ZDDC Classifier

This standalone tool is being absorbed into the Browse app. Browse's Grid view-mode now provides the same spreadsheet workflow alongside file navigation. This standalone build remains available for offline use and air-gapped environments.

Rename a folder of files to ZDDC format using a spreadsheet interface.

Open a directory, fill in tracking number, revision, status, and title for each file, then save — the files are renamed on disk.

Files already named to ZDDC format are parsed automatically
Edit cells directly, or copy columns to and from Excel
Real-time validation highlights non-compliant names
Rename one file or all modified files at once

Click Use Local Directory to begin.

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, ---
