Pinterest CSV checker for bulk upload errors
This Pinterest CSV checker reads your bulk upload file in your browser and lists every row that would fail or publish wrongly, with the fix for each. Your file is not uploaded: it never leaves this tab.

How this Pinterest CSV checker works
Drop in your CSV
Choose the file you saved from your spreadsheet, or paste its text. It is read in this browser tab and never sent to a server.
Read the report
Every problem comes with its row, the column, what is wrong and how to fix it. Errors are rows Pinterest would reject or publish wrongly. Warnings are worth a look.
Fix and download
Where a fix is mechanical, the tool makes it: trimmed spaces, one-line descriptions, dates in UTC, files split at 200 pins. It never fills in a missing value or shortens your text.
Where the rules come from
The rules are the ones Pinterest states on its bulk upload help page: up to 200 pins per file, a title of up to 100 characters, a description of up to 500, a direct link to a public image or video file, and publish dates written as yyyy-mm-ddThh:mm:ss in UTC (a space in place of the T also worked in our test). Pinterest can change them, so a file this tool passes can still be refused. This tool is built by InsightPins and is not affiliated with or endorsed by Pinterest.
What the Pinterest CSV checker looks for
The file
Semicolons or tabs where Pinterest expects commas, a byte-order mark added by Excel's "CSV UTF-8", more than 200 pins in one file, a header row pasted in twice, and a row with too many or too few fields because a comma inside a description was not put in quotes.
Each row
A missing title, board or media link, a title over 100 characters, a description over 500 or split over several lines, a link that is not a full web address, a media link that points at a Google Drive, Dropbox or Canva page instead of the file, and a video with no thumbnail.
Publish dates
A date in the wrong format, one that is not a real calendar day, one already in the past, one a spreadsheet app has rewritten as 3/4/2026, one with no time, and one more than 30 days ahead. Dates are read as UTC, the way Pinterest reads them.
Images, if you ask
A separate button loads each image link in your browser and reports the ones that do not load: a broken link, a login-only file, or a page that is not an image. It also notes pictures that are not 2:3. Your image host sees those requests.
One file, four problems
Take a file of three pins. The first is fine. The second links to a Google Drive page instead of the picture, and its date reads 10/7/2026 6:00 PM, which a spreadsheet has rewritten from a proper date and which could be 10 July or 7 October. The third has a 104 character title and a link that starts with http://.
The checker lists all of that by row. For the date it asks whether your file writes the day first or the month first, and in which time zone, then converts it to UTC. It does not guess, because a wrong guess would schedule the pin on the wrong day.
The Drive link and the title it leaves to you. Only you know which picture belongs there and how to shorten your own words.
What Pinterest accepted when we tried it
These are our own observations from one business account on 1 October 2026. They are not Pinterest statements, and Pinterest may change how it works.
- CSV pins were not held to the 10 pin queue. Pinterest's one-at-a-time scheduler holds 10 pins. Three uploaded files put 21 pins in Scheduled Pins together.
- A second file stacked on the same days. It did not replace the first.
- A date 35 days ahead was accepted. The scheduler stops at 30 days, and the help page does not say whether a CSV can go further.
- Pins took about two hours to appear. The upload confirmation says problems are reported by email, so check Scheduled Pins on your profile before assuming a file worked.
What this Pinterest CSV checker does not do
- It cannot see what Pinterest does after the upload. Account limits, rows refused later and whether a pin published are visible only in your Pinterest account and your email.
- It never logs in, uploads or posts. You upload the file yourself. The tool asks for no Pinterest password and does not automate your account.
- It does not judge a pin. It checks that a row is well formed, not whether the pin will earn saves, clicks or impressions.
- It cannot always tell a broken image from a blocked one. A host that blocks other websites can fail here and still work for Pinterest, so open the link yourself.
Questions, answered
A Pinterest CSV checker reads the file you plan to bulk upload and lists every row that would fail or publish wrongly, such as a title that is too long, a share page where a picture link should be, or a date a spreadsheet has rewritten. This one also fixes what can be fixed mechanically and downloads a cleaned file.
No. The file is read and checked in your browser tab and is not sent to us or anyone else. The one exception is the optional image check, which you start with a button: it makes your browser load each image link in the file, so the sites hosting those images see the requests.
According to Pinterest's help page, up to 200 pins per file, a title of up to 100 characters, a description of up to 500, a board, a direct link to a public image or video file, and publish dates written as yyyy-mm-dd hh:mm:ss in UTC. Videos need a thumbnail. The checker tests each of these.
The success message only means the file was accepted for processing. In our test Pinterest took about two hours to create the pins and said problems are reported by email. Check Scheduled Pins on your profile and your inbox, including spam, before you upload again.
It reads publish dates as UTC, which is what Pinterest expects. For a date that is not in that form it converts using the time zone you choose, including daylight saving changes. A date like 3/4/2026 could be 3 April or 4 March, so it asks which order your file uses instead of guessing.
No. It never logs in to Pinterest and never posts. It checks and cleans the file, and you upload it yourself with Pinterest's bulk upload.
