Excel
A spreadsheet application included in the Microsoft Office suite, widely used for data analysis, financial calculation, and report generation. It is one of the most widely adopted office productivity applications globally.
Core Facts
WorkBuddy can handle scenarios such as file management (batch categorization, batch renaming, multi-document information aggregation), document data processing (weekly report generation, Excel spreadsheet operations), website development, collaborative office work, and periodic tasks.
Commonly used Python office automation libraries include openpyxl for handling Excel, python-docx for handling Word, and PyPDF2 for handling PDF
Excel's 1900 date system contains a legacy bug that incorrectly recognizes February 29, 1900 as a leap day, and this bug is intentionally retained for backward compatibility.
Timeline (last 90 days)
The choice of structured data output format should match the downstream use: JSON is more suitable for consumption by front-end applications, while CSV or Excel is more direct for data analysts to use.
PDF to Word facilitates editing text, PDF to Excel facilitates handling tables, PDF to JPG can turn document pages into image files, JPG to PDF is used to merge multiple images into a single document, and Word to PDF is suitable for sharing documents in a uniform format.
The human-readable date displayed in a cell is determined by that cell's number format string; reading the raw value directly from XML will only yield the serial number.
Serial number 45366.5 represents noon on March 15, 2024.
The 1904 date system originated from a design choice in the early Macintosh version of Excel, because Mac hardware could not represent dates before 1900, so engineers set the starting epoch to January 1, 1904.
A cell with a value of 0.0833 and a format of [h]:mm is actually displayed as 2:00, representing a duration.
A spreadsheet is a display format disguised as a data format; the file itself stores only numbers and format strings.
The basis for judging the semantics of cell data should be the semantic intent carried by the format string, not the numeric value itself.
Excel inherited a leap year bug from Lotus 1-2-3: dates with serial numbers less than 60 are off by one day compared to the actual date.
SimpleSpread is not a comprehensive replacement for Excel or Numbers and does not include heavy features such as complex pivot tables, chart visualization, or collaborative sharing.
