How do I merge Excel files with DataSort?

Merging fails when files have different headers or formats. Upload each file to DataSort first. Our AI will standardize headers (e.g., matching 'First Name' to 'Candidate Name') and clean formatting. Once all files are standardized, you can easily merge them in Excel without errors.

Can I merge CSV files?

Yes. DataSort accepts both Excel (.xlsx) and CSV files. You can clean both types to ensure they have matching columns before combining them.

How does DataSort handle different column names?

DataSort uses AI to identify the 'Master Schema' from your first file and automatically maps columns from other files to it. It can intelligently rename columns (e.g. 'Phone' -> 'Contact Number') and transform data (e.g. splitting names) to match the master format.

Can it merge rows for the same customer or product?

Yes. Our AI performs Entity Resolution. It detects unique identifiers like Email addresses or IDs and merges multiple rows identifying the same entity into a single, comprehensive record, filling in missing data from all files.

How many files can I merge?

You can merge as many files as you like! The first file you select becomes the Master Schema, and all subsequent files are transformed to match it before being combined.

Common Questions about Merging

Why do my Excel merges fail?

Merges usually fail because of inconsistent headers (e.g., "Email" vs "E-mail") or formatting discrepancies. DataSort uses AI Smart Merge to detect these inconsistencies, standardize them to your Master Schema, and even write custom code to split or transform fields so they match perfectly.

Can it merge same-entity rows?

Yes. DataSort detects unique keys (like Email or ID) and performs Entity Resolution. This means if "John Doe" exists in File A and File B, their data is combined into a single row, rather than creating duplicates.

How many files can I upload?

You can upload and merge as many files as you need! The first file serves as the "Master Schema", and our AI automatically aligns all subsequent files to match its structure.

Is this cleaner free?

Yes, DataSort offers a generous Free plan that includes 5 AI runs every 20 minutes for files up to 500 rows. For unlimited runs, larger files, and advanced AI features, we offer Mid and Pro plans.

How It Works

Smart Header Recognition

DataSort's AI understands that "Client Name", "Customer", and "Name" likely refer to the same thing. It unifies these headers to ensure successful merging.
