Each file needs a tracking number (revision + status + title) and a transmittal folder. Name it — build one under By tracking number, or drag onto a row under From a list (loaded from the archive/MDL or pasted from Excel) — then route it under By transmittal.

ZDDC Classifier

Turn a messy folder of project files into clean, correctly-named ZDDC documents — organized by tracking number and transmittal — without ever changing your originals.

Your workspaces

① Classify & copy recommended · non-destructive

Build a tidy copy of a project in a separate output folder. Your source files are only ever read, never renamed or moved.

New workspace → pick a folder. It scans once and saves to this browser, so you can close the tab and pick up later.
Preview a file (single-click it in the left tree) to see what it actually is.
Drag it onto the right pane — onto a tracking-number folder (the folder path becomes the number, the leaf is the revision, e.g. A (IFR)), and onto a transmittal (party + date + TRN/SUB + sequence).
Copy when ready → choose an output directory; renamed copies are written as <party>/<transmittal>/<name>, with duplicates detected.

② Rename in place edits your files

A quick spreadsheet for a folder you own: fill in tracking number, revision, status and title, and rename the files on disk.

Click Use Local Directory (top bar) to open a folder.
Switch the toggle to Rename in place.
Edit cells (or paste columns from Excel); names already in ZDDC format are parsed automatically and validated as you type.
Save All renames the files where they sit.

Everything runs in your browser — no files are uploaded. Tip: if your folder lives on OneDrive/SharePoint, set it to “Always keep on this device” first for a much faster scan.

What is the Classifier?

The Classifier is a spreadsheet-based tool for renaming files to ZDDC naming conventions. It reads a folder of files and presents them in an editable grid where you can set tracking number, revision, status, and title — then saves the renamed files back to disk.

Getting Started

Click Use Local Directory to open a folder containing files to rename.
The folder tree on the left shows all sub-folders. Click a folder to load its files.
Edit cells in the spreadsheet to set the new filename components.
Click Save All (or save individual rows) to rename the files on disk.

Folder Tree

Multi-select: Hold Ctrl and click to select multiple folders. Hold Shift to select a range. Files from all selected folders are shown together.
Hide Compliant: Hides folders where all files already have valid ZDDC names, letting you focus on work remaining.
Auto-scroll: When enabled, the folder tree scrolls to highlight the folder containing the row you are editing.

Spreadsheet Editing

Direct cell editing: Click any cell in the New Filename, Tracking, Rev, Status, or Title columns to edit it. Press Enter to confirm, Escape to cancel.
RC References: Type a formula like =R[-1]C to copy the value from the cell one row above in the same column — similar to Excel relative references.
Regex capture groups: Type a formula like =RE(RC[-3], "(\w+)-(\d+)", "$1") to extract a pattern from another cell using a regular expression.
Validation: Cells are validated automatically. Invalid values are highlighted in red. The New Filename column shows the composed result.
Column Filters: Each column header has a filter input. Supported syntax:

term: Contains "term" (case-insensitive)
!term: Does not contain "term"
^term: Starts with "term"
term$: Ends with "term"
a b: Matches both (AND)
a | b: Matches either (OR)
^IFA | ^IFB: Starts with IFA or IFB
!^~: Does not start with ~ (excludes drafts)
el.*spc: Regex: contains "el" followed by "spc" (use . for any char, .* for any sequence)
[ei]fa: Regex character class: matches "efa" or "ifa"

Saving Files

Save All: Renames all modified files in one operation. Confirms before proceeding.
Cancel All: Reverts all unsaved edits back to the original filenames.
SHA256: Enable to compute a cryptographic hash of each file. Use Export Hashes to save a sha256sum-compatible file.

ZDDC Filename Format

The required format is:

TRACKINGNUMBER_REVISION (STATUS) - Title.ext

Example: 123456-EL-SPC-2623_A (IFR) - Electrical Specification.pdf
