorites, providing a convenient way to organize and access websites of interest.
An OPML file is typically saved with a .opml file extension, and its contents can be viewed and edited using various software and tools. It is important to note that an OPML file is not intended to contain the actual content of the items in the outline, but rather serves as a structure or guide to access that content.
Now that you have an understanding of what an OPML file is, let’s explore how to open, edit, and convert these files to suit your needs. Whether you want to access the information within an OPML file, make changes to the existing outline, or convert it to a different format, we will guide you through the process step by step.
How to Open an OPML File
Opening an OPML file is a straightforward process that can be done using various methods. Here, we will explore three different options to help you access the contents of an OPML file.
Option 1: Using a Text Editor
If you are comfortable working with plain text, you can open an OPML file using any text editor, such as Notepad (Windows) or TextEdit (Mac). Simply right-click on the OPML file and choose “Open With” to select the desired text editor. The contents of the OPML file will be displayed, allowing you to view and analyze the outline structure.
Option 2: Using an OPML Reader
To have a more user-friendly experience, you can use an OPML reader tool. There are several free and paid OPML reader applications available that provide a dedicated environment for viewing and managing OPML files. These tools often offer additional features such as search functionality, sorting options, and the ability to collapse or expand outline items for easy navigation.
Option 3: Using a Web Browser
If you prefer a quick and convenient option without the need to install any software, you can open an OPML file directly in a web browser. Simply double-click the OPML file, or right-click and choose to open it with your preferred browser. The browser will render the OPML file as a structured outline, allowing you to explore its contents and navigate through the hierarchy.
By using one of these options, you can easily open an OPML file and access the information it contains. Now that you know how to open an OPML file, let’s move on to learning how to edit and make changes to the outline in the next section.

Use the file browser to locate and select the desired OPML file, then click “Open” to access its contents within the OPML reader interface.
Using a Web Browser
If you prefer a convenient and accessible option, you can open an OPML file directly in a web browser. Simply double-click the OPML file, or right-click on it and choose to open it with your preferred browser. The browser will render the OPML file as a structured outline, allowing you to explore its contents and navigate through the hierarchy.
Regardless of the method you choose, opening the OPML file is the first essential step before editing. It grants you access to the outline’s structure, allowing you to make changes and modifications accordingly. Take note of the specific software or tool you decide to use, as the subsequent steps may vary depending on the program’s features and functionality.
With the OPML file opened, you are now ready to proceed to the next steps and begin editing the outline. Whether you need to add or remove items, rearrange the hierarchy, or modify attribute details, the ability to open the OPML file sets the stage for a successful editing process.
Step 2: Make Changes to the Outline
Once you have opened the OPML (Outline Processor Markup Language) file, you can start making changes to the outline structure and content. This step allows you to add, remove, or modify items within the outline according to your specific needs. Here’s a breakdown of how you can make changes to the outline:
Add Items:
To add items to the outline, identify the appropriate location within the hierarchy where the new item should be inserted. Determine whether the item should be a child or sibling of an existing item. Then, create a new XML element for the item within the OPML file, ensuring that it adheres to the correct syntax and formatting guidelines. Include attributes such as title, URL, and notes as needed for the new item.
Remove Items:
If you wish to remove items from the outline, locate the undesired item within the OPML file. Remove the corresponding XML element associated with the item, ensuring that you delete both the opening and closing tags. Double-check to confirm that no other items are unintentionally affected by the removal.
Modify Items:
To modify existing items, find the specific item within the OPML file that requires changes. Update the attributes of the XML element associated with the item, such as the title, URL, or notes. Ensure that you maintain the correct structure and syntax of the XML code to avoid any formatting errors.
When making changes to the outline, it’s important to consider the hierarchy and relationships between items. Check if any modifications affect the overall structure of the outline, ensuring that child and parent relationships remain intact. Take care not to introduce any inconsistencies or errors that may impact the functionality of the outline or any tools that rely on it.
You can repeat these add, remove, and modify actions for multiple items within the outline until you achieve the desired changes. Pay attention to the specific requirements or guidelines of the OPML file, as some applications or tools may have additional proprietary attributes or formatting requirements.
With the necessary changes made to the outline, proceed to the next step to save your edited OPML file and preserve your modifications.
Step 3: Save the Edited OPML File
After making the desired changes to the OPML (Outline Processor Markup Language) file, it is crucial to save your edits to preserve your modifications. Saving the edited OPML file ensures that the changes you made to the outline structure and content are stored for future use. Here’s what you need to do:

Alternatively, you can use the keyboard shortcut Ctrl + S (Windows) or Command + S (Mac) to save the file. The text editor will update the existing OPML file with your modifications.
Using an OPML Reader:
If you used an OPML reader application to edit the file, look for a save or export option within the program. This option may be available in the File menu or a dedicated toolbar icon. Click on the save or export option, and the OPML reader will generate and save the edited OPML file with your changes. Specify the desired destination folder and provide a new filename if needed.
Using a Web Browser:
When editing an OPML file in a web browser, saving the edited file is slightly different. Instead of directly saving the changes to the original file, you need to save a copy of the modified OPML file. Right-click on the browser window displaying the OPML file and choose “Save As” or “Save Page As” from the context menu. Select a destination folder, provide a filename, and ensure that the file is saved with the .opml extension.
Ensure that you save the edited OPML file in a location that is easy to find and access. It is recommended to create a backup of the original file before making any changes to prevent data loss or unintended modifications. This allows you to revert to the original file if needed.
By saving the edited OPML file, you successfully store your modifications and ensure that the changes you made to the outline are preserved for future use. With the file saved, you can now proceed to verify the updated outline and confirm that your changes have been successfully applied.
