The Scenario
A platform engineering team keeps a release log in Google Sheets. Every production deploy gets a row: version string, release date, deployer name. For the last three months, nobody registered those releases in PostHog's error tracking — so when errors started appearing, PostHog couldn't attribute them to the correct version. Now there are 15 unregistered releases and a new requirement: from this point forward, every deploy triggers a PostHog error tracking registration. The backfill needs to happen first.
The bad version:
- Navigate to PostHog error tracking, click "Create release," paste the version string from row 1 of the sheet, enter the release date, save — then repeat for the next 14 rows
- Reach release 8 and realize PostHog's release date field expects a specific format — the sheet has dates as MM/DD/YYYY and you've been entering them that way, but the saved records show blank dates because PostHog silently rejected the format
- Go back and re-enter all 8 dates in the correct ISO 8601 format, finish the remaining 7, and then discover that two version strings had a leading space from the Google Sheets export that PostHog accepted but that won't match what the error tracking SDK reports
Fifteen rows, manually entered, with a format gotcha hiding in every other field.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet. It reads your release log and calls PostHog's error tracking release create endpoint for each row — handling date format conversion — and writes returned release UUIDs back into the sheet.
Create a PostHog error tracking release for each row in the 'Releases' sheet — version string in column A, release date in column B — and write each returned release UUID into column C.
What You Get
- PostHog creates one release record per row using version and date from the sheet
- Date values are converted to ISO 8601 before the request is sent
- Column C receives the returned release UUID for each row — your confirmation that registration succeeded
What If the Data Is Not Quite Ready
Version strings have leading or trailing whitespace
Trim all whitespace from column A before creating PostHog error tracking releases. For each row, create a release with the trimmed version string from column A and the date from column B. Write returned UUIDs into column C.
You also want to export error fingerprints for triage
Fetch all PostHog error tracking fingerprints for this project and write error title, occurrence count, first-seen date, and status into columns A through D of the 'Error Triage' sheet. Sort by occurrence count descending.
You want to flag releases with date parsing failures before sending
Before creating any PostHog error tracking releases, validate that all values in column B are parseable as dates. Write "Invalid date format" in column C for rows that fail, and skip those rows. For all other rows, create the release and write the returned UUID into column C.
Backfill all releases, then export errors attributed to each version
Create PostHog error tracking releases for all rows in the 'Releases' sheet — version from column A, date from column B. Write UUIDs into column C. Then fetch the current list of PostHog error fingerprints and write error title, version attributed, and occurrence count into columns A through C of a new 'Error Attribution' sheet.
Register and then immediately audit what's been attributed — one prompt covers both.
