Late Social Media Integration in SheetXAI

Overview

SheetXAI's Late integration allows you to post to 13+ social media platforms directly from your spreadsheet. Create posts, schedule them for specific dates and times, bulk post from multiple rows, and import your posting history — all through simple chat commands. Late acts as the bridge between your spreadsheet and all your social media accounts.

Platform Availability: Late integration works in both Google Sheets and Excel versions of SheetXAI.

Supported Social Media Platforms

Late supports posting to 13+ platforms, including:

  • Twitter / X
  • LinkedIn
  • Instagram
  • TikTok
  • Facebook
  • Pinterest
  • YouTube
  • And more

You connect your social media accounts through Late, and SheetXAI posts to them via Late's API.

Before You Start: Late Setup

Step 1: Set Up Your Late Account

Before using the Late integration in SheetXAI, you need a Late account with connected social media profiles:

  1. Sign up at Late — Create an account at late.so
  2. Connect your social media accounts — In Late's dashboard, connect all the social media platforms you want to post to
  3. Get your API key — Find your API key in your Late account settings

Step 2: Configure Late in SheetXAI

Open SheetXAI Settings

  • Click the Settings button in the SheetXAI sidebar
  • Navigate to the Social Media section

Enter Your Late Details

  • Late API Key: Your API key from Late

Important: Make sure your social media accounts are already connected within Late before trying to post from SheetXAI. SheetXAI posts through Late, so accounts must be connected there first.

How Late Integration Works

SheetXAI reads your spreadsheet data and sends it to Late for posting. Each row can become a separate social media post. You can specify which platforms to post to, when to schedule posts, and attach media — all from your spreadsheet data or chat commands.

Getting Started

Step 1: Prepare Your Content

Organize your social media content in a spreadsheet:

Recommended Columns:

  • Content — The text of your social media post
  • Platforms — Which platforms to post to (e.g., "twitter,linkedin")
  • Media — URLs to images or videos to attach
  • Scheduled For — Date and time for scheduled posts (e.g., "2026-03-01 10:00 AM EST")

Step 2: Post to Social Media

Important: Before making your request, click the + icon next to "current sheet" and select Late (if not already added).

Use natural language to specify your posting preferences:

Example Requests:

  • "Post this to Twitter and LinkedIn"
  • "Schedule these posts for tomorrow at 9am"
  • "Bulk post these rows to Instagram"
  • "Post this with the image in column B to all my connected platforms"

Creating Posts

Single Post

Post a single piece of content to one or more platforms:

Example:

ContentPlatforms
Check out our latest blog post on AI productivity tips!twitter,linkedin

Request: "Post this to Twitter and LinkedIn"

Bulk Posting

Post multiple rows of content at once:

Example:

ContentPlatformsMedia
Excited to announce our new feature!twitter,linkedin,instagramhttps://image1.jpg
Behind the scenes of our latest updateinstagram,tiktokhttps://image2.jpg
Tips for better spreadsheet workflowstwitter,linkedin

Request: "Post all these rows to social media"

Result: Each row is posted to its specified platforms. Rows with errors get clear error messages without stopping the rest.

Smart Defaults and Skip Logic

When bulk posting, SheetXAI uses smart defaults:

  • Missing platforms: Uses your default connected platforms
  • Empty rows: Automatically skipped
  • Incomplete rows: Rows missing required content are skipped with a note

Scheduling Posts

Schedule for a Specific Time

Schedule posts for future publishing with timezone support:

Example:

Request: "Schedule these posts using the dates in column C"

Scheduling Tips

  • Include timezone: Always specify your timezone (EST, PST, UTC, etc.) to ensure posts go out at the right time
  • Future dates only: Scheduled times must be in the future
  • Bulk scheduling: Schedule a week's or month's worth of content from one spreadsheet

Attaching Media

Images and Videos

Attach media to your social media posts by including URLs in your spreadsheet:

Example:

ContentMediaPlatforms
Our new product is here!https://example.com/product-photo.jpginstagram,twitter

Request: "Post these rows with the images in column B"

Media Tips

  • Use direct image/video URLs (not sharing links)
  • Check platform-specific requirements (Instagram requires images, some platforms have size limits)
  • Ensure media URLs are publicly accessible

Importing Post History

Import All Posts from Late

Pull your existing post history from Late into a spreadsheet for review and analysis:

How to Import:

  1. Make sure Late integration is added — Click the + icon next to "current sheet" and select Late

  2. Request the import — Ask SheetXAI:

    • "Import all my posts from Late"

    • "Get all my Late posts"
  3. SheetXAI will process — The AI will:

    • Connect to your Late account
    • Retrieve all your posts
    • Create a new sheet with your post history

Imported Data Structure

When you import posts, SheetXAI creates a sheet with columns including:

  • Post ID — Late post identifier
  • Content — Post text
  • Platforms — Which platforms it was posted to
  • Status — Posted, scheduled, draft, etc.
  • Scheduled For — Scheduled date and time
  • Created At — When the post was created

Use Cases for Import

  • Performance analysis: Analyze your posting patterns
  • Content recycling: Find top-performing posts to repurpose
  • Calendar review: See your posting schedule at a glance

Viewing Connected Accounts

Best Practices

Content Preparation

  • Platform-specific content: Tailor your message length and style for each platform (Twitter is short, LinkedIn can be longer)
  • Test with one post: Try a single post first before bulk posting
  • Review before bulk posting: Double-check your spreadsheet — posts can't be recalled once published
  • Use skip logic: Leave rows empty or incomplete if you want them skipped during bulk operations

Scheduling

  • Always include timezone: Prevent posts from going out at the wrong time
  • Schedule in advance: Batch your content creation and schedule a week or month ahead
  • Stagger posting times: Don't post to all platforms at the same time

Media

  • Use direct URLs: Ensure image and video URLs point directly to the file
  • Check platform requirements: Each platform has different media size and format requirements
  • Test media first: Verify images display correctly before bulk posting

Troubleshooting

Connection Issues

Symptom: Posts fail with authentication errors

Solution:

  • Verify your Late API key is correct in SheetXAI Settings
  • Check that your Late account is active
  • Ensure your social media accounts are still connected in Late's dashboard

Posts Not Appearing

Symptom: SheetXAI says success but posts aren't visible

Solution:

  • Check if posts were scheduled instead of posted immediately
  • Verify the correct platforms were selected
  • Check Late's dashboard for post status and any platform-specific errors

Media Not Attaching

Symptom: Posts publish without attached images or videos

Solution:

  • Verify media URLs are direct links (not sharing pages)
  • Check that media URLs are publicly accessible
  • Ensure media meets platform size and format requirements

Scheduling Issues

Symptom: Posts go out at the wrong time

Solution:

  • Always include timezone in your scheduled time
  • Verify the date format is correct
  • Ensure scheduled times are in the future
