How to Use This Tool — 3 Simple Steps
You don’t need any technical knowledge. Here’s all it takes:
01
Copy your data
Select any table in Excel or Google Sheets and press Ctrl+C. Works with comma-separated (CSV) and tab-separated data too.
02
Paste & Analyze
Click inside the text box above, press Ctrl+V to paste, then click “Analyze My Data”. Charts appear instantly.
03
Export or Download
Download individual charts as PNG images, or export everything — charts + AI insights + data table — as a PowerPoint file in one click.
💡 Pro tip: Make sure your first row contains column headers (like “Month”, “Sales”, “Region”). The tool automatically detects which columns are numbers and which are categories — no setup needed.
What You Get Instantly
After you paste your data and click Analyze, the tool generates four things automatically:
Bar Chart — Comparison
Compares values across categories. Automatically groups and aggregates your data. Supports multiple numeric columns.
Pie Chart — Share of Total
Shows what percentage each category contributes. Labels update automatically with exact percentages.
Line Chart — Trend Over Time
Tracks how your numbers change over time or sequence. Supports date grouping by day, month, or year.
AI Insights — Plain English
Automatically identifies your top performer, profit margin, trend direction, outliers, and category concentration. No prompting needed.
Who Is This Tool For?
This tool is built for people who work with data but don’t want to fight with software. It’s perfect for:
- Business analysts who need quick charts for a meeting or report without opening Excel
- Sales managers who want to visualize monthly or regional performance in seconds
- Students and teachers who need simple charts for assignments or classroom presentations
- Small business owners who track revenue, expenses, or inventory in a spreadsheet
- HR professionals who analyze headcount, attrition, or survey results
- Anyone who has ever copy-pasted data into Google Sheets just to make a quick chart
Why Use This Instead of Excel or Google Sheets?
10x Faster
Excel takes 15–20 steps to make a formatted chart. This tool does it in one click, automatically.
100% Private
Your data is processed entirely in your browser. Nothing is sent to any server. Nobody can see your data.
AI Insights Included
Unlike basic chart tools, this one tells you what the data means — top performers, trends, margins — in plain English.
PPT Export Built In
Export a full presentation with title slide, insights slide, charts, and data table. Ready to share in meetings.
What Data Format Does It Accept?
The tool accepts any of the following formats — no conversion needed:
- Excel copy-paste — just select cells in Excel and paste directly
- Google Sheets copy-paste — works the same way
- CSV format — values separated by commas
- Tab-separated format — values separated by tabs
Your first row must contain column headers. Dates can be in any common format (Jan, 2025-01-01, 01/01/2025). Numeric columns are detected automatically — no manual selection needed.
💡 Sample data format:
Month Region Product Sales Profit
Jan East Apple 5200 1400

Frequently Asked Questions
Is this tool completely free?
Yes, 100% free. No hidden charges, no credit card, no premium plan needed. All features — charts, AI insights, PPT export, image download — are free for everyone.
Do I need to create an account or sign up?
No signup required. Open the page, paste your data, and start analyzing immediately. No email, no password, no registration.
Is my data safe? Does it get stored anywhere?
Your data never leaves your device. The entire tool runs inside your browser using JavaScript. No data is sent to any server, stored in any database, or shared with anyone. You can even use it offline after the page loads.
What is the AI Insights feature?
The AI Insights block automatically analyzes your data and writes plain-English observations — such as which category is the top performer, what the profit margin is, whether the trend is going up or down, and whether any one category is dominating the total. It works without any AI API — the analysis runs entirely in your browser using smart JavaScript logic.
How many rows of data can I analyze?
The tool works best with datasets up to 1,000 rows. Larger datasets may slow down the chart rendering depending on your device. For very large datasets, we recommend summarizing or filtering before pasting.
Can I export my charts as images?
Yes. Each chart has a “Download image” button that saves it as a PNG file. You can use these images in Word documents, emails, presentations, or social media posts.
What does the PPT export include?
The exported PowerPoint file includes: a title slide with your data summary, an AI Insights slide with plain-English observations, individual slides for the bar chart, pie chart, and trend line, and a data table slide showing your first 10 rows. The file is ready to present without any editing.
Does it work on mobile phones?
Yes. The tool is mobile-responsive and works on Android and iPhone browsers. You can paste data from Google Sheets mobile and analyze it directly on your phone.
What if my data has dates? Will the line chart show them correctly?
Yes. The tool automatically detects date columns and sorts them chronologically on the line chart. It also supports date grouping — you can switch between daily (DD-MM-YY), monthly (MM-YY), or yearly (YY) views using the dropdown on the chart.
Can I analyze Google Sheets data?
Absolutely. Open your Google Sheet, select the cells you want to analyze (including the header row), press Ctrl+C to copy, then paste into this tool. It works exactly like pasting from Excel.
