How to Auto-Build a Spreadsheet with ChatGPT

Manually building engineering spreadsheets? That ends today. Here's a smarter, faster way to auto-generate a complete Reynolds Number table—formulas, units, references, and all—using ChatGPT.

This method turns a single prompt into a fully formatted spreadsheet. It’s fast, clean, and repeatable. Benefits include:

• Instant table structure: description, symbols, units, and references aligned

• Pre-loaded formulas like Reynolds Number — no setup needed

• Works across disciplines (you can reuse this format for NPSH, pressure drops, etc.)

• Saves 30–60 minutes per spreadsheet

By using GPT-4o Mini, engineers skip the grunt work and focus on validation, not formatting.

Like any AI output, this method has limitations:

• It needs very clear prompts — ambiguity causes errors

• It won’t understand context unless you define every column

• The first output might need tweaks for formatting or units

Despite that, it's a perfect fit for Singularity’s AI-first workflow. This tactic automates routine documentation so engineers can move 10x faster in building calculation templates.

We’ve tested this across multiple client requests. It saves hours and builds trust. Next time you need a Reynolds number sheet—prompt it.
