Share Comparisons Instantly: New URL Parameter Feature

Introducing URL Parameter File Loading

We’re excited to announce a powerful feature that makes sharing and automating file comparisons easier than ever: URL Parameter File Loading. You can load files directly into any TextCompare tool using URL parameters, enabling instant comparison sharing and automated workflows.

This feature is available across all comparison tools:

Text Comparison
PDF Comparison
Excel/Spreadsheet Comparison
CSV Comparison
Image Comparison

How It Works

Simply add original= and modified= parameters to any TextCompare URL with publicly accessible file URLs:

https://textcompare.org/?original=https://example.com/file1.txt&modified=https://example.com/file2.txt

The tool will:

Automatically fetch both files from the provided URLs
Load them into the appropriate comparison view
Trigger the comparison automatically (when both files load successfully)

Supported URL Formats

The feature supports various URL formats and automatically handles:

HTTP and HTTPS URLs
URL encoding (both encoded and plain URLs work)
Different file types based on the tool
CORS-enabled public URLs

Use Cases

1. Share Comparison Links

Instead of sending files back and forth, share a single link that loads both files:

https://textcompare.org/pdf/?original=https://mysite.com/v1.pdf&modified=https://mysite.com/v2.pdf

Perfect for:

Code review discussions
Document version comparisons
Collaborative data analysis
Bug reports with before/after screenshots

2. Automate Quality Assurance

Integrate comparisons into your CI/CD pipeline or automated testing:

# Generate comparison URL in your test scripts
COMPARISON_URL="https://textcompare.org/csv/?original=${EXPECTED_OUTPUT}&modified=${ACTUAL_OUTPUT}"
echo "View differences: $COMPARISON_URL"

3. Documentation and Tutorials

Embed live comparison examples in documentation:

[View the difference between versions](https://textcompare.org/?original=https://docs.example.com/old.txt&modified=https://docs.example.com/new.txt)

4. GitHub Integration

Compare files from GitHub repositories:

https://textcompare.org/?original=https://raw.githubusercontent.com/user/repo/main/file.js&modified=https://raw.githubusercontent.com/user/repo/dev/file.js

5. Cloud Storage Integration

Load files directly from cloud storage services:

https://textcompare.org/excel/?original=https://your-bucket.s3.amazonaws.com/report-jan.xlsx&modified=https://your-bucket.s3.amazonaws.com/report-feb.xlsx

Important Considerations

CORS Requirements

For security reasons, the files you want to load must be accessible via CORS-enabled URLs. The server hosting the files needs to allow cross-origin requests.

If you encounter CORS errors, consider:

Using a CORS proxy service
Hosting files on CORS-enabled platforms (GitHub Pages, AWS S3 with CORS, etc.)
Using the traditional file upload method

Privacy & Security

Files are fetched directly from the URLs you provide
All processing happens in your browser
No data is sent to our servers unless you explicitly choose to save the comparison online
URLs are visible in the browser address bar, so only use publicly accessible files

URL Encoding

URLs are automatically decoded, but for best results:

Use properly encoded URLs (e.g., %20 for spaces)
Avoid special characters in filenames when possible
URLs can be passed both encoded and unencoded

Getting Started

Or create your own comparison URL:

Choose a comparison tool (text, PDF, Excel, CSV, or image)
Get publicly accessible URLs for your files
Construct the URL: https://textcompare.org/[tool]/?original=[url1]&modified=[url2]
Share the link!
