Practical Methods for Processing Excel Data with AI

Excel is the most used workplace tool, but functions, pivot tables, and VBA have a steep learning curve. AI makes spreadsheet processing "speak human."

1. Have AI Write Formulas
Describe your need: "Write a formula that sums values in column A greater than 100, where column B equals 'Completed.'" AI outputs the formula with explanation — just paste it in.

2. Data Cleaning
Paste messy data to AI: "Please: 1) Unify date formats 2) Remove duplicate rows (keep first) 3) Fill blank cells with 0 4) Split names and phone numbers." AI outputs cleaned data to copy back.

3. Pivot Analysis
Describe: "Summarize sales totals and averages by 'Region' and 'Month' dimensions, output as a table." AI generates results you can use directly.

4. Anomaly Detection
Paste data and ask: "Which months in this sales data look abnormal? What might be the causes?" AI does initial analysis.

5. VBA & Automation
Generate VBA code to automate repetitive tasks (batch renaming, scheduled summaries). Save as a macro and you're set.

Tool Recommendations:
1. General AI (Doubao/Kimi/Qwen): Paste data and ask directly — convenient
2. ChatExcel: Dedicated conversational spreadsheet tool — zero learning curve
3. Feishu/WPS AI: AI built into spreadsheets — no context switching

Note: For sensitive data, prefer locally deployed models or desensitize before processing.
