The Scenario
The copy team lead sent a message on Tuesday asking for spoken transcripts from the brand's top 20 TikTok videos. The social media manager already has all 20 URLs in a Google Sheet from last month's performance review. What the copy team actually needs is the words — the hooks, the transitions, the call-to-action phrasing — so they can adapt them into blog post intros and email subject lines. Nobody hired the social media manager to manually watch 20 videos and type out what was said.
The bad version:
- Open each TikTok URL in a browser, check whether native captions exist, try to find a way to extract them.
- Discover that TikTok's own interface does not expose transcript text in a copyable format. Start googling third-party tools.
- Copy-paste what you can find, realise the formatting is inconsistent across videos, spend 20 minutes cleaning up the first three rows.
The copy team wants this by Thursday. At the rate the manual approach is going, that is not happening.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the URLs in your sheet and, through its built-in Supadata integration, fetches spoken transcripts from TikTok and Instagram videos — including AI-generated captions when native captions are missing — and writes the text back into the sheet.
For each TikTok or Instagram URL in column A, get the Supadata transcript and write the plain-text transcript into column B — if AI-generated captions are needed because native captions are missing, use those
What You Get
- Column B populated with plain-text transcript for each video, with punctuation cleaned up.
- AI-generated captions used automatically as a fallback when native captions are unavailable — no manual intervention required.
- The full batch of 20 videos processed in one operation.
- Output ready for the copy team to read, highlight, and adapt without any reformatting.
What If the Data Is Not Quite Ready
The sheet includes a mix of platforms — TikTok, Instagram, and YouTube
Column A has a mix of URLs from all three platforms.
For each URL in column A, use Supadata to fetch the transcript and write it into column B — also identify the platform (TikTok, Instagram, or YouTube) and write that into column C
Some videos are private or have been deleted since the list was made
Column A may include stale URLs from a performance report that was run three months ago.
Use Supadata to fetch transcripts for every URL in column A, write available transcripts into column B, and write 'Unavailable' into column B for any video that returns an error — log the error type in column C
You only want transcripts for videos with more than 100K views
Column B already has view count data from a previous pull.
Use Supadata to fetch transcripts only for rows where column B shows a view count over 100000 — write the transcript into column C and skip other rows
You want the transcript plus a one-line summary in the same row
The copy team asked for a brief summary of the hook and CTA alongside the full transcript.
For each TikTok URL in column A, use Supadata to fetch the transcript, write it into column B, then summarise the opening hook and the call-to-action in one sentence and write that into column C
The pattern: request the data pull and the editorial summary in a single prompt — no second pass needed.
Try It
Get the 7-day free trial of SheetXAI and open any Google Sheet with a column of TikTok or Instagram URLs and ask it to pull the spoken transcripts in one operation. You might also find the spoke on fetching YouTube transcripts useful if your content research spans platforms.
