1. STEP 01

   Add the original and revised versions

   Choose pasted text or file selection. Both files must use the same format. Use Swap if you need to reverse their order.

2. STEP 02

   Choose comparison settings

   The default settings work for most comparisons. Specify exceptions only when you need to ignore spaces or similar differences. For file comparisons, review the temporary upload and deletion information.

3. STEP 03

   Check the differences

   Select Check differences to review counts and highlighted additions, deletions, and changes. Use Previous difference and Next difference to navigate, and switch between side-by-side and single-column views.

4. STEP 04

   Save the report

   Select Save report to download the result. When you finish a file comparison, select Finish and delete to end the job.

Pasted text

Compares the two texts by line and character. This is not an AI tool for comparing semantic similarity.

Supported files

Supports two files of the same format: Word (.docx), PDFs with selectable text, CSV, or TXT. Specify the encoding of CSV and TXT files when needed.

Differences to ignore

You can separately ignore line endings, trailing spaces, repeated spaces, blank lines, letter case, and full-width or half-width letters, numbers, and symbols. Ignored differences are omitted from the result, so choose only the options you need.

Matching CSV rows

Rows can be matched using values in a selected column. Column A is column 1. Select a column containing an identifier or another suitable matching value.

Pasted text is compared entirely in your browser. File comparisons temporarily upload files to this site’s server. Data is deleted when saving, finishing, cancelling, or when processing fails. Interrupted data also becomes unavailable at the deadline shown on screen. Review the upload and deletion information before starting.
