Modify Single Document
You can edit existing documents in your collection.
When you edit a document in List or Table view, Compass performs a findOneAndUpdate operation and updates only those fields that you have changed.
When you edit a document in JSON view, Compass performs a findOneAndReplace operation and replaces the document.
Limitations
Modifying documents is not permitted in MongoDB Compass Readonly Edition.
Procedure
Select the appropriate tab based on whether you are viewing your documents in List, JSON, or Table view:
To modify a document, hover over the document and click the pencil icon:
After you click the pencil icon, the document enters edit mode. You can now make changes to the fields, values, or data types of values.
Delete Fields
To delete a field from a document, click the icon to the left of the field:
Once selected, the field is marked for removal and appears highlighted in red. Compass asks for confirmation that you want to update the document by removing the field.
Add New Fields
To add a new field in the document after an existing field, hover over the row number in the dialog and click on the plus sign. The row number is not part of the document but is part of the dialog display.
You can also add a new field at the end of the document by pressing the tab key when your text cursor is in the value of the last document field.
Modify an Existing Field
To modify documents, click on existing field names or
values and make changes. In this example, the airline was
changed from 4 to 2. Changed fields appear highlighted in
yellow:

Save Changes

button to commit your changes.
