Explain what a spreadsheet column means
Works with ChatGPT · Claude · Copilot
Make sense of a confusing column in a spreadsheet you inherited.
The problem
Inherited spreadsheets have cryptic columns no one documented.
What this skill does
AI infers what a column likely represents from its header and sample values.
When to use it
- Use when you open a sheet and a column is unclear.
Juni’s tip
Juni says: check a few sample values before trusting any column.
The prompt
Try it live
Fill in the blanks — your ready-to-use prompt builds as you type.
Weak vs. better
what is this column
Given this column header and sample values — [header and examples] — explain what it most likely represents, its probable unit or format, and how it might be used. Flag if the values look inconsistent.
Why this works
Inferring meaning from header plus samples lets you use an undocumented sheet safely.
Practice task
Take a confusing column and have its likely meaning explained.
Self-check
- Explains the column's likely meaning
- Notes the probable unit or format
- Flags inconsistent-looking values
Common mistakes to avoid
- Guessing from the header alone
- Ignoring odd or inconsistent values
- Assuming a format without checking samples
