AI Typing for Technical Specifications: Scanned PDFs to Editable DOCX

What a Technical Specification Sheet Contains

A typical optical ground wire (OPGW) or optical fiber cable specification sheet packs dense engineering data into several standard sections. You will see a cable construction table listing the number of fibres, stranding, and materials such as aluminium clad steel wires. Mechanical properties cover tensile strength, crush resistance, and bending radius. Electrical ratings include DC resistance, short circuit current rating, and lightning arc performance. Environmental properties specify operating temperature range and water blocking. The sheet almost always cites reference standards like IEC 60794 and IEEE 1138, and may include physical dimensions and weight. All these tables, units, and numerical thresholds must be typed exactly as they appear on the original scan.

Why Digitise Scanned Technical Specifications?

Scanned specification sheets are static image‑based PDFs that cannot be searched, copied, or edited without an intermediate typing step. Engineering and procurement teams digitise these for several practical reasons. When preparing tenders, you often need to extract values and tables from a manufacturer’s spec sheet and insert them into your own proposal document, a cut‑and‑paste task that demands an editable format. Design integration into CAD bills of material or line‑rating studies requires accurate data entry. Cross‑departmental sharing between procurement, design, and quality teams is far easier when the spec lives as a structured DOCX rather than a flat scan. Finally, long‑term digital archiving benefits from typed, machine‑searchable files that survive format obsolescence. In our experience typing similar documents, the primary driver is the need for a reliable, quickly reusable specification that the originator’s original soft copy is no longer available.

AI‑Powered Typing vs Manual Typing: What's the Difference?

Traditional typing services rely on human operators who retype every character and manually reconstruct tables, a process often measured in days and priced per word or page. Lekhak’s AI typing approach is fundamentally different. It automates optical character recognition with layout‑aware reconstruction, delivering an editable DOCX in minutes. The AI faithfully preserves table structures, numerical precision, and engineering units, though a brief review is always sensible for safety‑critical thresholds. For internal review, design reuse, and draft tender preparation, AI‑typed output is more than sufficient. For contractual tender submissions that expressly require a notarised true copy of the original specification sheet, you will need to go through a notary public or authorised officer, because a typed document, no matter how accurate, does not carry a notary’s certification. AI typing gives you the data; certification is a separate legal act you arrange independently.

What Lekhak's AI Typing Service Produces

Upload a scanned PDF spec sheet to Lekhak and you receive a single DOCX file in minutes. The output retains the original tables, all numerical values, symbols, and the logical structure of the specification sheet. There is no certification page, no notarisation, and no sworn statement attached, it is a pure, best‑effort digital reproduction. You can open the file in Microsoft Word or Google Docs and immediately edit, search, or copy data. The DOCX preserves the spec’s layout, including multi‑column cable construction tables and standard engineering units (kV, kA, mm², °C). Complex diagrams and line drawings are placed as non‑editable images inside the document. The service is self‑serve: you upload the scanned file, the AI types it, and the output lands in your account. No human retyping, no courier, no wait.

When You Need Notarised or Certified Copies for Tender Submission

Certain procurement processes, especially in the power and infrastructure sectors, demand that each technical specification sheet be submitted as a notarised true copy, a copy that a notary public or authorised officer has physically stamped and signed as a faithful reproduction of the original. Lekhak’s AI typing service produces an accurate typed version of the scan, but it does not supply any notarisation, apostille, or certified‑copy endorsement. If your tender documents state that notarised copies are mandatory, you must arrange this separately through a notary or the issuing authority. Lekhak does not offer or coordinate notarisation, and the typed DOCX should not be presented as a substitute for a formally certified true copy in such situations.

Standards Referenced in Technical Specifications

Most OPGW and optical fibre cable spec sheets cite IEC 60794 (optical fibre cables) and IEEE 1138 (testing and performance of OPGW). These are international benchmarks that define mechanical, electrical, and optical test methods. When Lekhak’s AI types a specification sheet, it reproduces these standard references exactly as they appear, including any edition years or amendment numbers. The presence of such citations tells reviewers that the cable has been designed and tested against a recognised framework. Lekhak’s service does not interpret or validate compliance; that assessment remains the engineer’s responsibility. The information is typed for reference and reuse, not as a substitute for a formal conformity declaration.

FAQ: AI Typing for Technical Documents

What file formats can I upload for typing?

You can upload scanned PDFs, images (JPG, PNG, WebP), existing DOCX, or TXT files. Clear, high‑resolution scans of printed specification sheets give the best accuracy.

Does the AI preserve tables, units, and numerical values accurately?

Yes. Lekhak’s typing engine detects table structures and recreates them in the output DOCX, preserving all numbers, units (kV, kA, mm², °C), and row‑column relationships. A quick review for any formatting quirks is recommended, particularly for dense cable‑construction tables.

How long does typing take?

Most specification sheets are processed in minutes. Unlike manual typing services that require days, Lekhak’s AI delivers the editable DOCX almost immediately after the upload completes.

Is the typed DOCX certified or notarised?

No. The output is a best‑effort AI‑typed document with no certification, notarisation, or sworn statement. If your tender demands a notarised true copy, you must arrange that separately.

What happens to my uploaded document after typing?

Your files are processed securely and deleted after conversion. Lekhak does not store or share technical specifications.

Can the AI capture handwritten notes on the scan?

Lekhak is optimised for printed text. Legible handwritten annotations are attempted, but accuracy may vary. For the best result, use clean originals without heavy markup.

Are diagrams and line drawings rendered as editable graphics?

No. Complex diagrams, schematics, and line drawings are placed as non‑editable images in the DOCX. The AI types the surrounding text and tables but does not vectorise or redraw technical illustrations.

Does the service handle equations and special engineering symbols?

Standard mathematical symbols, Greek letters (Ω, α, δ), and common engineering notation are reproduced reliably. For unusual or proprietary symbols, a minor manual correction step may be needed.

Can I use the typed DOCX directly in a tender submission?

The DOCX is an editable copy of the original spec. If the tender requires a notarised or certified true copy, you must obtain notarisation independently. Lekhak’s output does not carry any legal certification.

What if the original spec sheet is in a non‑English script?

Lekhak’s typing service works in 22 Indian languages and 70+ global languages. If your specification uses a non‑English script, the AI types it in the original language. For translation needs, Lekhak offers a separate AI translation service.
