1. Data Import and Preparation
The first step involves exporting AliExpress review data (including star ratings, text comments, and timestamps) into spreadsheets:
- Use ImportXML/ImportHTML for automated data collection
- Structure data in columns:
ProductID,ReviewText,Rating,Date - Clean data by removing emojis, brand names, and punctuation
// Sample formula for basic sentiment scoring =ARRAYFORMULA(IF(LEN(A2:A), IFERROR( (COUNTIF(SPLIT(LOWER(A2:A), " "), "happy") - COUNTIF(SPLIT(LOWER(A2:A), " "), "defect")) /LEN(A2:A)*10, 0),""))
