The Scenario
The data governance initiative has been running for two months. A data governance lead inherited ownership of PostHog's event taxonomy with 120 event definitions — many with blank descriptions, undefined owners, and no verification status. The finance team wants an offline review: everyone on the product and engineering team gets a spreadsheet, marks which events they own, and writes descriptions for the ones in their domain. That process requires the full taxonomy exported to a sheet first. PostHog has no one-click export for event definitions.
The bad version:
- Open PostHog's data management section, navigate to event definitions, scroll through the paginated list, click each event to view its description and owner, manually copy those fields into a spreadsheet row
- Get through 40 events and realize that PostHog's UI shows the event volume as "30-day count" but doesn't clarify what timezone is used, so you note "unknown" in the volume column for every row
- Share the 120-row spreadsheet after three hours of copying, receive updates from the team, and then realize you have no way to write those updated descriptions back into PostHog without going through each event in the UI again
An offline taxonomy review only works if the export is complete and the writeback is tractable.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet. It calls PostHog's event definitions endpoint — handling all pagination — and writes the full taxonomy into your sheet in one operation. When the team sends updates back, it can write those too.
Fetch all event definitions in the PostHog project and write event name, description, owner name, is_action status, and volume 30-day count into columns A through E.
What You Get
- All 120 event definitions appear as rows — name, description, owner, is_action status, and 30-day volume
- No pagination cutoff — every event, not just the first page the UI loads
- The sheet is immediately ready for team annotation and offline review
What If the Data Is Not Quite Ready
You want to write updated descriptions back into PostHog
For each row in the 'Event Definitions Update' sheet with a description in column B, update the PostHog event definition named in column A with the new description. Write 'Done' in column C after each successful update, and the error message for any that fail.
You want to flag events with no owner and no description
Fetch all PostHog event definitions and write name, description, and owner into columns A through C. In column D, write "Needs owner" for events with no owner, "Needs description" for events with no description, and "Needs both" for events missing both.
You want property definitions too
Fetch all PostHog property definitions and write property name, type, description, and associated event into columns A through D of the 'Property Taxonomy' sheet. Flag any property with no description in column E.
Full governance audit with priority triage
Fetch all PostHog event definitions. Write name, description, owner, verification status, and 30-day volume into columns A through E. In column F, write a triage priority: "High" for events with volume above 1000 and no description; "Medium" for events with volume 100-1000 and no description; "Low" for everything else missing a description. Sort by priority then by volume descending, and write the sorted result to the 'Taxonomy Triage' sheet.
Export, flag, and prioritize — one prompt.
