Automatic Detection

Auto-Clean Your Data

Import your data and we handle the rest. Our engine detects 25+ data types, normalizes inconsistent formats, removes duplicates, and flags invalid rows — no manual work required.

Input
price: "29.99 USD"
phone: "(555) 123-4567"
url: "EXAMPLE.COM/widget/"
Output
price: 29.99 (USD)
phone: +15551234567 (E.164)
url: https://example.com/widget

25+ Data Types Detected

Prices, phone numbers, emails, URLs, dates, currencies, GTINs, ISBNs, SKUs, and more — all detected automatically.

Format Normalization

Inconsistent formats are standardized. Prices become numbers, phone numbers become E.164, URLs get normalized with https://.

Duplicate & Invalid Row Detection

Fuzzy matching catches near-duplicates. Invalid rows are flagged with specific reasons so you can fix or discard them.

Schema Generation

JSON-LD Schema Markup

Map your columns to Schema.org properties with a visual interface. We generate valid JSON-LD for Products, Articles, Local Businesses, and 16 more types.

19 Schema.org Types

Product, LocalBusiness, Article, Recipe, FAQ, Event, JobPosting, Course, and more. Each with complete property support.

Visual Column-to-Property Mapping

Drag and drop your columns onto Schema.org properties. See which fields map to name, price, url, description, and more.

Live Preview with Real Data

Works on Any Website or CMS

WordPress, Shopify, Wix, Squarespace, custom HTML — just paste the script tag. No plugins, no configuration, no compatibility issues.

No Developer Required

Copy one line. Paste into your site header. Done. Update your data in the dashboard — the schema on your site updates automatically.

The Process

How It Works

Three steps from messy data to Google rich results

Import01

Import Your Data

CSV, Google Sheets, or Airtable

Upload a CSV file, connect Google Sheets via OAuth, or import directly from Airtable. Your data is automatically cleaned and validated upon import.

Configure02

Map to Schema.org

Visual column-to-property mapping

Pick a schema type (Product, LocalBusiness, Article, etc.), then map your data columns to Schema.org properties. See a live JSON-LD preview with your real data.

Deploy03

Embed & Go

One script tag, every page covered

Copy one line of code and paste it into your site. The script auto-matches each page to your data and injects the right JSON-LD markup. No dev work, no maintenance.
