AI Data Harmonizer
Data Harmonization & Merging
Stop wrestling with VLOOKUP. Upload two disparate datasets, and our AI will intelligently map schemas, identify join keys, and merge them into a single source of truth.
Unlock Intelligent Joins
Data Harmonization allows you to merge complex files without writing a single line of code or SQL. Create a free account to start merging — your signup bonus credits are on us.
AI Schema Mapping
Automatically matches "CustID" to "Customer_Number" using semantic analysis.
Smart Joins
Handles Inner, Left, and Fuzzy joins. Suggests cleaning steps before merging.
Secure Processing
Files are processed in an ephemeral AWS environment and deleted instantly.
Free to start — no credit card required
The AI Data Harmonizer merges two datasets that do not share the same structure. Upload both files and the AI uses semantic schema matching to figure out which columns correspond — even when they are named differently, like "Cust ID" and "customer_number" — proposes the join, and produces a single unified file. It is a VLOOKUP and manual-mapping replacement that handles the hard part for you.
How it works
- 1
Upload two datasets
Sign in and add the two files you want to combine into one.
- 2
AI matches the schemas
Semantic matching aligns equivalent columns across the files, even with different names or order.
- 3
Confirm the join
Review the suggested column mapping and join key, and adjust if needed.
- 4
Download the merged file
Get one harmonized dataset combining both sources, ready to use.
Use cases
Combine systems of record
Join a CRM export with a billing or product export that uses different column names.
Enrich a list
Attach attributes from a reference dataset to a working list without writing lookups.
Consolidate regional files
Unify spreadsheets from different teams or regions whose schemas drifted apart.
Migration mapping
Reconcile old and new system exports during a data migration or platform switch.
Why DatumFuse
Semantic column matching
AI understands that differently-named columns mean the same thing — no manual mapping table.
No formulas
Replaces fragile VLOOKUP and INDEX/MATCH chains with a guided, reviewable join.
You confirm the keys
The AI proposes the join, but you approve the mapping and join key before it runs.
Built for mismatched data
Designed specifically for sources that were never meant to line up cleanly.
