The Scenario
The product team handed you an Excel worksheet with 20 rows. Each row is a bullet-point summary of a product feature launching this quarter. Your job: turn every one of them into a ready-to-schedule social caption before the editorial calendar meeting on Thursday.
You've used Planly's AI caption tool before. It's good. But you've been using it one prompt at a time — paste in a bullet, get the caption, copy it to the worksheet, go back, paste the next bullet. Twenty times.
The bad version:
- Copy the first product description from column A, switch to Planly's AI tool, paste it in, generate a caption, copy the result, switch back to the workbook, paste into column B.
- Repeat nineteen more times, losing focus somewhere around bullet eleven when you realize the captions for bullets 8 and 12 sound almost identical.
- Finish and discover you spent two hours on something that was supposed to be prep work, not the actual work.
The editorial calendar is in four hours. The captions were supposed to be done before lunch.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands what you're looking at, and through its built-in Planly integration it can read every description in column A, call Planly's AI caption generator for each one, and write the results back to column B — all in one pass.
Open the Excel worksheet with your product descriptions, open the SheetXAI sidebar, and paste this prompt:
Read every prompt in column A of this Excel table and generate a 280-character Twitter/X caption using Planly AI for each — write the output to column B
What You Get
- Column B: a ready-to-post social caption for each row in column A
- Captions generated in Planly's style, suitable for scheduling directly from Planly
- One caption per row; column A stays untouched
- If Planly's AI tool returns an error for a row, column B gets a note — no silent skips
What If the Data Is Not Quite Ready
You want captions for LinkedIn instead of X (longer format, more professional tone)
Read every prompt in column A of this Excel table and generate a LinkedIn caption using Planly AI for each — aim for 150–300 characters and write the result to column B
You want two variants per row so you can A/B test
Read every prompt in column A of this Excel table and call Planly AI twice per row — write the first caption variant to column B and the second to column C
Some descriptions in column A are blank and should be skipped
For each non-empty row in column A of this Excel table, call Planly AI to generate a 280-character caption and write the result to column B — leave column B blank for any rows where column A is empty
Full caption batch: generate captions, add hashtags, flag long ones, and mark the batch done
For each product description in column A of this Excel table, call Planly AI to generate a caption and write it to column B — add 3 relevant hashtags to column C, flag any caption in column B that exceeds 280 characters in column D as 'Too long', and write 'Caption batch complete' into cell F1 after all rows are processed
One prompt handles caption generation, hashtag suggestions, and length validation across all 20 rows.
