About this comparison tool
Privacy-first comparison
Text and spreadsheets are handled in your browser, without registration or a file-upload server. Avoid pasting secrets into untrusted shared devices.
Choose the right comparison
Use text for paragraphs, PDF for selectable PDF content, Excel or CSV for keyed tables, lists for repeated entries, and the product checker for changing specifications.
Frequently asked questions
Are my files uploaded to your server?
No. The comparison logic runs in your browser. For PDF files, the PDF parsing library is loaded from a third-party content delivery network the first time you use it; the contents of your files are processed locally.
Can I compare Excel files without matching row positions?
Yes. Select one or two matching key columns, such as an order number and postcode. Rows can be sorted differently.
Can I download the differences?
Yes. You can copy results, download TXT or CSV, or use your browser to print or save a PDF report.
