One messy sales export goes in, and three things come back: a cleaned table with consistent names, emails and dates, an itemised list of every cell the AI changed, and a data analysis report with totals, averages and breakdowns measured from the file itself. Nothing below is a mockup.

The table you get back. The same file after one pass: the real header row found, casing and dates made consistent, and every row numbered so the report can point at one.

How It Works: Technical Methodology

Google Gemini Integration

DataSort utilizes Google Gemini 2.5 Flash, a state-of-the-art Large Language Model (LLM), to interpret semantic context within your data. This allows for intelligent operations like fuzzy matching for deduplication and context-aware sorting.

Privacy & Processing

We employ a stateless architecture. Files are parsed locally using SheetJS, and only essential data chunks are sent to the AI model. No file data is permanently stored on our servers, ensuring data privacy and security (SOC 2 compliant underlying infrastructure).

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 is free to use and needs no signup to try it. The Free plan handles files up to 500 rows with 5 AI runs every 20 minutes. Mid raises that to 5,000 rows per file and Pro removes the row limit entirely. If you only need more for a single file, a $2.99 Day Pass unlocks everything in Mid for 24 hours with no subscription.
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 DataSort merge Excel files?
Yes. DataSort merges Excel files directly. AI Smart Merge reads every sheet of every file you upload, matches columns whose names differ (Email vs Contact_Email), and combines them into one table. Most merges fail because headers and formats are inconsistent, so DataSort standardizes them as part of the merge rather than making you clean up first.
Is datasort.app related to datasort.in?
No. DataSort (datasort.app) is a free AI-powered tool for cleaning, merging, and converting Excel and CSV files. We are not affiliated with datasort.in, an Indian freelancer work portal. If you are looking for that portal or its worker login, please visit datasort.in. This site, datasort.app, is the spreadsheet-cleaning tool.
Can I edit the data myself after the AI cleans it?
Yes. The results table is a working surface, not a preview. Click the pencil on a cell, double-click it, or select it and press Enter to change a value, and on a phone or tablet just tap the cell. You can rename and resize columns, drag rows into a new order, delete rows, and tick rows to copy, export or delete them in bulk. Every change is marked in a fixed colour so you can see exactly what you touched, and Ctrl+Z (Cmd+Z on a Mac) undoes up to 25 steps.
Do manual edits use up my AI runs or my row limit?
No. Editing happens entirely in your browser and never calls the AI, so nothing you fix by hand counts against your operation limit. The Free plan's 5 runs per 20 minutes apply only to AI cleaning. You can correct as many cells as you like without spending one.
Will I lose my work if I close the tab?
No. Your work is saved automatically in your own browser, and a "Saved sessions" button at the bottom of the page brings it back when you return. Nothing is uploaded to our servers, which is how the zero data retention promise stays true. It also means saved work does not follow you to a different device or browser, and clearing your browser data removes it. Free keeps your most recent session automatically; Mid and Pro can save up to 10 named sessions and switch between them.
