Compare two versions of a document, text PDF or spreadsheet side by side on your PC. See the summary and the first 10 changes for free. Pro shows every change and saves PDF or XLSX change reports. Your files are never uploaded.

Documents: words, moved paragraphs and formatting

• Compare .docx documents word by word, including added, deleted and reworded text and paragraphs that moved, even when they were edited too.
• See changes to bold, italic, underline, font, size and color.
• Compare tables, footnotes, endnotes, headers, footers and text boxes. Tracked changes are compared as accepted.
• Old .doc files are converted locally before comparison (beta).

PDF: compare the original pages or read as text

• View the original PDF pages side by side with boxes around changes. Synchronized scrolling follows the same text even when pages were added or removed.
• Running headers, footers and page numbers are ignored by default.
• Switch to a paragraph-by-paragraph text view.

Spreadsheets: match rows by a key

• Compare .xlsx, .xls and .csv files. A key column is found automatically; Pro also lets you choose it.
• Match corresponding rows despite sorting or inserted rows, and see changed values, formulas and added or deleted rows, columns and sheets.
• When a total such as =SUM(F2:F51) expands after rows are inserted, the app distinguishes a range adjustment from a formula change.
• .xls workbooks are compared by values only.

Review and report changes

Filter the change list by type and move to the previous or next change. Pro exports a PDF or XLSX report; PDF reports can include changed original PDF pages with the changes boxed.

Free and Pro

1-week free trial. Microsoft Store handles subscriptions, prices and trial eligibility.

Pro options include ignoring case, spaces, number formatting, PDF headers and page numbers, or formatting changes, and choosing the spreadsheet key column. Pro is required for files over 100 PDF pages, about 120 document pages or 10,000 spreadsheet rows.

How to compare two versions

1. Open the original and revised files of the same kind.
2. Read the summary and browse the highlighted changes side by side.
3. With Pro, adjust comparison options, review all changes and save a PDF or XLSX report.

Measured results and limits

The test pairs described in the app's Store listing used an original and an edited copy with a known set of changes, made for the tests or taken from public files. These are measured results for those pairs, not a guarantee for every file.

• Documents: 38 of 39 pairs exactly right; the remaining pair reported one extra moved paragraph.
• Text PDFs: 29 of 32 pairs exactly right. On the hardest real-world PDF set, 98% of changed words were found and 96% of reported changes were real changes.
• Spreadsheets: 36 of 36 pairs exactly right, including a 100,000-row workbook that took about 2.4 seconds.

• Scanned PDFs containing only images are not supported; the app tells you when it cannot find text.
• PDF text is compared in reading order. Complex tables and drawings can produce a different text order. Korean PDFs with words split across lines and footers on table-heavy pages are known weak spots.
• .doc conversion is beta, and .xls comparisons cover values only.
