What is bulk scheduling on social media?

Definition: Bulk scheduling is loading many social media posts into a scheduling tool at once, usually from a spreadsheet or CSV file, with each post’s text, date and time, instead of scheduling them one by one.

Also called: Bulk upload, CSV scheduling

Updated October 11, 2026

How it works

You prepare a file with one row per post. Each row holds the post text, the date and time it should go out, and optionally a link to an image or video. The scheduler reads the file, shows any rows with problems, and creates a scheduled post for every valid row.

Bulk Upload takes a CSV with the columns content, scheduled_at and an optional media_url, up to 200 rows and 2 MB per file, on every plan. You choose the platforms for each upload. XLSX and JSON files, including files from Google Drive or Dropbox, go through the Scheduling Assistant instead.

Common mistakes

  • Ambiguous dates: use a full date and time format and say which time zone it is in.
  • Text over a platform’s character limit: check the longest rows before uploading.
  • Media links that are private or expire: the scheduler must be able to download them.
  • The same text on every network: tailor versions per platform after import.

Example

A store prepares 30 product posts for the month in a spreadsheet, one per day at 9:00, each with an image URL. It exports the sheet as CSV, uploads it once, picks Pinterest and LinkedIn, and all 30 posts appear in the calendar ready to review.
