We are using "Syncfusion.XlsIO.Base" 15.4460.0.20, we are trying to copy worksheet of one excel file into another excel file. But while copying the file, it is throwing Stack OverFlow exception.
Below is our code
using (ExcelEngine excelEngine = new ExcelEngine())
{
//Open an existing workbook.
IWorkbook workbookMonthly = null;
workbookMonthly = excelEngine.Excel.Workbooks.Open(monthlyReport);
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2013;
IWorkbook reportWorkbook = application.Workbooks.Create();
reportWorkbook.Version = ExcelVersion.Excel2013;
for (int i = 0; i <= 1; i++)
{ reportWorkbook.Worksheets.AddCopy(workbookMonthly.Worksheets[i],ExcelWorksheetCopyFlags.CopyAll);
}
The issue is raised based on the worksheet data in your source document. So, it will be more easier to analyze, if you could share the below information
Total rows and columns used in the worksheet including blank cells
with formatting.
The type of data in the source workbook such as conditional
formatting, named range, formulas, table, pictures and so on.
The stack trace of the exception.

I have a dataframe var cache :DataFrame = _. As an initial run i have given, cache = existingDF, the existingdf is read from an excel using crealytics.spark.excel.
but in the subsequent run, the existingDF will get another updated excel file, it should be cache = cache.union(existingDF)
But I seem to get only existingDF inside cache. In short whenever i call cache it seems to read the excel. How do i avoid this? This issue is not there while reading it as csv. (It was there when i used .persist on the csv read, but got fixed when i removed .persist
More Simply:
var a = _
while(true){
val b = spark.read.format("com.crealytics.spark.excel")...
if (Option(a).isEmpty){
a = b
}
else if a!=b
a = b.union(a)
}
The variable a is always getting updated along with b, so it never becomes different from b. How do I avoid this?
I have a program which exports a System.Data.DataTable to an XLSX / OpenXml Spreadsheet. Finally have it mostly working. However when opening the Spreadsheet in Excel, Excel complains about the file being invalid, and needing repair, giving this message...
We found a problem with some content in . Do you want us to
try to recover as much as we can? If you trust the source of the
workbook, clik Yes.
If I click Yes, it comes back with this message...
Clicking the log file and opening that, just shows this...
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">

Obviously, we don't want to deploy this into a production environment like this. So I've been trying to figure out how to fix this. I threw together a quick little sample to validate the XML and show the errors, based on this link from MSDN. But when I run the program and load the exact same XLSX document that Excel complains about, the Validator comes back saying that the file is perfectly Valid. So I'm not sure where else to go from there.
Any better tools for trying to validate my XLSX XML? Following is the complete code I'm using to generate the XLSX file. (Yes, it's in VB.NET, it's a legacy app.)
If I comment out the line in the For Each dr As DataRow loop, then the XLSX file opens fine in Excel, (just without any data). So it's something with the individual cells, but I'm not really DOING much with them. Setting a value and data type, and that's it.
I also tried replacing the For Each loop in ConstructDataRow with the following, but it still outputs the same "bad" XML...
rv.Append(
(From dc In dr.Table.Columns
Select ConstructCell(
NVL(dr(dc.Ordinal), String.Empty),
MapSystemTypeToCellType(dc.DataType)
)
).ToArray()
)
Also tried replacing the call to Append with AppendChild for each cell too, but that didn't help either.
The zipped up XLSX file (erroring, with dummy data) is available here:

For anyone else coming in and finding this, I finally tracked this down to the Cell.DataType
Setting a value of CellValues.Date will cause Excel to want to "fix" the document.
(apparently for dates, the DataType should be NULL, and Date was only used in Office 2010).
Also, if you specify a DataType of CellValues.Boolean, then the CellValue needs to be either 0 or 1. "true" / "false" will also cause Excel to want to "fix" your spreadsheet.
Also, Microsoft has a better validator tool already built for download here:

I am trying to export the ag-grid data to CSV.
The issue is, it exports only the visible data OR the in-memory data received from HTTP call while considering paginationPageSize, maxBlocksInCache, cacheBlockSize etc. in the grid. Not the entire data-set.
I went through below links, but couldn't get much help.
[export] Export to CSV all pages in Client side
Pagination
agGrid
data
export
Is there any way we can achieve this? Or this is altogether not possible?
This is how i solved this -
fetch all rows you need from your data source
clone gridapi object
grab the serverside cache from the cloned gridapi
process it so its filled with your feched data
run export to excel method on the cloned gridapi
...
PROFIT
const gapi = cloneDeep(this.gridApi); // clone gridApi
const blocks = gapi['serverSideRowModel'].rootNode.childrenCache.blocks; // object notation to suppress private warning/err
// swap rows cache with fetched data
for (let i = 0, j = 0; i < Math.ceil(results.length/this.paginationPageSize); i++) {
// we alter relevant block, or if it is not loaded yet we clone 1st one and alter it
const block = blocks[i] || cloneDeep(blocks[0]);
block.rowNodes.forEach(n => n.data = results[j++]);
blocks[i] = block;
}
gapi['serverSideRowModel'].rootNode.childrenCache.blocks = blocks;
gapi.exportDataAsExcel(params);
I'm new to stackexchange so my apologies if this question is too extensive or already answered somewhere I couldn't find. You can find the spreadsheet here, the script here and the dashboard (dev version) here.
I have been banging my head on handling dates in the google app script visualization for days.
My ultimate goal is to make a dashboard that includes an annotated timeline as well as other charts based on a data set in a spreadsheet. I have started this process using Mogsdad tutorial on creating a 3-tier google visualization dashboard, where the data is pulled from external spreadsheet and then pulled into the DataTable using arrayToDataTable. Everything worked great out of the box. However, my data contains dates, so I added a date column to the original data, but alas arrayToDataTable doesn't accept date type per this post. So when a Date column is added i get the following result:
ScriptError: The script completed but the returned value is not a
supported return type.
I have tried multiple approaches to ensure even date formatting: options includes putting the values in the date column through new Date(dateColumn[i]), dateColumn[i].toJSON() (renders the dash board, but dates aren't able to be processed), forced date formats in the spreadsheet (yyyy-MM-dd), using the DataView outlined in the post above (dashboards don't get past 'Loading'), and such.
So my question is what is the alternatives to arrayToDataTable that will accept date columns in this 3-tier approach? Or alternatively, what are the errors in the below methods?
For all the cases when I have attempted to add columns I have changed the code from var data = google.visualization.arrayToDataTable(response,false) to var data = google.visualization.DataTable()
I have tried the following:
Manually adding columns and manually adding data (not working)
//Add Columns
data.addColumn('string','Name');
data.addColumn('string','Gender');
data.addColumn('number','Age');
data.addColumn('number','Donuts eaten');
data.addColumn('date','Last Donut Eaten');
//Add Rows
data.addRows([
['Miranda','Female', 22,6,6],
['Jessica','Female',22,6,12],
['Aaron','Male',3,1,13]
]);
Automatically adding the rows without dates (The rows are added, but it only works if there are no date columns)
//Add Rows
for (var i=1; i<response.length; i++) {
data.addRow(response[i]);
}
Manually adding columns and automatically adding rows (not working, combination of 1 and 2)
Automatically adding the columns with loops (not working, neither if dates or not)
for (var i=0; i<response[0].length; i++) {
if (response[1][i] instanceof Date) { //Checks if first value is Date
data.addColumn('date',response[0][i]);
};
else if (response[1][i] instanceof Number) //Checks if first value is Number
data.addColum('number',response[0][i]);
else data.addColumn('string',response[0][i]; //Otherwise assume string
};
Thank you so much for your help!
you can use the Query (google.visualization.Query) class to pull the data from the spreadsheet,
this will convert the date column properly...
google.charts.load('current', {
packages:['table']
}).then(function () {
var queryURL = 'https://docs.google.com/spreadsheets/d/1aaxYNLCuPz3o3TA1jdryenUP01Qbkdaut4AR5eIhe9s/edit#gid=0';
var query = new google.visualization.Query(queryURL).send(function (response) {
var data = response.getDataTable();
// show column types
for (var i = 0; i < data.getNumberOfColumns(); i++) {
console.log(data.getColumnLabel(i), '=', data.getColumnType(i));
}
// draw table chart
var table = new google.visualization.Table(document.getElementById('chart-table'));
table.draw(data);
});
});
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="chart-table"></div>
note: the example uses jsapi to load the library,
this library should no longer be used.
according to the release notes...
The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader.js from now on.
this will only change the load statement, see above snippet...
I have a custom template in which I'd like to control (as best I can) the types of content that can exist in a document. To that end, I disable controls, and I also intercept pastes to remove some of those content types, e.g. charts. I am aware that this content can also be drag-and-dropped, so I also check for it later, but I'd prefer to stop or warn the user as soon as possible.
I have tried a few strategies:
RTF manipulation
Open XML manipulation
RTF manipulation is so far working fairly well, but I'd really prefer to use Open XML as I expect it to be more useful in the future. I just can't get it working.
Open XML Manipulation
The wonderfully-undocumented (as far as I can tell) "Embed Source" appears to contain a compound document object, which I can use to modify the copied content using the Open XML SDK. But I have been unable to put the modified content back into an object that lets it be pasted correctly.
The modification part seems to work fine. I can see, if I save the modified content to a temporary .docx file, that the changes are being made correctly. It's the return to the clipboard that seems to be giving me trouble.
I have tried assigning just the Embed Source object back to the clipboard (so that the other types such as RTF get wiped out), and in this case nothing at all gets pasted. I've also tried re-assigning the Embed Source object back to the clipboard's data object, so that the remaining data types are still there (but with mismatched content, probably), which results in an empty embedded document getting pasted.
Here's a sample of what I'm doing with Open XML:
using OpenMcdf;
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
...
object dataObj = Forms.Clipboard.GetDataObject();
object embedSrcObj = dateObj.GetData("Embed Source");
if (embedSrcObj is Stream)
{
// read it with OpenMCDF
Stream stream = embedSrcObj as Stream;
CompoundFile cf = new CompoundFile(stream);
CFStream cfs = cf.RootStorage.GetStream("package");
byte[] bytes = cfs.GetData();
string savedDoc = Path.GetTempFileName() + ".docx";
File.WriteAllBytes(savedDoc, bytes);
// And then use the OpenXML SDK to read/edit the document:
using (WordprocessingDocument openDoc = WordprocessingDocument.Open(savedDoc, true))
{
OpenXmlElement body = openDoc.MainDocumentPart.RootElement.ChildElements[0];
foreach (OpenXmlElement ele in body.ChildElements)
{
if (ele is Paragraph)
{
Paragraph para = (Paragraph)ele;
if (para.ParagraphProperties != null && para.ParagraphProperties.ParagraphStyleId != null)
{
string styleName = para.ParagraphProperties.ParagraphStyleId.Val;
Run run = para.LastChild as Run; // I know I'm assuming things here but it's sufficient for a test case
run.RunProperties = new RunProperties();
run.RunProperties.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Text("test"));
}
}
// etc.
}
openDoc.MainDocumentPart.Document.Save(); // I think this is redundant in later versions than what I'm using
}
// repackage the document
bytes = File.ReadAllBytes(savedDoc);
cf.RootStorage.Delete("Package");
cfs = cf.RootStorage.AddStream("Package");
cfs.Append(bytes);
MemoryStream ms = new MemoryStream();
cf.Save(ms);
ms.Position = 0;
dataObj.SetData("Embed Source", ms);
// or,
// Clipboard.SetData("Embed Source", ms);
}
Question
What am I doing wrong? Is this just a bad/unworkable approach?
