Frequently Asked Questions ​

Quick answers to common questions about EDI Paisan.

General ​

What is EDI Paisan? ​

EDI Paisan is a browser-based tool for viewing, inspecting, and transforming healthcare EDI files. It turns cryptic X12 data into human-readable information — no more counting tildes or memorizing segment codes.

What file types are supported? ​

Currently we support ANSI X12 healthcare transactions:

  • 837P — Professional claims
  • 837I — Institutional claims
  • 835 — Remittance advice (payment explanations)
  • 270 — Eligibility inquiries
  • 271 — Eligibility responses

We're actively expanding support. Have a format you need? Let us know.

Is EDI Paisan a desktop app or a web app? ​

EDI Paisan runs entirely in your web browser — no installation required. Just go to app.edipaisan.com and start using it.

Do I need to create an account? ​

No. No email needed — drop a file. An account is only for saving your work and Pro features.

What browsers are supported? ​

EDI Paisan works on all modern browsers:

  • Google Chrome (recommended)
  • Mozilla Firefox
  • Microsoft Edge
  • Apple Safari

We recommend Chrome for the best performance with large files.

Security & Privacy ​

Does my file get uploaded to your servers? ​

The contents do not. Your EDI file is processed in your browser. We do record facts about the file: filename, size, SHA-256 fingerprint, envelope counts, and — for 837s — control numbers. The same facts are recorded when you continue as a guest. If the app crashes, a filename may appear in the crash report and is removed on a best-effort basis.

See the privacy policy for the full list.

Is EDI Paisan HIPAA compliant? ​

File contents (the segments and the patient data inside them) stay in your browser. We do store the file facts listed above — including for guest sessions. A filename you chose, or a fingerprint of the file, is not the file itself, but it is still information about a file you opened.

You are still responsible for:

  • Using EDI Paisan on appropriate devices
  • Following your organization's policies
  • Not sharing screenshots containing PHI

A Business Associate Agreement (BAA) is available for Enterprise.

Can Paisan AI see my data? ​

We do not receive the contents of the files you view. We do receive the file facts listed above, for both signed-in and guest sessions, plus account information if you sign in (email, name) and crash reports (filenames stripped on a best-effort basis).

What happens if I close the browser? ​

The file contents are gone from that session. You'll need to open the file again to view it. The facts we recorded about it — filename, size, fingerprint, counts, and 837 control numbers — remain in your history.

Pro Tip

Keep your source files organized locally. EDI Paisan is a viewer, not a file store for the original EDI.

Is my connection encrypted? ​

Yes. EDI Paisan uses HTTPS for all connections, including the file facts we record.

Cancel anytime. No questions, no hassle. If you cancel mid-billing period, you'll retain access until the period ends.

Do you offer refunds? ​

Yes, for annual plans we offer a 30-day money-back guarantee. If Pro isn't right for you within the first 30 days, we'll refund your purchase in full.

Features ​

Can I edit EDI files in EDI Paisan? ​

Currently, EDI Paisan is focused on viewing and analyzing EDI files. While you can:

  • Split files (Pro)
  • Strip patient identifiers in the viewer (Free); download the cleaned file (Pro)
  • Preview JSON and XML in the app (Free); download either file (Pro)

Full editing capabilities (creating or modifying transactions) are on our roadmap but not yet available.

What's claim splitting? ​

Claim splitting takes a batch file containing multiple claims and separates them into individual files. Useful for:

  • Isolating problem claims
  • Testing with single-claim files
  • Sharing specific claims without exposing the entire batch

What's PHI anonymization? ​

PHI anonymization replaces Protected Health Information with fake but realistic data. The file structure stays intact, but patient names, IDs, dates, and other identifiers are replaced. Strip patient identifiers in the viewer for Free; download the cleaned file with Pro. Perfect for:

  • Training new staff
  • Creating test files for developers
  • Sharing examples without privacy concerns

Can I export data to Excel? ​

CSV export (opens in Excel) is Pro. There is no native Excel .xlsx download. Preview JSON and XML in the app for Free; download either file with Pro.

Does EDI Paisan validate files? ​

EDI Paisan checks structural validity (proper envelope structure, segment formatting), but it doesn't perform full compliance validation against implementation guides. For compliance checking, you'd still need a dedicated EDI validator.

We highlight obvious structural issues, but passing EDI Paisan's parser doesn't guarantee your file will pass a clearinghouse or payer's validation.

Technical ​

What's the maximum file size? ​

100MB per file. This covers the vast majority of EDI files — even large batch files from busy providers.

For truly massive files (rare in healthcare EDI), consider splitting them before upload.

Why does a large file take a while to load? ​

Parsing happens entirely in your browser using WebAssembly. While this is fast (usually under a second), very large files require:

  1. Reading into browser memory
  2. Parsing delimiters
  3. Building the segment tree
  4. Loading element descriptions

For 50MB+ files, this might take a few seconds. Once loaded, navigation is instant.

Can I use EDI Paisan offline? ​

Not currently. While processing happens locally, you need an internet connection to load the app. Offline support (via a Progressive Web App) is on our roadmap.

Does EDI Paisan support EDIFACT? ​

No. EDI Paisan is focused on ANSI X12, the standard used in US healthcare. EDIFACT (used more in international trade and non-US healthcare) is not currently supported.

Does EDI Paisan support HL7? ​

No. HL7 (Health Level 7) is a different standard used for clinical data interchange. EDI Paisan is focused on X12 administrative transactions (claims, remittances, eligibility).

Why can't EDI Paisan parse my file? ​

Common reasons:

  • Not X12 format — File might be EDIFACT, HL7, or proprietary
  • Encrypted/compressed — Unzip or decrypt first
  • Truncated — File was cut off (missing IEA trailer)
  • Exotic delimiters — We support most, but some legacy systems use unusual characters

Open the file in a text editor. Valid X12 files start with ISA and end with IEA~.

Troubleshooting ​

The page is blank or won't load ​

Try:

  1. Clear browser cache and cookies
  2. Disable browser extensions (especially ad blockers)
  3. Try a different browser
  4. Check if JavaScript is enabled

My file shows "parsing error" ​

  • Verify the file is ANSI X12 format
  • Check the file isn't encrypted or compressed
  • Ensure the file is complete (has ISA at start, IEA at end)
  • Try opening in a text editor to verify content

Search isn't finding something I know is there ​

  • Search is case-insensitive, but exact
  • Try searching for partial terms
  • Check for leading/trailing spaces in your search
  • Make sure you're searching the right file (if multiple are loaded)

The app is running slowly ​

  • Close other browser tabs
  • Try Chrome if using another browser
  • Clear browser cache
  • For very large files, expect some initial parsing time

I lost my file after refreshing ​

This is expected for the file contents. Refresh clears the viewer. Keep your source files organized locally and open them again as needed. Filename, size, fingerprint, and related facts we recorded are still in your history.
