OpenAI launches ChatGPT for Google Sheets as a Google Marketplace add-on

• OpenAI shipped ChatGPT for Google Sheets as a Google Workspace Marketplace add-on, with OpenAI engineer gdb announcing the release in gdb's post and follow-up coverage in TestingCatalog's post.
• The add-on is positioned around natural-language spreadsheet work: users can build, edit, analyze, and update sheets without writing formulas manually, according to Wes Roth's post and AILeaksAndNews' post.
• The clearest workflow shown so far is multi-step sheet automation from within Sheets: the Marketplace demo shows ChatGPT pulling data from Gmail, updating model inputs, refreshing formulas, and reporting profitability changes.

OpenAI's launch looks less like a single-cell formula helper and more like a sidebar agent for workbook tasks. The demo screenshot shows ChatGPT working through a four-step checklist inside Sheets rather than returning one-off text.

The concrete behaviors shown across the launch posts are:

• build full spreadsheets from natural-language prompts, as described in the launch summary
• analyze workbooks across tabs and formulas, per the same post
• update sheets in real time from the sidebar workflow shown in Wes Roth's screenshot
• pull external context into the sheet workflow; the demo has ChatGPT finding the latest Gmail thread, mapping new conversion assumptions into model cells, and then recalculating profitability

The screenshot details matter because they show stateful task execution inside a live workbook: ChatGPT is "Working 52s," tracks "0/4 tasks completed," and lists actions such as "Find latest Gmail thread" and "Map conversion estimates into model input cells" in the Marketplace demo. That makes this closer to an in-app operator for spreadsheet maintenance than a chat box bolted onto Sheets.
