Put the IRIS CSV checker on your website
Give clients a safe way to check their 1099 CSV before they upload it to IRIS. Paste the code below into any page of your site. It is free, and nothing your clients check is uploaded anywhere.
Embed code
Copy this into your website, for example a client resources page or a 1099 filing article:
Works on WordPress (Custom HTML block), Squarespace (Code block), Wix (Embed HTML) and plain HTML sites. Keep the credit line under the frame.
Why it is safe for client data
- The checker runs inside your visitor's browser. The file is never sent to this site, and it is not sent to yours either.
- The frame is on a different domain, so neither your page nor any other script on it can read what is checked.
- No accounts, cookies or tracking in the frame.
What your clients get
- Checks for every IRIS formatting rule on Forms 1099-NEC and 1099-MISC, with safe automatic fixes.
- Conversion from QuickBooks exports, Excel sheets and old FIRE files.
- Upload-ready files split at 250 records and 100KB.

Frequently asked questions
Does it cost anything?
No. The embed is free. Please keep the credit line under the frame.
Can I embed the checker for 1099-INT, 1099-R or other forms?
The embed covers 1099-NEC and 1099-MISC. For other forms, link to the form page from the IRIS CSV templates list.
Will the frame resize itself?
No. It has a fixed height of 900 pixels and scrolls inside. Change the height value in the code if your layout needs it.
