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!!

2

RSS.app: Profile → Import/Export → Export CSV (columns: xmlUrl, title, description, sourceUrl)
3
Export from spreadsheet
Google Sheets or Excel: File → Download as CSV. Ensure feed URLs are in a column named feed_url or xmlUrl
4

Common Conversion Questions
What CSV columns are needed?
Only a feed URL column is required. The tool auto-detects columns named feed_url, xmlUrl, url, rss_url, or similar. Optional columns for title, site URL, folder, and description are mapped automatically when present.
How do I import OPML into my RSS reader?
In Feedly, go to Organize then Import OPML. In Inoreader, go to Preferences then Import/Export. Most RSS readers have an Import OPML option in settings. Upload the downloaded .opml file directly.
Does it preserve folder structure?
Yes. If your CSV has a folder or category column, the tool creates nested OPML folders. Path notation like Tech/Programming creates a Programming folder inside Tech.
Why You Cannot Just Rename CSV to OPML
The Column Mapping Problem
RSS readers expect OPML 2.0 with specific XML attributes like text, xmlUrl, htmlUrl, and type. A CSV spreadsheet has none of this structure. Column names vary wildly between sources. Some use feed_url, others xmlUrl or just url. Without proper mapping, your feeds will not import correctly.
What This Tool Does
Upload your CSV or Excel file with feed URLs. The tool automatically detects your column layout, validates every feed URL, removes duplicates, builds proper folder hierarchy from your category column, and generates valid OPML 2.0. Import directly into Feedly, Inoreader, or any RSS reader.
Your Conversion is Secure
Browser-Only Processing
All conversion runs in your browser. Files are never uploaded to any server.
No Data Retention
Nothing is stored after conversion. Close the tab and your data is gone.
GDPR Compliant
Full EU data protection compliance. Your privacy rights are fully protected.

Common OPML 2.0 Subscription File Import Errors
Issues you might encounter when importing RSS/Podcast Subscriptions CSV data to OPML 2.0 Subscription File - and how we solve them
No Feed URL Column Found
CSV must have a column with feed URLs (feed_url, xmlUrl, url, etc.)
CSV with columns: Name, Website
CSV with columns: feed_title, feed_url, site_url
Add a column named feed_url or xmlUrl with RSS/Atom feed URLs
Rename your URL column to feed_url
Invalid Feed URL
Feed URLs must start with http:// or https://
www.example.com/feed
https://www.example.com/feed
Ensure all feed URLs include the protocol (https://)
We auto-prepend https:// to URLs missing protocol

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.
Only a feed URL column is required. The tool auto-detects columns named feed_url, xmlUrl, url, rss_url, or similar. Optional columns for title, site URL, folder, and description are mapped automatically when present.
In Feedly, go to Organize then Import OPML. In Inoreader, go to Preferences then Import/Export. Most RSS readers have an Import OPML option in settings. Upload the downloaded .opml file directly.
Yes. If your CSV has a folder or category column, the tool creates nested OPML folders. Path notation like Tech/Programming creates a Programming folder inside Tech.
Feeds without a folder or category value are placed at the root level of the OPML file, outside any folder.
Yes. The tool accepts .csv, .xls, .xlsx, and .xlsm files. Excel files are parsed automatically.
The tool validates all URLs and flags any that do not start with http:// or https://. Invalid URLs are reported in the preview so you can fix them before downloading.
No hard limit. The tool handles CSV files with hundreds or thousands of feed entries.
