What the result means
This preflight validator checks your Google Ads Editor bulk upload CSV or TSV locally against official Google schema definitions. It identifies unrecognized or misspelled column headers (such as 'Campaign Name' instead of 'Campaign'), detects missing parent relationships (e.g. ad groups or keywords without a specified campaign), validates match types and keyword punctuation conflicts, and checks Responsive Search Ad copy length limits (headlines <= 30 chars, descriptions <= 90 chars). Download the issues audit report or export a cleaned CSV with corrected canonical column headers.

Questions
Why does Google Ads Editor show 'Ambiguous row type' during CSV import?
Google Ads Editor throws 'Ambiguous row type' when a row contains values but lacks the identifying columns needed to determine what entity is being created or modified (e.g., missing 'Keyword', 'Headline 1', or 'Ad Group' settings).
Can I use AI (ChatGPT or Claude) generated bulk spreadsheets?
Yes, but LLMs frequently hallucinate column headers (like using 'Match Type' instead of 'Criterion Type' or 'Campaign Name' instead of 'Campaign'). This tool flags those header aliases and lets you download a remapped CSV with Google's official column names.
What are the character limits for Responsive Search Ads in bulk uploads?
Headlines are limited to 30 characters each (minimum 3, maximum 15). Descriptions are limited to 90 characters each (minimum 2, maximum 4). Path 1 and Path 2 display paths are limited to 15 characters each.
Does passing this validation guarantee import approval in Google Ads?
No. This tool validates syntax, schema headers, entity hierarchy, and length constraints. Google Ads Editor performs additional account-level checks, including trademark policies, editorial rules, and billing status.
Are my campaign names and keywords uploaded to any server?
No. All CSV parsing and schema validation happens 100% locally in your web browser using Web Workers. No campaign or keyword data is ever transmitted across the network.
