Convert an engineering drawing to Excel: questions and answers

The questions people actually ask before uploading a drawing.

Can I convert a PDF drawing to Excel for free?

Yes. Drop the PDF on the home page and the extracted rows come back as a table you can export to .xlsx. No account and no card. The free allowance is 5 uploads per day per IP address; browsing the site is never rate limited.

Do I need to sign up or give an email address?

No. There is no account, no login and no email wall. You only see an email box if you go over the daily allowance, and leaving it there is optional — it does not unlock anything and we do not send you mail.

What file types does it read?

PDF, PNG, JPG, TIFF, BMP and WEBP for 2D drawings, plus STEP and STP for 3D models. Multi-page PDFs are read up to 10 pages per file.

Can it read a DWG or DXF file?

Not directly. Export a PDF from your CAD program and upload that instead — vector PDFs exported from CAD are the cleanest input this tool gets.

Can it extract a bill of materials from a PDF drawing?

Yes, when the drawing carries a parts-list table: each row of that table becomes a row in the Excel output, with the columns you defined.

How do I get a STEP file into an Excel BOM?

Upload the .step or .stp file. Bounding box, face count and solid count are computed from the geometry itself — no vision model reads your model. The file and its geometry never leave our server; the only thing sent to a language model is your list of column names, so it can match them onto the quantities we computed. Anything a 3D model cannot carry (material grade, surface finish, weight) is left blank and marked rather than guessed.

How accurate is it?

It varies by drawing, which is why the honest answer is in the interface rather than a number on a landing page. Every value that fails a deterministic check is filled in and turned red with a reason, and the red flag follows the value into the exported Excel. Treat the output as a first pass to review, not as a finished document.

Does it extract GD&T or geometric tolerances?

No. Feature control frames, datums and geometric tolerances are not parsed. We would rather say so than sell you a keyword we cannot back.

Can I upload a whole folder of drawings at once?

Up to 30 files per batch, 2 running at a time, with per-file progress. The daily free allowance counts each file, so a batch of five uses the whole day.

What happens to my drawing after the extraction?

It is never written to a disk on our server. The bytes stay in memory for the seconds the extraction takes and are then dropped. We keep one row of usage numbers per file (type, size, seconds, token count, success or failure) and nothing from inside the drawing itself.

Can I change which columns come out?

That is the main control on the page. Add, rename or delete columns, and write your own sentence under each one telling the AI what to look for. Your wording goes into the instruction verbatim — there is a button that shows you the exact text that gets sent.

Is there an API?

Not yet. Today it is a web page you drop files onto.
