AI-Powered Mapping

AI-Generated Field Mappings

Upload your source schemas and select a destination. AI analyzes field names, data types, sample values, and semantic meaning to generate a complete mapping in a single pass. When fields need format conversion — dates, numbers, string formatting — AI generates the transformation logic automatically and shows you the output on your data.

  • Confidence scores with reasoning for every mapping decision
  • Automatic format conversion: dates, numbers, string parsing, conditional logic
  • Multi-source schemas mapped to one destination simultaneously
  • Sample output preview on your data before accepting
AI Mapping Result
source.customer_name
destination.full_name 98%
Direct mapping. Field names are semantic equivalents.
source.price, source.qty
destination.total_amount 91%
Calculated field. Multiplies unit price by quantity.
source.created_at
destination.order_date 95%
Date format conversion. ISO 8601 to YYYY-MM-DD.
Transformation — validated
// AI-generated, tested against source data
const first = $0?.split(' ')[0] ?? '';
const last = $0?.split(' ').slice(1).join(' ') ?? '';
return (last + ', ' + first).trim();
Sample output:
"John Smith""Smith, John"

Transformation Expressions

When your source and destination formats differ, AI generates the transformation logic automatically. Every expression is validated against your source data before you see it — you review sample output, not code. If the first attempt produces errors, AI self-corrects using the error feedback until the expression passes.

  • Date parsing, string formatting, number conversion, conditional logic
  • Every expression validated in a sandboxed environment before production
  • Preview output on your data before accepting

Multi-Source Join Discovery

Most real-world integrations involve more than one data source. Orders live in one system, customers in another, product catalogs in a third. Figuring out how those sources relate — which fields match, what kind of join to use, how to handle case mismatches or format differences — is traditionally the most time-consuming part of the project. datathere handles it automatically.

When your mapping includes multiple sources, AI examines field names, data types, and sample values across all of them to identify relationships. It recommends join types, generates match conditions, and rates each relationship with cited evidence so you can see why it was suggested.

  • Automatic relationship detection across all connected sources
  • Confidence rating (strong, moderate, weak) with specific evidence
  • Handles case-insensitive matching, date format differences, composite keys
  • Join type recommendations (inner, left, right) with reasoning
  • Human-readable explanations alongside technical conditions
Discovered Relationship STRONG
Source
orders.customer_id
Lookup
customers.id
Type
LEFT JOIN — all orders preserved, customer data enriched where available
Evidence: 98.7% of order customer_id values found in customers.id. Integer type match.
Discovered Relationship MODERATE
Source
orders.sku
Lookup
products.product_code
Type
LEFT JOIN — case-insensitive match recommended (mixed casing detected)
Evidence: 89.2% match rate after case normalization. String type, similar value patterns.
Grain Analysis
Detected

Source grain is order line items (1 row per product per order). Destination expects order totals (1 row per order).

Recommended Grouping
Group by order_id
total_amount SUM(line_total)
item_count COUNT(sku)
Preview: 1,247 source rows → 312 aggregated rows

Aggregation and Grain Analysis

When your source data is more granular than what the destination expects — order line items vs. order totals, daily transactions vs. monthly summaries — AI detects the mismatch and recommends how to aggregate. It suggests grouping fields, aggregation functions, and calculated fields. You preview the aggregated output on a sample of your data before committing.

  • Automatic grain mismatch detection
  • SUM, AVG, COUNT, MIN, MAX, and array aggregation
  • Multi-level grouping with calculated fields
  • Nested array flattening for complex source structures

Plain English Editing

You should never have to read or write code to manage a data mapping. When something needs to change — a field mapping, a transformation, an aggregation rule, a join condition — describe what's wrong in plain language. "This should be uppercase." "Split first and last name." "Only include orders from the last 90 days." AI updates the underlying logic, tests the change against your data, and shows you the result. Accept or reject with one click.

  • Edit field mappings, transformations, aggregations, and joins
  • AI generates the update and tests it against your data
  • See which records pass and fail before accepting
You say
"Convert to last name, first name format"
Transformation updated. 50/50 samples pass.
You say
"Must be a valid email address"
Validation rule generated. 47/50 samples pass.
You say
"Match on customer email, ignore case differences"
Join condition updated. Case-insensitive match applied.
destination.internal_score
No source field contains numeric values in the required range. The closest candidate (source.rating) contains text values that cannot be reliably converted.
destination.approved_by
No source field represents an approver identity. This field likely requires manual input or integration with an external approval system.

Unmapped Field Transparency

AI accounts for 100% of your destination fields. When a field can't be mapped, you get a specific reason: what data was available, what was attempted, and why it wasn't sufficient. This eliminates the ambiguity of staring at an empty mapping and wondering whether the system missed something or the data isn't there.

  • Specific technical reasoning for every unmapped field
  • Closest candidate fields identified with explanation
  • Full destination field coverage — every field accounted for

Certification Before Production

Before a mapping runs in production, you certify it. Certification validates every component — field mappings, join conditions, transformation expressions — and locks the configuration. The certified version is what runs. Any modification after certification requires unlocking with a written justification that's recorded in the audit trail. You know what configuration is active in production and who last changed it.

  • All mapping components validated before certification
  • Locked configuration — the certified version is what runs
  • Unlock requires written justification in the audit trail
  • Version tracking — see who certified, when, and what changed
