The Short Answer
Excel is a calculation tool; it was never a field documentation system. Spreadsheets can hold grade shots, but they can't capture GPS and timestamps automatically, compare shots against design grade, work offline in a trench, or produce an as-built PDF an inspector accepts. The practical cost of a spreadsheet workflow is nightly re-entry, transcription errors, and documentation that doesn't hold up in a dispute. Excel stays great for office-side analysis — Gradelog replaces it in the field.
The typical spreadsheet workflow on a dirt job looks like this: the grade checker writes shots in a field book, the foreman photographs the page or retypes it into a phone, someone retypes it again into Excel that night, and the office reformats it into something presentable. Every handoff is a chance for a transposed digit — and a transposed elevation is exactly the kind of error that surfaces weeks later as a rejected submittal or a quantity dispute.
A purpose-built field tool removes the handoffs entirely: the shot is logged once, on the spot, with GPS, timestamp, and design comparison attached, and the report generates itself. The 30–60 minutes a foreman spends retyping every night goes back to running the crew.
No pass/fail against design grade at the moment the shot is taken — you find out you're out of tolerance after the fact. No GPS or automatic timestamps, so every row is only as trustworthy as the person who typed it. No offline field capture with sync. No calibration records tied to the instrument that took the shot. And no defensible chain of documentation: an Excel file can be edited by anyone at any time, which is precisely what opposing counsel will point out in a quantity or grade dispute.

Bid worksheets, one-off volume calcs, office-side analysis of exported data, anything that never leaves your desk — keep using Excel. It's excellent at those jobs, and Gradelog exports CSV specifically so that office workflows keep working. The line is simple: if the data is born in the field and has to survive an inspector, a dispute, or a second person retyping it, it shouldn't live in a spreadsheet.
Yes. Gradelog exports clean CSV of your grade shots, quantities, and timecards, so anything your office already does in Excel keeps working. The difference is the field data arrives structured, GPS-tagged, and typo-free instead of being retyped from paper or a truck-cab spreadsheet.
The typical pattern is: shots written in a field book or phone notes, retyped into Excel at night, reformatted into a report, then emailed. That is 30–60 minutes per day of re-entry per foreman, plus transcription errors that surface as rejected submittals or quantity disputes — each of which can cost far more than a software subscription.
Excel is fine for one-off calculations, office-side analysis, bid worksheets, and anything that never has to survive an inspector, a dispute, or a second person retyping it. It stops being fine when field data needs GPS context, timestamps, design-grade comparison, or an inspector-ready PDF.
Gradelog imports CSV exports from Topcon MAGNET Field, Trimble Access, Leica Captivate, and Spectra instruments, and its data tools accept standard CSV — so existing shot data can be brought in rather than retyped.
