Frequently asked questions
Will the merged file include the GA4 summary rows at the top?+
If the export includes a multi-line header block, run it through the CSV Cleaner first to strip those rows before merging.
Can I merge exports from different GA4 properties?+
Yes, as long as the column structure is comparable. Columns are matched by header name, so differing properties can be combined cleanly.
Is analytics data uploaded?+
