vibe coding 了个不上传文件的 CSV 工具箱,想找一些奇怪 CSV 来测试 最近做了一个 CSV 工具站:CSV Dock 。 网站: https://csvdock.com 做它的起因是自己处理 CSV 时经常遇到几个问题: - 不太愿意把包含业务数据的 CSV 上传到陌生服务器 - Excel 打开 CSV 时容易出现乱码、分列错误或丢失编号前面的 0 - 文件稍微大一点,很多在线工具就会卡死 - CSV 、JSON 、Excel 转换通常散落在不同网站,操作方式也不统一 所以我做成了一个 local-first 的工具箱:文件直接在浏览器内处理,不上传到应用服务器,也不需要注册账号。 目前包含: - CSV 查看、搜索和排序 - CSV 转 Excel ( XLSX / XLS ) - Excel 转 CSV ,可将全部工作表导出为 ZIP - JSON 转 CSV ,支持选择数组路径和展开嵌套对象 - CSV 转 JSON / JSON Lines - 多个 CSV 按表头或列位置合并 - CSV 结构检查,

做了个 PDF 银行流水转 CSV 的站,重点是「哪里没读出来会告诉你」 这是一个 [bank statement converter]( https://getbankcsv.com/):把 PDF 银行对账单转成 CSV / Excel / QIF / OFX / QBO 。这个品类工具不少,我做的时候盯的是两个一直没被解决的问题。 ## 一、转出来的文件导不进会计软件 这跟提取质量无关,卡的是列名、日期格式、文件大小这些事。Intuit 自己的文档写得很明确: QuickBooks 收的 CSV 必须是英文、不超过 350 KB 、单次最多 1000 行、只能是三列 ( Date, Description, Amount )或者四列。一年的活期账单,后两条都会超。 所以我按 QuickBooks 和 Xero 各自文档要的形状分别出文件,而不是给一个通用 CSV 让你自己改。 ## 二、漏读了,但没人告诉你 这个更要命。版面解析或者 OCR 漏掉一整块交易,输出看起来完全正常,你导进账里, 几个月后对账才发现少了一截。 我这边的做法:
