xlsx 输出将保留工作表保护、可编辑区域、迷你图与图表；xls/csv/tsv 不支持这些特性。
批量转换如何工作
- 一次添加多个文件——xlsx、xls、csv、tsv 可以自由混选。
- 为整批文件选择目标格式。
- 点击转换；每个文件都在本地处理，完成后即下载。
什么时候需要批量转换
统一文件夹格式 — 把混杂着旧版 .xls 和 .csv 的文件夹统一转成现代的 .xlsx。
数据管道 — 把收到的 xlsx 附件转成 CSV，供只接受纯文本的系统使用。
一次性迁移 — 把整个存档在不同格式之间整体迁移，无需手工逐个打开文件。
Picking the right output format
- .xlsx — the modern default. Choose it to normalize mixed inputs (.xls, .csv, .tsv) into one up-to-date format that every current spreadsheet application opens natively.
- .xls — the legacy Excel 97-2003 format, kept for old ERP systems, accounting packages, and hardware that refuse anything newer.
- .csv — plain comma-separated text for databases, scripts, and web imports. Only the first sheet is exported, and all formatting is dropped.
- .tsv — tab-delimited text, handy when the data itself contains commas and you want to avoid quoting issues.
One-off conversions and related tools
This page is built for batches. If you only need one specific conversion, or a different kind of cleanup altogether, a dedicated tool is quicker:
- XLS to XLSX — upgrade a single legacy .xls file to the modern format.
- ODS to XLSX — convert OpenDocument spreadsheets coming from LibreOffice or OpenOffice.
- XLSX to CSV — export one sheet as CSV without running a batch job.
- Compress Excel — when the real goal is smaller files rather than a different format, shrink images and unused data instead.
- Analyze Excel data — profile a workbook's row counts, columns, and data types before deciding what to convert.
What is preserved during conversion
Cell values, dates, and number formats carry over to every output format. When the target is .xlsx, native sparklines are parsed from the source file and re-injected into the converted workbook, so in-cell charts keep rendering. Sheet protection settings are not carried into .xlsx output, so review sensitive files before sharing the results.
CSV and TSV are deliberately lossy: they keep only the values of the first sheet, with no formulas, styles, or additional tabs. Convert to .xlsx instead if you need the full workbook structure. Everything runs locally in your browser — files are converted in memory and delivered as one zip archive, never uploaded to a server.
常见问题
一次可以转换多少个文件？
免费用户每批最多 3 个文件；Pro 无限制。
转换时公式会重新计算吗？
在工作簿格式之间转换时，公式会作为公式保留；转换为 CSV 时写入的是最近一次计算的值。
转换后的文件保留原文件名吗？
保留——每个输出文件沿用原文件名，只更换扩展名。
Why does my converted CSV contain only one sheet?
CSV and TSV are single-table text formats with no concept of tabs. The converter exports the first sheet of each workbook; choose .xlsx output if you need every sheet preserved.
Is there a file size or batch limit?
Free users can convert up to three files at a time, each no larger than 10 MB. Upgrading removes both limits, subject only to your device's memory.
Will converting change my data?
Values, dates, and number formats survive the conversion. Formulas are kept when the target format supports them (.xlsx, .xls); plain-text formats store the last calculated results instead.
