The Scenario
You are the CX director and the quarterly business review is in three days. Your VP wants a single slide: total calls, average duration, and total spend, broken down by assistant, for Q1. The data is in Vapi. Your Excel workbook is blank.
You know Vapi has an analytics query API. You do not know how to call it, what the request body looks like, or how to parse the grouped response into a format Excel can read.
The bad version:
- Find the Vapi analytics API docs, read through the query schema, figure out which fields support groupBy
- Write or find a script that constructs the right request body, authenticates, handles pagination if the result set is large
- Parse the JSON response, extract the right fields, format them into rows, paste into your workbook
- Realize the cost field came back in fractional cents, not dollars, and redo the column
Three days is not a long runway when you also have a team to manage and a deck to build.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It knows Vapi's analytics query structure and writes the aggregated results directly into your worksheet — no script, no JSON parsing.
Query Vapi for total calls and average cost per assistant over the last 90 days and populate my Excel sheet with one row per assistant
What You Get
- One row per assistant, with the assistant ID, total call count, average cost, and any other requested metrics in separate columns
- Cost arrives formatted as a decimal dollar amount — ready for your slide
- Headers land in row 1 automatically — ready to hand to your VP without reformatting
What If the Data Is Not Quite Ready
You want the results sorted by total cost, highest first
Query Vapi for total calls and average cost per assistant over the last 90 days — sort the results by total cost descending before writing to my Excel sheet
You only want assistants that handled more than 50 calls
Query Vapi for total calls and average cost per assistant over the last 90 days — write only assistants with total call count above 50 into my Excel sheet
You need the same breakdown for two quarters for comparison
Run two Vapi analytics queries — one for Q4 2025 and one for Q1 2026, both grouped by assistantId with call count, average duration, and total cost — write Q4 results starting at row 2 and Q1 results starting at row 15, with a header row for each set
Pull, clean, summarize, and flag in one shot
Query Vapi for Q1 2026 grouped by assistantId — exclude any assistant with fewer than 10 calls — format total cost as dollars with two decimals, format average duration as minutes rounded to one decimal — write results into my Excel sheet and add a column marking assistants where average cost per call exceeds $0.50
Combining the filter, formatting, and flag in a single prompt means the workbook is ready to present without any follow-up cleanup.
