OffcutBenchBY SMARTFACTFREE OFFCUT INVENTORY FOR ONE RACK
Updated
An offcut spreadsheet is a list of the reusable pieces on your racks, with each piece's material, size, location and date, that you check before buying or cutting new stock. OffcutBench keeps that list free in your browser for straight lengths on one rack: recording a cut or a use updates it, each piece gets a label and a length search, and the list downloads as a CSV whenever you want it in a spreadsheet.
Free to use. No account, email address or trial. Works offline once prepared.
At least the material, the size, where the piece is and when it went there, and for sheet offcuts the thickness, width and grain as well. OffcutBench handles straight lengths, one row per physical piece, so there is no quantity column. Its available pieces CSV has source_piece_key, material_code, length, length_unit, uncertainty, condition, batch, rack_code and bin_code. Each material code stands for its description, profile, grade, finish, colour and family, and the date each piece was recorded is in the history CSV.
If your materials and rack positions are already in a spreadsheet, save them as CSV and import them. The materials file has the columns material_code, description, profile, grade, finish, colour and family; the bins file has rack_code, bin_code, name, max_length, length_unit and material_families, where name repeats the rack name and families are separated by a pipe. OffcutBench previews the rows, keeps codes exactly as written, leading zeroes included, and adds all the rows or none. Templates for both files download from the import panel. Pieces are recorded one at a time, each measured and labelled.
A spreadsheet goes out of date the first time someone cuts a piece and forgets the row. In OffcutBench, recording the use is what changes the list: used whole takes the piece off, a cut takes it off and adds the remeasured remainder as a new piece with its own label, and scrap takes it off with a reason. Nothing is overwritten: each change is added to the piece's history.
Download the available pieces CSV whenever you need the list in a spreadsheet, and open it with the columns set to text so codes keep their leading zeroes. The history CSV has one row for every change, with the piece before and after, any cut, reason and job reference, and it adds an apostrophe before text a spreadsheet could treat as a formula. A rack list PDF prints the same available pieces.
A list is only as safe as its file. OffcutBench keeps the rack in this browser only when you choose Save on this device, and browser storage can be cleared, so download a backup too. The backup is one file with the rack, materials, bins, every piece and its full history. Importing it checks the whole file first, and an invalid file leaves the current rack untouched.
It is not a spreadsheet: it does not open .xlsx files, sync with a shared sheet or let several people edit one list. It keeps one rack of straight lengths, with no sheets, quantities, prices or purchasing, and it does not nest or optimise cuts.
For workshop owners, fabricators, joiners and makers who keep their offcuts in a spreadsheet, or mean to, and want the list to match the rack.
A USEFUL STARTING POINT
An offcut spreadsheet needs a row deleted for every piece used and a row added for every remainder, and nothing ties a row to the piece on the rack. OffcutBench keeps the same columns and links each record to a labelled piece: recording a cut takes the old piece off and adds the remainder, and the CSV downloads whenever you need it. It records what you tell it, so check the rack against the list now and then.
FROM QUESTION TO EVIDENCE
Import your materials and bins from CSV after a preview, or type them in, then measure and record each offcut on the rack with its own label.
When a piece is used, cut or scrapped, open it from a search or its label and record what happened. A kept remainder gets its own label.
Download the available pieces CSV or the history CSV whenever you need them in a spreadsheet, and keep a backup of the whole rack.
A joinery shop keeps its timber offcuts in a spreadsheet. Its materials, such as OAK-45 for 45 x 45 mm oak, import from CSV after a preview, and the offcuts are measured and labelled bin by bin. When a 1200 mm length of OAK-45 is cut into two 400 mm rails, the cut is recorded and the remainder is remeasured and labelled. The next available pieces CSV no longer lists the 1200 mm piece, and lists the remainder with its new identifier.
USED IN PRODUCTION
OffcutBench keeps one person's list for one rack. When several people cut from shared racks, RemnantRack keeps the offcut register for the whole team. It is in early access, with scope agreed at onboarding.
Early accessRemnantRack gives every reusable offcut a label, an exact length and a confirmed bin across your racks. Search for the length a job needs, reserve the piece so nobody else takes it, record the cut and label the remainder, with team access and a history for every piece.
BEFORE YOU START
Your materials and bins, yes, from CSV after a preview. The pieces themselves are recorded one at a time, because each one is measured and given its own label as it goes on the list.
Yes. Open it with the columns set to text, so codes and identifiers keep their leading zeroes. The available pieces CSV keeps exact values for importing into other systems; the history CSV adds an apostrophe before text a spreadsheet could treat as a formula.
Our page "How to keep track of offcuts" covers the routine: a length worth keeping, a label for each piece, a bin for every piece, a search before cutting new stock and a record of each use.
OffcutBench is one person's list for one rack of straight lengths, such as bar, tube, extrusion, profile or timber. There are no sheets or irregular shapes, no nesting or cutting optimisation, no reservations, no shared team stock and no saw control, and a search never reserves or changes a piece. Each search looks for one piece long enough for the whole job. A project holds one rack with up to 100 bins, 500 materials, 2,000 available pieces and 20,000 history records, in a saved file of at most 5 MiB. Lengths run from 1 mm to 60 m. The unit is fixed when the rack is created, and the usual measuring uncertainty is fixed once the first piece is recorded. CSV imports are up to 5 MiB, and one invalid row stops the whole import. The camera reads QR, Code 128, Data Matrix, EAN and UPC barcodes. Labels and reports show what you recorded, not proof that a piece is on the rack.
Your rack stays in this browser. Work starts in memory and is lost on refresh until you choose Save on this device or download a backup. Nothing you record, scan or download is uploaded, and camera images are decoded on your device and never stored. No account or contact details are needed. Google Analytics is optional and loads only after you accept; it never receives materials, lengths, label codes, job references or file contents. Use Analytics settings on these pages or in the tool to change your choice; see /privacy/.
