AI for Retail Data Analysis: 3 Free Tools in 2026
In 2025, Brazilian retail generated over R$300 billion in online sales, according to the Brazilian Association of Electronic Commerce (ABComm). However, 60% of small and medium-sized enterprises still use manual spreadsheets to analyze this data, wasting time and opportunities. In 2026, three free AI-powered tools are changing this scenario: Google Sheets with Gemini, Rows AI, and Airtable. They allow you to create analyses and dashboards using natural language, without complex formulas.
In this guide, you'll see how each one works, what they offer for free, and where it's worth investing time to optimize retail data analysis.
Google Sheets + Gemini: The Spreadsheet That Understands Portuguese
Google Workspace integrated Gemini AI directly into Sheets in 2025, as announced on the official Google Workspace blog (Google, 2025). The result is that you can write "create a formula that sums January sales if the value is greater than 1000" and the AI returns the ready-made formula.
This is not an add-on. It's a replacement for learning formulas.
What Gemini does in Sheets (free):
- Formula generation: Describe what you want in natural language. The AI writes the formula.
- Chart creation: Ask for "bar chart showing sales by month" and it inserts the visual.
- Data analysis: Ask "which month had the highest growth?" and it responds with visual highlights.
- Sorting and filters: "Sort column C from largest to smallest and filter only those with more than 50 units."
Free plan limitation: Gemini in Google Workspace has a monthly prompt limit. For heavy use (more than 100 interactions/day), you need the Business plan ($20/month). But for small businesses and freelancers, the free tier covers it well.
Quick step-by-step:
- Open Google Sheets.
- Click the Gemini icon (star) in the top right corner.
- In the panel that opens, type your command in Portuguese.
- The AI displays the formula or chart. Click "Insert" to apply.
Source: According to McKinsey's "The State of AI in Business" report (2025), 70% of spreadsheet users reported increased productivity when using AI assistants to generate formulas, reducing analysis time by up to 40%.
Rows AI: Create Entire Spreadsheets with a Single Prompt
Rows is a cloud-native spreadsheet platform with built-in AI. The difference from Google Sheets is radical: you don't need an existing spreadsheet. Rows creates the structure from scratch.
How it works:
You type something like "create a monthly expense tracking spreadsheet with categories, values, and a pie chart showing the distribution." In seconds, Rows generates the complete spreadsheet with sample data, formulas, and chart, as documented on the official Rows website (Rows, 2026).
Free Rows AI features:
- Spreadsheet generation by prompt: Creates tables, columns, and synthetic data.
- Python and SQL support: You can write code directly in cells. The AI helps generate this code.
- API integration: Connect data from Stripe, Google Analytics, HubSpot, etc.
- Ready-made templates: Dozens of templates for finance, marketing, HR, and sales.
Where Rows shines: For those who need quick reports without prior structure. It's ideal for startups and marketing professionals who want to visualize campaign data without involving the IT team.
Limitation: The free plan limits the number of rows (1,000) and columns (50) per spreadsheet. For large datasets, the Pro plan ($19/month) is required.
| Feature | Google Sheets + Gemini | Rows AI | Airtable AI |
|---|---|---|---|
| Formula generation | Yes, by prompt | Yes, by prompt | Yes, by prompt |
| Spreadsheet creation from scratch | No (needs structure) | Yes | Yes (with templates) |
| Charts and dashboards | Yes, via command | Yes, automatic | Yes, dynamic |
| Free limit | Prompts/month (100) | 1,000 rows | 1,000 records |
| SQL/Python support | No | Yes | No (low-code only) |
| Integrations | Google Workspace | External APIs | +100 apps |
Airtable AI: Dynamic Dashboards Without Programming
Airtable has always been a middle ground between a spreadsheet and a database. Now, with integrated AI, it becomes a machine for creating interactive dashboards without writing a single line of code.
What AI does in Airtable:
- Interface creation: Describe the dashboard layout ("I want a panel with sales cards, a line chart, and a filtered table") and the AI builds it.
- Report automation: Set up automatic triggers — for example, "send a weekly summary by email with updated data."
- Smart classification: The AI automatically categorizes data. Drop in a lead spreadsheet and it identifies profiles, priorities, and next steps.
- Smart forms: Create data collection forms that feed the dashboard in real-time.
Free plan: 1,000 records per base, 2 GB of attachments, and 2 automations. For professional use, the Team plan ($20/month) unlocks 50,000 records and unlimited automations, according to the Airtable pricing page (Airtable, 2026).
Who it's for: Operations, HR, logistics, and sales teams that need live dashboards — ones that update automatically as new data comes in.
Step-by-step to create a dashboard in Airtable AI:
- Create a base (table) with your data or import a spreadsheet.
- Click "Interfaces" and then "Create with AI."
- Describe what you want to see on the dashboard.
- The AI generates the interface. You can adjust colors, filters, and fields manually.
- Publish the dashboard and share it with your team.
Which One to Choose? The Decision Guide
Each tool solves a different problem. Here's a summary to keep you on track:
Google Sheets + Gemini: For those who already live in the Google ecosystem. If you need complex calculations, formulas, and want to keep using what you know, but supercharged by AI. The advantage is zero cost and familiarity.
Rows AI: For those starting from scratch. If you don't have a spreadsheet and want to generate a complete analysis with a single prompt, Rows is faster. It's also better for those who need API integration or want to write SQL/Python within the spreadsheet.
Airtable AI: For those who want live, collaborative dashboards. If you need multiple people to feed data (via forms) and want to see everything updated in real-time on a visual panel, Airtable wins. It's more of a database than a spreadsheet.

Conclusion: Excel Didn't Die, But It Lost Relevance
In June 2026, keeping Excel as your primary data analysis tool is like insisting on using a paper map when Waze exists. Free AI alternatives already deliver more speed, fewer errors, and zero need for memorizing formulas.
Google Sheets with Gemini is the most natural entry point for those already using Google Workspace. Rows AI is the shortcut for those wanting immediate results without prior structure. And Airtable AI is the choice for collaborative, dynamic dashboards. Choose the one that best fits your business and start transforming your retail data today.
