The short version

## What Nameglow does

A folder of final\_FINAL filenames takes too long to fix one file at a time. Drop it into Nameglow, choose a naming recipe and check the original and proposed names side by side before you rename.

For client handoffs, paste an old-name/new-name spreadsheet or import CSV or TSV. Nameglow matches by the original filename, so the row order does not matter. Resolve missing matches or conflicts, rename the batch and save a receipt of what changed.

In detail

## What you can do

- ### Use the spreadsheet you already have

  Paste two columns from your spreadsheet, or import a CSV or TSV file. Nameglow checks for missing, duplicate and unknown names before you apply the mapping.
- ### Save the rules you repeat

  Combine a base name, find and replace, prefixes, suffixes, case, separators and numbering. Save the combination as a recipe for the next batch.
- ### Preview before you rename

  Read the original and proposed names together, and resolve filename conflicts before applying changes. Turn on Windows filename checks when preparing a cross-platform handoff.
- ### Keep a receipt and an undo

  Export an HTML preview or a receipt of the completed rename. Undo the most recent batch, including after relaunch. File contents and extensions stay intact.
