How it works

Open a file and search right under the column headers.

Narrow large CSV or Excel files exported by forensic tools down to just the rows you need with per-column conditions.

  1. Open a file

    Choose a CSV, XLS, or XLSX file with File → Open (Ctrl+O), or drag it onto the window.

  2. Search by column

    Type a condition in the search box under a column header and press Enter. Enter conditions in several columns to show only rows that match all of them.

  3. Sort and view details

    Click a column header to sort, select a row, and open Row details to see every column’s value.
