02 / A spreadsheet idea, made interactive

Keep a weather record.
See the pattern.

Enter observations, browse the table and chart a city's temperatures. Reconstructed from the navigation, data entry and charting design of my earlier Excel project.

This is a new browser implementation, not the original Excel file or proof of a completed VBA system. Records stay in this browser. Export a CSV for Excel or as a backup. The example rows are invented demonstration data, not measured weather.

Add an observation

Temperature over time

Each point is one record. The line connects entries in date order; it does not imply a continuous measurement. Sample rows are included when present.

Your log is empty. Add an observation or load clearly marked sample rows to explore the chart.

The original Excel idea

A main menu would lead to input, historical records, and database/statistics worksheets. Buttons and a consistent layout were intended to make the workbook easier to navigate. VBA automation was explored; the final use of VBA is unconfirmed.

What this version adds

A working form, edits and deletion, a city chart, local storage and CSV export. No weather service is connected, so the application never presents sample entries as live conditions.
