The Scenario
You are a developer. Your Resend account has 12 custom contact properties — fields like plan_tier, signup_source, trial_end_date — that drive personalization in your email templates.
The frontend team is building the new signup form and they need the property schema: key names, data types, and fallback values. Instead of going back and forth in Slack, you want to drop a Google Sheet in the shared folder with all 12 properties listed cleanly.
The bad version:
- You open the Resend dashboard, navigate to Contacts, then to Properties
- You screenshot the list and paste it into Slack
- The frontend dev asks for the fallback values, which are not visible in the screenshot
- You go back in, click through each property individually
- It takes forty minutes to produce a table that should have taken four.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that reads the Resend API and writes the property schema into the sheet for you.
Open the SheetXAI sidebar and type:
List all Resend contact properties and write each property's key, type, and fallback value into columns A, B, and C of the ContactProperties sheet. Use row 1 as a header row.
SheetXAI calls the Resend contact properties endpoint, pulls all 12 properties, and writes one row per property. Key in A, type in B, fallback in C.
What You Get
A populated ContactProperties sheet ready to share:
- Column A — property key (e.g.,
plan_tier,signup_source) - Column B — data type (e.g., string, number, boolean)
- Column C — fallback value
- Row 1 — headers
The frontend team has the full schema in one place, including fallbacks. No back-and-forth in Slack, no dashboard clicking.
From there you can add a "used in templates" column, a "owner" column, or a "last modified" column right in the sheet for your own documentation.
What If the Data Is Not Quite Ready
Property schema documentation gets more useful when it includes context. SheetXAI can enrich and extend it in the same prompt.
When you want to bulk-create new properties from the sheet instead of exporting
The frontend team has already drafted the new properties in column A of a NewProperties tab and you need to create them in Resend.
Read the NewProperties tab in this sheet (A=property key, B=data type, C=fallback value) and create each one as a Resend contact property. Write the new property ID in column D for each row.
When you need to flag which properties have no fallback value
Properties without a fallback can cause blank fields in emails. You want to identify them.
List all Resend contact properties and write key, type, and fallback into columns A, B, and C of ContactProperties. Then add "NO FALLBACK" in column D for any row where column C is blank.
When you want to cross-reference which properties are actually used in templates
You suspect some properties are defined but never referenced in any template. You want to find and mark them.
List all Resend contact properties and write their keys into column A of ContactProperties. Also list all Resend templates and their content into a hidden working area. For each property key in column A, check if it appears in any template content and write "in use" or "unused" in column B.
When you need a full schema audit in one shot
You want everything: all properties pulled, fallbacks flagged, and a "create date" column if available, sorted so the ones without fallbacks are at the top.
List all Resend contact properties and write key, type, fallback value, and creation date (if available) into columns A through D of ContactProperties. Add "NO FALLBACK" in column E for rows with blank fallbacks. Sort so NO FALLBACK rows appear first.
The pattern: pulling the schema and annotating it happen in one prompt. The frontend team gets a complete reference without anyone digging through the Resend dashboard.
