Folder Tree

Auto-scroll Hide Compliant

Give each file a tracking number (revision + status + title) under By tracking number — that alone is a Rename in place. Route it into a transmittal folder under By transmittal to Copy it into the archive.

Drag files in (ctrl-shift-click the left tree to multi-select; drop on a row to fill a contiguous block), or “Add filtered files”. Type the tracking number, revision (“A (IFR)”) and title — already-ZDDC-named files fill in. “Load…” / “Paste rows…” add rows to drop files onto.

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.

Classify, then Rename or Copy

Give each file a ZDDC name in the By tracking number grid. A tracking number alone is a rename; add a transmittal folder and it can be copied into the archive.

New workspace → pick a folder. It scans once and saves to this browser, so you can close the tab and pick up later.
Add files to the grid — drag them from the left tree (ctrl-shift-click to multi-select and fill a block of rows), use ⊕ Add filtered files, or ⊞ Load… / ⎘ Paste rows… a list of expected tracking numbers and drop the matching files on. Already-ZDDC-named files fill in automatically.
Type each file's tracking number, revision (e.g. A (IFR)) and title.
Rename… (By tracking number) renames the named files in place on disk — destructive, no backup. Or place them into a transmittal under By transmittal and Copy… them into the archive (source untouched, resumable, verified).

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

Valid statuses: IFA, IFB, IFC, IFD, IFI, IFP, IFR, IFU, REC, RSA, RSB, RSC, RSD, RSI, ---
