A worksheet is not always just a grid of numbers. Sometimes it is a canvas — a flowchart sketched between data blocks, a relationship diagram connecting teams to projects, a callout pointing from a note to the cell it annotates. In every one of these cases the missing element is a line: a straight stroke between two boxes, a curved arc around a region, an elbow connector that bends once and continues.
Clearer Excel Charts in JavaScript: Multi-Level Labels & Dual Axes
2026-09-23 07:30:28
A column chart with regions and months on the same axis has two problems, and they are not the same problem. The first is that the category labels collapse into a single row — "North", "Jan", "North", "Feb" — and the reader has to mentally re-group which month belongs to which region. The second is that when a growth-rate series is added alongside a sales series that runs into the millions, the growth rate becomes a flat line hugging the baseline, because one value axis cannot serve two magnitudes at once.

When an Excel worksheet contains hundreds of rows, scrolling through raw data makes reports difficult to read.

Depending on how your data is structured, you can group rows manually, use automatic tools, or apply grouping in PivotTables.
AI Document Generation: From Data to Ready-to-Use Documents
2026-09-20 02:37:22
AI document generation uses natural-language instructions, source data, and templates to create structured Word, Excel, PowerPoint, and PDF files — not just text, but formatted documents with sections, tables, charts, and styling. Unlike simple AI text generation, it produces complete, ready-to-use files that comply with Office formatting standards. This article covers what AI document generation is, how it works, online tools you can try right now, and a C# implementation with [Spire.Agent.Office](/introduce/spire-agent-office.html).
Reducing PDF File Size: Images, Fonts & Content Streams in JavaScript (React)
2026-09-18 08:16:08
A PDF is rarely just "too big". It is too big for one specific door — a mail attachment cap, an upload form, a storage quota — and whatever pushed it past that limit is usually one of three things. Compressing without knowing which one means guessing, and guessing costs either quality or another failed upload.
Reading and Extracting Excel Formulas in JavaScript (React)

Somebody built this workbook years ago. It recalculates when the data changes, the totals move in ways nobody predicts any more, and there is no documentation — because the formulas are the documentation. Reading the numbers will not tell you how they were produced. Reading the rules will.
