How to Bulk Upload and Schedule Pinterest Pins from a CSV

Step by step

1. 1

   Prepare your pin images and gather your pin data

   Collect all the images you plan to pin into a single folder. As of June 2026, Pinterest standard pin images perform best at a 2:3 aspect ratio (e.g. 1000 × 1500 px) — see the Pinterest pin size guide for current recommended dimensions. For each image, note the pin title (up to 100 characters), description (up to 500 characters), destination URL, and the target board name.

   Tip: Run each destination URL through SocialKit’s free UTM builder before you add it to the spreadsheet — tagged links let you attribute Pinterest traffic precisely in Google Analytics 4.

2. 2

   Build the CSV file from SocialKit’s template

   In SocialKit, navigate to the Publish section and look for the bulk import or CSV upload option. Download the provided CSV template so your column headers match exactly what the importer expects. As of June 2026, a typical Pinterest CSV includes columns for image URL or file path, pin title, description, destination link, board name, and scheduled date/time in ISO 8601 format (e.g. 2026-08-14T09:00:00). Fill one row per pin.

   Tip: Keep image filenames free of spaces and special characters — some import tools trip on unusual filenames. Rename files to something like pin-001.jpg before you start.

3. 3

   Validate your CSV before uploading

   Open the completed file in a spreadsheet app and scan for common errors: missing board names, blank destination links, date formats that do not match ISO 8601, or rows where the image path is broken. A single malformed row can cause the entire batch to fail or skip silently, so a two-minute check here saves significant rework. Confirm that every scheduled date is in the future and that no two pins share the exact same timestamp on the same board — Pinterest may rate-limit rapid consecutive pins to the same destination.

4. 4

   Upload the CSV to SocialKit and map the columns

   In SocialKit’s bulk import screen, upload your CSV file. SocialKit will display a column-mapping step where you confirm which CSV column corresponds to which pin field (title, description, link, board, date). Correct any mismatches before proceeding. As of June 2026, the importer flags rows with missing required fields so you can fix them without having to re-upload the whole file.

   Tip: If you are scheduling images that are not yet hosted online, check whether SocialKit’s importer supports local file upload via a separate media import step or requires image URLs. The exact supported method may differ — consult the in-app help for the current behaviour.

5. 5

   Review the batch in the content calendar

   After a successful import, switch to the calendar view in SocialKit and filter by your Pinterest account. You should see each pin plotted on its scheduled date. Drag and drop any that land on a day you want to avoid (holidays, already-crowded slots), or check the Pinterest best-time-to-post data to redistribute across the windows with historically strongest engagement for your audience.

6. 6

   Confirm auto-publish is active and schedule the batch

   Pinterest standard image pins support direct publishing via the Pinterest API for Business accounts as of June 2026. In SocialKit’s scheduler, verify that each pin shows "auto-publish" rather than a reminder notification. Once confirmed, approve the batch — SocialKit will publish each pin to its assigned board at the scheduled time without requiring you to be at your desk.

   Tip: Do a quick live check 10–15 minutes after the first scheduled pin fires to confirm it appears on the board with the correct image, title, description, and destination link. Catching a mapping error early lets you edit the remaining queued pins before they go out.

7. 7

   Monitor performance and re-queue top performers

   Once pins have been live for at least 48 hours, review click and save data inside SocialKit’s analytics or directly in Pinterest Analytics. Pins that perform above average are candidates for re-scheduling to a secondary board or repurposing into a video pin. Because Pinterest content has a much longer distribution tail than most platforms, a strong pin can drive traffic for months — give it adequate time before drawing conclusions.

Best practices

• Pin to a maximum of one or two boards per image per day — Pinterest’s spam filters, as of June 2026, can suppress accounts that flood multiple boards with the same URL in a short window.
• Write a unique description for each pin even when the image and destination link are the same; duplicate descriptions across many pins can reduce distribution over time.
• Schedule pins during the time windows your specific audience is most active on Pinterest rather than generic industry averages — use the /best-time-to-post/pinterest starting points and refine against your own Pinterest Analytics.
• Keep destination links consistent and working: a high-quality pin pointing to a 404 wastes both the impression and potential board authority.
• Spread your batch across several weeks rather than front-loading all pins into a few days — steady cadence signals an active, trustworthy account to Pinterest’s distribution algorithm.
• After uploading a large CSV, scan the content calendar view for accidental duplicates or mis-assigned boards before the first pin fires.
