Excel 转 PDF——本地两步成档，多 sheet 连续排版Excel to PDF locally — two steps, every sheet in order
先说最容易踩的那格：Excel 里看到的"表格"，在文件里其实是三类东西的叠加——单元格的值、公式、以及格式（列宽、颜色、合并、条件格式）。这条链能带走第一类，第二类带的是缓存结果而不是活公式，第三类基本带不走。所以产物是一张干净、可打印、可复制文字的表格文档，而不是"你那张带底纹的报表"。知道边界之后再决定用它还是用 Excel 自己导出。Start with the trap, because it is the one people hit: the "table" you see in Excel is three things stacked — cell values, formulas, and formatting (column widths, colours, merges, conditional rules). This chain carries the first, carries the second as its cached result rather than as a live formula, and carries almost none of the third. So the output is a clean, printable, copyable table document, not *your* shaded report. Knowing that boundary is what makes the choice between this and Excel’s own export an informed one.
这条链路怎么走How the route runs
Excel (.xlsx)Excel (.xlsx) HTMLHTML PDFPDF
共 2 步，由扩展的路径搜索自动选出，中间产物不落盘。2 steps, chosen by the extension's own path search; intermediate results never touch the disk.
会保留什么What carries over
- 每个工作表一张表格；多于一个 sheet 时，每张前面带上它的名字作为标题，PDF 里就是 `<h2>` 一级的分节One table per worksheet; when the workbook holds more than one sheet, each is preceded by its own name as a section heading
- 单元格值按显示文本写入：日期单元格在阅读阶段就被显式标记并按统一格式渲染，不会变成 45296.33 这样的序列号Cell values are written as display text: date cells are flagged while the workbook is read and rendered under one agreed format, so 45296.33 never appears where a date belongs
- 文本、数字与布尔的原样字符——这条链默认以"值保真"为目标，不替你四舍五入Text, numbers and booleans keep their own characters — this chain aims at value fidelity and does not round on your behalf
- 文字进 PDF 是真的文字层，可选中、可复制、可搜索（这与"表格截图"不同）Text in the PDF is a real text layer: selectable, copyable and searchable, unlike a screenshot of a spreadsheet
- 中间那份 HTML 只在内存里，你的下载目录只多出一个 .pdfThe intermediate HTML exists only in memory, so your downloads gain one .pdf and nothing else
如实说明的限制What it does not do
- 格式不进产物：字体、颜色、底纹、列宽行高、边框样式、条件格式、数字自定义格式都不参与，PDF 里是统一的表格样式Formatting does not travel: fonts, colours, shading, column widths and row heights, border styles, conditional rules and custom number formats are all absent, and the PDF shows one shared table style
- 合并单元格不还原成跨行跨列，只是把值放在左上那一格Merged cells are not reproduced as spans — the value sits in the top-left cell
- 公式不求值：格子里是文件上次保存时算好的值；从没保存过或依赖外部数据时可能为空Formulas are not evaluated: each cell holds whatever the file last cached when it was saved, which can be blank for unsaved or externally-fed workbooks
- 图表、数据透视表、切片器、批注、宏、图片与形状都不提取Charts, pivot tables, slicers, comments, macros, embedded pictures and shapes are not extracted
- 分页位置由内容高度决定（A4 竖版按高度切），不能指定纸张、方向、缩放或打印区域；超宽表格会被排到下一页而不是缩小塞进一页Page breaks follow content height (portrait A4, sliced by height); paper size, orientation, scaling and print areas cannot be set, so a very wide table spills to the next page rather than shrinking to fit
- 只读 .xlsx（zip 包），旧版 .xls / .et 等格式不在识别范围内Only the zipped .xlsx package is read; legacy .xls and similar spreadsheets are outside detection
实操提示Working with it
- 同一份 .xlsx 还能转 CSV、JSON、Markdown、HTML 与 PNG：前四种保留值、丢格式，PNG 则是整页像素The same .xlsx can also go to CSV, JSON, Markdown, HTML and PNG: the first four keep values and drop formatting, while PNG is page-by-page pixels
- 多 sheet 的 CSV 会输出 ZIP（一个 sheet 一个文件），而这条 PDF 路径是把所有 sheet 串进同一份文档——两种形态各有用处A multi-sheet workbook becomes a ZIP for CSV, one file per sheet, whereas this PDF route strings every sheet into one document — the two shapes serve different jobs
- 单个上限 100 MB，一批最多 200 个文件；链路较长，超大工作表建议先只留必要列再转100 MB per file and up to 200 files per batch; it is a long chain, so trim a very large worksheet to its needed columns first
常见问题Questions people actually ask
为什么 PDF 里的表格没有我原来的底色？Why did my shading not make it into the PDF?
因为这条链取的是单元格的值，样式层在 HTML 那一步就没有参与。要带底纹的报表，用 Excel 自己导出 PDF；这里的定位是"把数据变成可分发、可复制文字的文档"。Because the chain reads cell values, and the style layer never takes part once the content is in HTML. For a shaded report, let Excel export the PDF; this route’s job is turning data into a distributable document whose text is selectable.
日期那一列变成了 45296 怎么办？What if the date column turns into 45296?
这条路径不会：日期单元格在读取时被显式标记，并按统一的文本格式渲染，所以到 PDF 里仍然是日期文本。真看到序列号，通常说明那格在源文件里本来就是数字而不是日期格式——回到 Excel 里把该列设成日期格式再转一次。It does not here: date cells are flagged during the read and rendered through one agreed text format, so the PDF still says a date. If a serial number does appear, that cell was most likely a plain number rather than a formatted date in the source — set the column to a date format in Excel and convert again.
宽表格被切到第二页，能强制一页放下吗？A wide table spilled on to a second page — can I force it on to one?
不能，这条没有纸张、方向、缩放或"适应页面"的参数。可行的办法是在源文件里删到必要列、或改走 Excel → HTML 自己控制宽度，再 HTML → PDF。No — there is no paper, orientation, scaling or fit-to-page parameter on this route. What works is dropping to the columns you need, or taking Excel to HTML and controlling width there before going HTML to PDF.
不需要账号，也不需要联网：装好扩展后点图标，在新标签页里打开工作台，文件从磁盘直接选。No account and no network: install the extension, click its icon, and the workbench opens in a new tab reading straight off your disk.
