FAQ

What types of files can be processed using this skill?

This skill supports both .xlsx and .csv file formats for creation, editing, and analysis.

Does the skill automatically generate charts or graphs?

What is required to ensure no formula errors?

All formulas in the spreadsheets must be free from errors like #REF!, #DIV/0!, #VALUE!, etc. Additionally, all assumptions should be placed in separate cells and referenced correctly in formulas.
