Columnly AI is an intelligent data analyst built directly into Google Sheets. Ask in plain English — Columnly cleans your data, generates formulas, restructures tables, formats your sheet, and delivers analyst-grade insights without you writing a single line of code. Every figure it reports traces back to the cell it came from.

What Columnly AI does:

- Data Cleaning — Fix mixed formats, remove duplicates, normalize dates, fill missing values, and standardize casing across any column. Cleaning updates your sheet directly, and every change can be undone from the sidebar.
- Formula Generation — Get formulas like SUMIF, VLOOKUP, and ARRAYFORMULA written into your sheet and explained in plain English.
- Data Restructuring — Pivot, transpose, group, and reshape your data into the structure you need.
- Data Formatting — Apply consistent number formats, date formats, currency symbols, and conditional formatting across your sheet.
- AI Analysis & Insights — Get a senior analyst's read on your data: trends, anomalies, and recommendations, with every number traceable to its source.
- Dashboards & Analysis Briefs — Generate a formatted analyst brief and interactive dashboard, delivered as a shareable report you can present.

How it works:
1. Open any Google Sheet
2. Go to Extensions → Columnly AI → Open Sidebar
3. Type what you want in plain English
4. Columnly confirms your intent, then delivers the results

How Columnly handles your data:
Columnly works only on the spreadsheet you open it in. Cleaning and formatting modify your sheet directly, with undo available for any change. Dashboards and analysis briefs are delivered as separate reports and don't alter your source data. See our Privacy Policy and Terms for full details.

Free plan included. Paid plans available for higher usage and advanced features.
