【问题标题】：Skip 6 rows before "reading" into powerquery在“读取”到电源查询之前跳过 6 行
【发布时间】：2016-09-16 15:34:39
【问题描述】：

我正在尝试自动化一些基于 Netsuite（我们的 ERP 软件）导出的 CSV 的报告。这些文件永远不会正确直接导入 PowerQuery，因为有 6 行是“标题”行。这些标题行没有正确数量的逗号，因此 PowerQuery 仅显示 1 列数据。我目前正在使用 Notepad++ 打开文件并删除这 6 行，然后将文件导入 PowerQuery。

有没有办法使用 PowerQuery 代码跳过前 6 行，以便正确读取 csv？以下是我正在处理的数据示例。

【解决方案1】：

使用原生 CSV PowerQuery 解析器

let
    file_path = "C:\your_path\csv.txt",
    file = File.Contents(file_path),
    src = Lines.FromBinary(file),
    skip = List.Skip(src,6),
    combine = Text.Combine(skip, "#(lf)"),
    csv = Csv.Document(combine),
    promote = Table.PromoteHeaders(csv)
in
    promote

【解决方案2】：

table.skip可以为所欲为

第二个参数可以是数字（例如6）或条件（例如(#"Position of ""Options: Show ZerosFilters: Customer/Project (equal to FCC - Hotel Hotel ), Validated Status (not equal to Cancelled, Closed )""" + 1)）

感谢您的提示 - 知道一个人也可以通过条件非常有用！在这里为我工作的代码是：Table.Skip(Source, List.PositionOf(Source[Column1], """Options: Show ZerosFilters: Customer/Project (equal to FCC - Hotel Hotel), Validated Status (not equal to已取消，已关闭 )""") + 1)。首先将所有数据读入名为“Column1”的列中。转义 " 有点特别。

【解决方案3】：

问题是您尝试在 Power Query 中“从 CSV”导入 CSV 作为源。具有描述内容的第一行将破坏自动转换。因此，为了防止这种情况，您必须以另一种方式将文件导入 PQ。 Ken 的Excelguru Blog 很好地描述了这个问题（顺便说一句：我热烈推荐他的书）。

代码如下：

let
    /* Get the raw line by line contents of the file, preventing PQ from interpreting it */
    fnRawFileContents = (fullpath as text) as table =>
    let
        Value = Table.FromList(Lines.FromBinary(File.Contents(fullpath)),Splitter.SplitByNothing())
    in Value,

    /* Use function to load file contents */
    Source = fnRawFileContents("D:\yourfile.csv"),
    #"Removed Top Rows" = Table.Skip(Source,6),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Removed Top Rows","Column1",Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv),{"Column1.1", "Column1.2", "Column1.3", "Column1.4", "Column1.5", "Column1.6", "Column1.7", "Column1.8"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Column1.1", type text}, {"Column1.2", type text}, {"Column1.3", type text}, {"Column1.4", type text}, {"Column1.5", type text}, {"Column1.6", type text}, {"Column1.7", type text}, {"Column1.8", type text}}),
    #"Promoted Headers" = Table.PromoteHeaders(#"Changed Type")

in
    #"Promoted Headers"
