Drop in two downloads from Google Ads: your Change history and a campaign report segmented by Day. Every change lines up with the same number of days on each side, and changes dated close together are flagged.
Before and after figures are not proof of cause. Seasonality, auction competition, tracking changes and other edits can all move these numbers. This tool lines up dates; it does not say what any change did.
Your files are read inside your browser. Nothing is uploaded.
Download both files, drop them in, and read each change with the days around it. Columns are matched by name on upload, and you can pick a different column if Google renames one.
The change day sits in neither window. When your data runs out on one side, both sides shrink to the same number of days, and the page says so.
CTR, CPC, conversion rate and cost per conversion come from each window's summed counts. A dash means there is nothing to divide by.
Two changes overlap when they share a campaign, or one is account-level, and their change days are at most the window apart.
All dates are read exactly as written in your files, in your account's time zone. A change at 11:59 PM and one at 12:00 AM stay on their own days.
Built by Mulkern AI Systems. A date-alignment tool for your own account data, nothing more.
Google's change history does not list every change. Google says some account-level settings changes may be missing, so a change that is not in your file cannot be flagged.
Days with no activity have no row in Google's report, so the page counts them as zero and tells you how many there were.
Pay once, keep it. Runs offline once installed, on desktop or phone. No account, no sign-in, no upload.
