The Scenario
Your documentation team just completed a major product refresh. Twenty Notion onboarding pages need their body content replaced with updated text — the old content is wrong, not just stale. You have a Excel workbook where column A lists the Notion page IDs and column B contains the new markdown content for each page. The pages are live and being read by new users today. Getting the updates in before tomorrow morning matters.
The bad version:
- Open the first Notion page, select all content, delete it, paste the new markdown from column B — watch Notion paste it as a single unformatted text block because Notion's paste doesn't interpret markdown.
- Switch to the markdown importer (if you know it exists), paste, confirm, then check that the heading hierarchy came through correctly — it usually hasn't.
- Repeat for 19 more pages, spending 5-8 minutes each time, manually checking that each page's structure survived the replacement.
Twenty pages at five minutes each is close to two hours of documentation work that isn't documentation work. It's plumbing.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the page IDs and new markdown content from the workbook, clears each page's existing content, and replaces it with the updated content rendered as Notion blocks — not pasted as plain text.
Column A has Notion page IDs and column B has new markdown content — replace the full body of each page with the content in column B, converting markdown to Notion block types
What You Get
- All 20 Notion pages have their existing body content cleared and replaced with the new content from column B.
- Markdown headings become Notion heading blocks, bullet lists become bulleted list blocks, bold text becomes bold text — the structure transfers correctly.
- A sidebar log confirming which pages were updated and flagging any that returned errors.
What If the Data Is Not Quite Ready
Some pages have a pinned header block that should be preserved — only replace content below it
For each page in column A, keep the first block (a callout block) intact — replace all blocks after the first with the markdown content from column B
The top callout block that says "Last updated: [date]" or similar stays in place. Only the content below it is replaced.
The new content in column B has placeholder text that needs to be filled with product-specific values before it goes in
Before replacing, substitute all instances of {{PRODUCT_NAME}} in column B with SheetXAI and {{VERSION}} with 3.2 — then replace the body of each Notion page in column A with the substituted content
Template variables are resolved before the content touches Notion.
You need to append a changelog entry at the bottom of each page rather than replacing the full body
For each page in column A, append the text from column B as a new paragraph block at the bottom of the page — do not clear existing content
Append rather than replace. Useful for adding a "What changed in this version" section without disturbing the main content.
The kill chain — substitute variables, validate no placeholder remains, replace, log page titles
For each row: substitute {{PRODUCT_NAME}} with SheetXAI and {{VERSION}} with 3.2 in column B — if any {{}} pattern remains after substitution, write "unfilled placeholder" in column C and skip that page — replace the body of all valid pages with the substituted markdown — write the Notion page title to column D as confirmation
One prompt: variable substitution, validation, conditional replacement, title confirmation. Any page with an unfilled placeholder is skipped and flagged rather than going live with broken template text.
Pages that ship with unfilled placeholders are documentation failures. The validation in the same prompt prevents them.
Try It
Get the 7-day free trial of SheetXAI and open the workbook with your page IDs and the new markdown content ready in column B. Ask SheetXAI to replace all 20 pages in one pass so users see the updated docs tomorrow morning.
