Files are processed in-memory. We do not persist your uploaded files on our servers. The data is sent securely to Google's Gemini API for processing and returned directly to your browser.

Can DataSort merge multiple files with different headers?

Yes! DataSort's AI Smart Merge can identify a 'Master Schema' from your first file and automatically map and transform columns from all other files to match it. It handles renaming (e.g., 'EmailAddress' to 'Email') and even splits fields (e.g., splitting 'Name' into 'First Name' and 'Last Name') to ensure a perfect merge.

How does it handle duplicate rows during a merge?

DataSort performs intelligent Entity Resolution. If it detects a common unique identifier (like an Email or Customer ID), it can merge separate rows into a single, consolidated record, ensuring you don't get duplicate entries for the same person or product.

Common Questions

What is DataSort?

DataSort is an intelligent, browser-based AI data cleaner and sorter designed for Excel (.xlsx) and CSV files. Unlike traditional spreadsheet tools, DataSort uses a Large Language Model (LLM) to automatically detect headers, remove duplicates based on context, unify formatting (dates, phone numbers), and enrich data with geospatial information—all without requiring complex formulas or macros.

Can it merge files with different headers?

Yes! Our AI Smart Merge feature can take multiple files with different schemas (e.g., "Email" vs "Contact_Email") and automatically map them to a single Master Schema. It even writes custom code to transform and split fields (like separating "Name" into "First Name" and "Last Name") for a seamless merge.

Does it merge duplicate rows?

Absolutely. DataSort performs Entity Resolution. If it finds the same person or product across multiple files (based on Email, ID, etc.), it merges their data into a single, complete row instead of creating duplicates.

Is my data secure?

Absolutely. As a proud member of the Google for Startups Cloud Program, DataSort's infrastructure is built on enterprise-grade security. Files are processed securely in-memory, and we do not permanently store your uploaded spreadsheets on our servers.

Is DataSort 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.

Do I need Excel installed?

No. DataSort runs entirely in your browser. You only need the Excel or CSV file and an internet connection to sort and clean your data.

Can I use this to help merge Excel files?

Yes! Merging excel files often fails because of inconsistent headers or data formats. DataSort is the perfect pre-merge tool. Use it to standardise your headers and clean your data first, so when you do merge your files (using Excel or other tools), everything matches perfectly.
