What Our Users Say
Been searching for something like this for months. Our Shopify store processes 500+ orders monthly and this handles everything perfectly. Date formats, tax columns, refunds - all correct.
works good, wish it had batch mode
I was spending 4-5 hours every month reformatting exports manually. This tool paid for itself in the first use. The preview feature helped me verify the mapping before paying.
exactly what i needed thx!!
Super straightforward. Upload, convert, download. No account needed which is nice. Would give 5 stars if they add Xero support.
saved me hours of work
My accountant was so happy when I sent her the converted file. No more back-and-forth about date formats or missing columns. Everything imported correctly on first try.
fast and easy 10/10 would recommend
Been using this for 6 months for monthly reconciliations. Handles all the edge cases - partial refunds, multi-line orders, currency conversions. Very reliable tool.
Good tool, does what it says. Interface could be bit better but conversion quality is excellent. Using it for my 3 Shopify stores.
Switched from A2X to this. Way simpler for my needs - I don't need real-time sync, just clean data once a month. This delivers exactly that.
finally!! something that works with QB desktop!!

Validation Questions Answered
What errors does this tool detect?
The tool checks for empty or missing feed URLs, URLs that do not start with http:// or https://, duplicate feed URLs across the file, missing feed titles, and invalid XML structure. Each error includes the row number and specific issue.
Can I validate OPML from any RSS reader?
Yes. The tool handles OPML files exported from Feedly, Inoreader, NewsBlur, Pocket Casts, Overcast, and any app that produces standard OPML 1.0 or 2.0 format.
What happens after validation?
You get a report showing valid feeds and any errors found. Download the error report to see exactly which feeds need fixing. Fix the issues in your OPML file and re-validate or convert with our other tools.
How Validation Works
1
Export from Feedly
Feedly: Organize → Export OPML (downloads feedly.opml file)
2
Export from Inoreader
Inoreader: Preferences → Import/Export → Export as OPML
3
Export from Pocket Casts
Pocket Casts: Profile → Settings → Export Subscriptions (OPML format)
4
Export from Overcast
Overcast: overcast.fm/account → Export OPML
5
Upload CSV
Upload your OPML Subscription File export file
6
Review Validation Results
Check your Opml data for errors and warnings
Issues are flagged inline with clear fix suggestions — review and correct before you import.
Why Validate OPML Before Import?
Silent Import Failures
RSS readers silently skip malformed entries during OPML import. Feeds with empty URLs, invalid protocols, or duplicate entries get dropped without warning. You think all subscriptions transferred, but some are missing. There is no error log to tell you what went wrong.
What This Tool Checks
Upload your OPML file for validation. The tool checks that every feed has a valid URL starting with http:// or https://, titles are present, no duplicate feed URLs exist, and the XML structure is valid. Get a row-level error report with specific issues to fix before importing.
Your Data Stays Private During Validation
Every Row Checked
Each record is validated against format rules. Catch errors before they reach your platform.
Runs in Your Browser
Validation happens locally. Your data never leaves your browser.
GDPR Compliant
No files uploaded, no data retained. Full EU privacy compliance.
Why Validate Before Importing?
Feed URL Validation
Checks every feed URL for valid HTTP/HTTPS format. Flags empty URLs, FTP links, and malformed addresses.
Duplicate Detection
Finds feeds with the same URL across different folders. Shows which rows are duplicates.
Missing Data Check
Reports feeds with missing titles or empty required attributes that cause import problems.
Row-Level Error Report
Get specific error messages with row numbers for every issue found. Fix problems quickly.
Browser-Based Privacy
Your subscription file processes locally. Feed URLs never leave your computer.
Instant Validation
Upload OPML, get validation results in seconds. See valid and invalid feeds at a glance.
Common Target Import Errors
Issues you might encounter when importing Source data to Target - and how we solve them
Invalid OPML/XML Structure
File is not valid OPML or XML format
Malformed XML tags or missing root element
Valid OPML 2.0 with <opml><body><outline> structure
Ensure file is valid OPML exported from an RSS reader
Re-export OPML from your RSS reader or podcast app
Empty Feed URL
Outline entry has no xmlUrl attribute
<outline text="Missing" xmlUrl="" />
<outline text="Feed" xmlUrl="https://example.com/feed" />

Find the correct RSS feed URL for the subscription
Invalid Feed URL Protocol
Feed URL does not use HTTP or HTTPS
ftp://not-valid.com/feed
https://not-valid.com/feed
Feed URLs must start with http:// or https://
Replace invalid protocols with https://
Duplicate Feed URL
Same feed URL found in multiple outline entries
https://example.com/feed (in Tech and Podcasts folders)
Remove duplicate from one folder
Each feed URL should appear only once in the OPML file
Remove duplicate entries keeping one copy

Frequently Asked Questions
Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.
No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
The tool checks for empty or missing feed URLs, URLs that do not start with http:// or https://, duplicate feed URLs across the file, missing feed titles, and invalid XML structure. Each error includes the row number and specific issue.
Yes. The tool handles OPML files exported from Feedly, Inoreader, NewsBlur, Pocket Casts, Overcast, and any app that produces standard OPML 1.0 or 2.0 format.
You get a report showing valid feeds and any errors found. Download the error report to see exactly which feeds need fixing. Fix the issues in your OPML file and re-validate or convert with our other tools.
Yes. The tool accepts both OPML files and CSV feed lists. For CSV-specific validation, you can also use our RSS CSV validator at /validate/rss-csv-subscriptions.
No. The tool validates URL format and data structure but does not fetch the URLs to check if they are online. For live feed checking, use a dedicated feed checker service.
The tool handles OPML files with thousands of feed entries. Processing happens in your browser so speed depends on your device.
Yes. Fix the reported issues in your OPML file using a text editor, then upload again to verify all errors are resolved.
