Find all columns internal names in SharePoint list

es! You absolutely can get all internal names of columns in a SharePoint list without checking them one by one manually. Here are the two most efficient ways, depending on your level of access and tools available:

Option 1: Use PowerShell 
If you have access to PowerShell and PnP module installed:

# Connect to the site
Connect-PnPOnline -Url "https://yourtenant.sharepoint.com/sites/yoursite" -UseWebLogin

# Get fields from your list
Get-PnPField -List "Your List Name" | Select InternalName, Title, TypeDisplayName

This will give you a clean table of:

• InternalName (what you want)
• Title (the display name)
• TypeDisplayName (type of column)

Option 2: Use SharePoint REST API in Browser
In your browser, paste the following URL (replace accordingly):

https://yourtenant.sharepoint.com/sites/yoursite/_api/web/lists/getbytitle('Your List Name')/fields?$select=Title,InternalName,TypeAsString

Change "yourtenant", "yoursite" and "Your List Name"

You’ll get a full JSON response with all the info.
