Watch DataSort sort and clean a messy file

Unedited screen recordings of the real app, not an animation.
Every clip below is one continuous take on datasort.app, cleaning, normalizing and editing a messy export. Nothing is cut. Only the AI's own waiting time is sped up. Pick a clip to watch it here on the page.

Ask the assistant to change the table. Type the change you want in plain English, or take one of the suggestions it offers. It writes the transformation, applies it to the sheet, and tells you what it could not do rather than guessing.

Sort Excel and CSV columns

Sort any column alphabetically or numerically, or group by categories. DataSort reads your headers and values and applies sorting in a consistent way across the entire file.

AI Data Assistant

Chat with your data using natural language. Ask questions, request transformations, and get instant insights without writing complex formulas.

Clean, deduplicate, then sort

Instead of sorting messy data, let AI clean it first. DataSort fixes obvious formatting issues, removes duplicate rows, and then sorts the cleaned dataset so you do not hide mistakes with sorting.

Geospatial Enrichment

Automatically add location data to your files. DataSort can enrich your dataset with Latitude, Longitude, City, and Country based on existing address columns.

Pattern Extraction

Extract emails, phone numbers, or custom patterns from messy text fields. Turn unstructured text into clean, structured columns instantly using AI.

Smart Deduplication

Identify and remove duplicate rows with intelligent matching. You can undo any changes if the result isn't exactly what you expected.

Sort CSV Files Online

Easily upload and sort massive CSV datasets without worrying about Excel row limits or formatting corruption. Our in-browser engine handles comma-separated values instantly, preserving your raw data structure.

Multi-Level & Custom Sorting

Go beyond A-Z. Sort by multiple columns simultaneously (e.g., sort by Department, then by Employee Name). Apply custom AI rules to sort by priority, status, or mismatched date formats effortlessly.

100% Private Browser Processing

When you sort your Excel data online with DataSort, your sensitive files are processed securely. Basic sorting and filtering happen locally in your browser, meaning your raw spreadsheets are never exposed.

Common Questions

How do I sort Excel and CSV data online?
Upload your Excel (.xlsx, .xls) or CSV file to DataSort. Click any column header to toggle ascending or descending sort order with natural numeric and date sorting. You can also filter columns by condition or ask the AI Assistant in plain English to reorganize complex datasets. The entire operation runs privately in your browser with zero formula errors, no software to install, and no signup required.
What is DataSort?
DataSort is an intelligent, browser-based AI Excel cleaner, normalizer, and sheet merger 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.
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 100% free to use with all core features included and no signup or credit card required. 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.
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.
Can I sort the table myself without re-running the AI?
Yes. Click any column header to sort by that column, and click again to reverse it. Sorting happens in your browser and costs nothing, so it does not use an AI run on any plan. Sorting one column at a time is supported; there is no multi-column sort.

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).
