OpenXML does not help to read large Excel files contrary to documentation

由 a 夏天 提交于 2019-12-04 05:29:00
问题 The documentation says that: The following code segment is used to read a very large Excel file using the DOM approach. and then goes an example. I use it to implement reading a relatively large file with 700K rows. I have this code by now: using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(path, false)) { WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart; WorksheetPart worksheetPart = workbookPart.WorksheetParts.First(); SheetData sheetData = worksheetPart

Set Rows to repeat at top when printing - Open XML and Excel

由 不想你离开。 提交于 2019-12-04 04:19:18
问题 I am trying to get the first 4 rows of an xlsx file to repeat at the top of each page when printed. I am using the Open XML SDK to accomplish this. My file is being generated by the SSRS execution web service as a filestream. I then need to modify several layout and page settings (margins, page size, zoom, etc) before delivering the file to the user, as my users have very little Excel acumen. All other settings I need to tweak are working correctly, so I have stripped out all of that code

What's the difference between <c t=“str”> and <c><is> in Office Open XML?

由 喜你入骨 提交于 2019-12-04 03:11:29
问题 What's the difference between these two Office Open XML fragments? <c r="A2" t="str"> <v>btyler</v> </c> and <c r="B2"> <is><t>btyler</t></is> </c> note: The second sample I created manually based on the spec, the first is from an actual Excel workbook. Both seem valid and pretty much identical according to the spec, so I'm wondering why there is t="str" when <is> seemingly does the same thing. When does Excel choose to use one over the other? 回答1: According to the documentation at 18.18.11

Embed contents of a RTF file into a DOCX file using OpenXML SDK

由 陌路散爱 提交于 2019-12-04 01:38:59
In our old MSWord-97 based system we use COM to interact with a .doc file, and embed an OLE object, so the embedded document is visible in the parent (not as an icon). We're replacing this with a system using OpenXML SDK since it requires having Word on our server, which generates .docx files. however we still need to embed the contents of RTF files into the generated DOCX... specifically we replace a bookmark with the contents of the file. I found a few examples online but they all differ. When I create a simple example in Word and view the XML, there's a lot of stuff to position/display the

How to insert a date to an Open XML worksheet?

由 别说谁变了你拦得住时间么 提交于 2019-12-04 00:21:29
I'm using Microsoft Open XML SDK 2 and I'm having a really hard time inserting a date into a cell. I can insert numbers without a problem by setting Cell.DataType = CellValues.Number , but when I do the same with a date ( Cell.DataType = CellValues.Date ) Excel 2010 crashes (2007 too). I tried setting the Cell.Text value to many date formats as well as Excel's date/numeric format to no avail. I also tried to use styles, removing the type attribute, plus many other pizzas I threw at the wall… Can anyone point me to an example inserting a date to a worksheet? Andrew J You have to convert
