I know it is possible to give a cell a name, as answered in the following question:
EPPLUS - Rename Cell
How can you see if a given cell/range has a name and retrieve that name?
There is a property i.e. IsName that can determine the range has a name or not. But it seems not to work properly. I suppose you to query the named cells collection i.e. sheet.Names or book.Names (they contains all the names in the sheet or the book). Then compare FullAddressAbsolute to the given cell to get the named cell you want.
var cell = sheet.Cells["C1"]; // cell you wanna find the name
ExcelNamedRange namedCell = null;
foreach (var item in book.Names)
{
if (item.FullAddressAbsolute.Equals(cell.FullAddressAbsolute))
{
namedCell = item;
break; // if you don't wanna find all
}
}
// if (namedCell == null) --> NOT FOUND
// else
// namedCell.Name : contains the name you wanna retrieve
LINQ can also be used instead of the loop:
namedCell = book.Names.Where(item => item.FullAddressAbsolute.Equals(cell.FullAddressAbsolute)).FirstOrDefault();

I'm trying to get my sheet to automatically recalculate a set of dates within a schedule, in both directions, when a cell is changed.
The code works fine, but I need to add a bunch more columns and I'd really rather not copy/paste/find/replace a load more times. I'm fairly certain I can do this with variables (just looking up the column identifier and feeding that into the code somehow), but I don't know-how.
functJon onEdJt(e) {
var sh = e.source.getActJveSheet();
Jf(sh.getName() === 'Date Calculator' && e.range.getA1NotatJon() === 'C9'
)
{
sh.getRange("C10").setFormula("=WORKDAY(C9,+$C$3)");
sh.getRange("C11").setFormula("=WORKDAY(C10,+10)");
sh.getRange("C12").setFormula("=WORKDAY(C11,+$C$4)");
sh.getRange("C13").setFormula("=WORKDAY(C12,+$C$3)");
sh.getRange("C14").setFormula("=WORKDAY(C13,+10)");
sh.getRange("C15").setFormula("=WORKDAY(C14,+1)");
sh.getRange("C16").setFormula("=WORKDAY(C15,+$C$5)");
}
else Jf (sh.getName() === 'Date Calculator' && e.range.getA1NotatJon()
=== 'C10' )
{
sh.getRange("C9").setFormula("=WORKDAY(C10,-$C$3)");
sh.getRange("C11").setFormula("=WORKDAY(C10,+10)");
sh.getRange("C12").setFormula("=WORKDAY(C11,+$C$4)");
sh.getRange("C13").setFormula("=WORKDAY(C12,+$C$3)");
sh.getRange("C14").setFormula("=WORKDAY(C13,+10)");
sh.getRange("C15").setFormula("=WORKDAY(C14,+1)");
sh.getRange("C16").setFormula("=WORKDAY(C15,+$C$5)");
Ideally the code should then just "work" for any number of columns in the sheet, so I don't need to add more code if I add more columns.
Update
Here's an example of what I'm trying (but it's not working) - attempting to check that the active cell is in row 9 of a specific column before then running the "set.Formula" functions:
function onEdit(e) {
var sh = e.source.getActiveSheet();
var col = e.source.getActiveSheet().getRange().getColumn();
var row = e.source.getActiveSheet().getRange().getRow();
if(sh.getName() === 'Date Calculator' && e.getRange('9',col) )
Event Objects
Even though the code was written as onEdit(e), you didn't take advantage of the Event Objects.
In this answer, the code returns the new value of the edited cell and also the range. The range is then used to work out the row, column and sheet name and these is used for validation as well as for building the ranges and the setFormula
Variables
The code includes variables for the valid range of columns that can be used for data entry (Column C to Column H), and respective input rows (rows 9 and 10). These are expressed as values, but they could just as easily be written into the spreadsheet as assumptions and the values obtained in the code by using getValue.
The absolute cell references used in the setFormula are partly variable (column reference) and part hard-coded (the respective rows-3,4 and 5). If desired, the rows could be variable as well.
Efficiency
There is just one if statement containing one version of the code to build setFormula.
This is achieved by designing the if statement:
1. if the sheet = "Date Calculator" AND
2. if the editColumn is between the valid ColumnStart and ColumnEnd values (Column C to H) AND
3. if the editRow is between the valid Row values (rows 9 or 10) AND
4. if the edited value isn't a blank (length != 0).
The last condition ("edited value is blank") ensures that if cell contents are been deleted (and/or have no value), then the code won't proceed.
Convert column number to letter
I used a routine written by #AdamL found at Convert column index into corresponding column letter; this converts a column number into a letter. It's used to build the "targetcolumn" address in Workdays. It's valid for the letters A-Z; there's a version for letters beyond Z.
Cleanup
If data is entered into row 10 of a given column, then any value in row 9 (of the same column) needs to be deleted. The code does this and also deletes any pre-existing formula dates in the rows below so there is no confusion about the dates derived by the data entry.
function onEdit(e){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetname = "Date Calculator";
var sheet = ss.getSheetByName(sheetname);
// get the event source data
var editedCell = e.range;
var editRow = editedCell.getRow();
var editCol = editedCell.getColumn();
var eValue = e.value;
var editedSheet = editedCell.getSheet().getName();
//Logger.log("DEBUG: the cell = "+editedCell.getA1Notation()+", the column = "+editCol+", the row is "+editRow+", the value is "+eValue+", the edited sheet is "+editedSheet);
// create some variables for column and row range
var columnStart = 3; // Column C
var columnEnd = 8; // Column H
var rowOption1 = 9; // row 9
var rowOption2 = 10 // row 10
// create some variables for target cells
var absolutecolumn = "C";
//var absoluterow1 = 3; // not used
//var absoluterow2 = 4; // not used
//var absoluterow3 = 5; // not used
// test for valid edit in row option 1 // Row 9
if(editedSheet === sheetname && columnEnd >=editCol && editCol>=columnStart && rowOption2>=editRow && editRow>=rowOption1 && eValue.length !=0 ){
//Logger.log("DEBUG: You got the right sheet, the edit is in the right range of columns and the edited row was = "+rowOption1);
if (editRow == rowOption2){
// clear row 9
sheet.getRange((+editRow-1),editCol).clear();
}
// clear following 8 rows of data
sheet.getRange((+editRow+1),editCol,8).clear();
// set the targetcolumn as a letter
var targetcolumn = columnToLetter(editCol);
// set formula for row+1
sheet.getRange((+editRow+1),editCol).setFormula("=WORKDAY("+targetcolumn+editRow+",$"+absolutecolumn+"$3)"); //
// set formula row +2
sheet.getRange((+editRow+2),editCol).setFormula("=WORKDAY("+targetcolumn+(+editRow+1)+",+10)");
// set formula row +3
sheet.getRange((+editRow+3),editCol).setFormula("=WORKDAY("+targetcolumn+(+editRow+2)+",$"+absolutecolumn+"$4)");
// set formula row +4
sheet.getRange((+editRow+4),editCol).setFormula("=WORKDAY("+targetcolumn+(+editRow+3)+",$"+absolutecolumn+"$3)");
// set formula row + 5
sheet.getRange((+editRow+5),editCol).setFormula("=WORKDAY("+targetcolumn+(+editRow+4)+",+10)");
// set formula row + 6
sheet.getRange((+editRow+6),editCol).setFormula("=WORKDAY("+targetcolumn+(+editRow+5)+",+1)");
// set formula row + 7
sheet.getRange((+editRow+7),editCol).setFormula("=WORKDAY("+targetcolumn+(+editRow+6)+",$"+absolutecolumn+"$5)");
// change the background to show entry in rowoption1
sheet.getRange(editRow,editCol).setBackground("yellow");
sheet.getRange((+editRow+1),editCol).setBackground("white");
}
}
function columnToLetter(column)
{
var temp, letter = '';
while (column > 0)
{
temp = (column - 1) % 26;
letter = String.fromCharCode(temp + 65) + letter;
column = (column - temp - 1) / 26;
}
return letter;
}
Screenshot
I have to write a value to a particular cell (say the D4 cell) in my xlsm file. I can see the option of
XLSX.writeFile(workbook, 'out.xlsx');
in the XLSX package documentation (writing functions)
But I am not seeing anything to write a value to a particular cell (where should the values which needs to be written passed?). Or, it is not as clear as the example provided to read a particular cell value.
Would be glad if someone could provide me a simple example of snippet.
This is how I read a particular cell value:
if(typeof require !== 'undefined') XLSX = require('C:\\Program Files\\nodejs\\node_modules\\npm\\node_modules\\xlsx');
var workbook = XLSX.readFile('xlsm');
var first_sheet_name = workbook.SheetNames[0];
var address_of_cell = 'D5';
var worksheet = workbook.Sheets[first_sheet_name];
var desired_cell = worksheet[address_of_cell];
desired_value = (desired_cell ? desired_cell.v : undefined);
console.log('Cell Value is: '+ desired_value);
So to write to a specific cell in a defined sheet - lets say first sheet, you can do:
const XLSX = require('xlsx');
// read from a XLS file
let workbook = XLSX.readFile('test.xls');
// get first sheet
let first_sheet_name = workbook.SheetNames[0];
let worksheet = workbook.Sheets[first_sheet_name];
// read value in D4
let cell = worksheet['D4'].v;
console.log(cell)
// modify value in D4
worksheet['D4'].v = 'NEW VALUE from NODE';
// modify value if D4 is undefined / does not exists
XLSX.utils.sheet_add_aoa(worksheet, [['NEW VALUE from NODE']], {origin: 'D4'});
// write to new file
// formatting from OLD file will be lost!
XLSX.writeFile(workbook, 'test2.xls');
Hope that helps
Modify value in D4
worksheet['D4'].v = 'NEW VALUE from NODE';
This will work only if the cell already defined in the file, but sometimes you will want to write to a new undefined cell.
so, the solution I found for that is:
modify value in new cell- D4
XLSX.utils.sheet_add_aoa(worksheet, [['NEW VALUE from NODE']], {origin: 'D4'});
Using the following code I cannot increment a value in google sheets to be plus one.
function incrementCellValuesByOne() {
// Increments the values in all the cells in the active range (i.e., selected cells).
// Numbers increase by one, text strings get a "1" appended.
// Cells that contain a formula are ignored.
var ss = SpreadsheetApp.getActiveSpreadsheet();
var activeRange = ss.getActiveRange();
var cell, cellValue, cellFormula;
// iterate through all cells in the active range
for (var cellRow = 1; cellRow <= activeRange.getHeight(); cellRow++) {
for (var cellColumn = 1; cellColumn <= activeRange.getWidth(); cellColumn++) {
cell = activeRange.getCell(cellRow, cellColumn);
cellFormula = cell.getFormula();
// if not a formula, increment numbers by one, or add "1" to text strings
// if the leftmost character is "=", it contains a formula and is ignored
// otherwise, the cell contains a constant and is safe to increment
// does not work correctly with cells that start with '=
if (cellFormula[0] != "=") {
cellValue = cell.getValue();
cellValue =+cellValue
cell.setValue(cellValue + 1);
}
}
}
}
For example "personalDataDOB_3" needs to become "personalDaTaDOB_4" I'm looking for a fast way to do this as right now I need to replace the value by typing.
You want to modify "personalDataDOB_3" of a certain cell to "personalDaTaDOB_4". If my understanding is correct, how about this modification?
Modification points :
When the retrieved "personalDataDOB_3" is converted to the number using cellValue =+cellValue, NaN is returned. So even if 1 was added, the result is NaN.
If the format of strings you want to modify is always "personalDataDOB_#", how about separating the string by _?
In order to reflect above points, please modify your script as follows.
From :
if (cellFormula[0] != "=") {
cellValue = cell.getValue();
cellValue =+cellValue
cell.setValue(cellValue + 1);
}
To :
if (cellFormula[0] != "=") {
cellValue = cell.getValue();
var temp = cellValue.split("_"); // Added
temp[1] = Number(temp[1]) + 1; // Added
cell.setValue(temp.join("_")); // Modified
}
Note :
If the format of strings you want to modify is always changed, please tell me.
If I misunderstand your question, I'm sorry.
I'm running into strange problem with .Net version of POI library for Excel Spreadsheets. I'm rewriting from text files to Excel 97-2003 documents and I'm like to add some formatting programmatically depend on some values gather at the begging of the program.
At the beginning, in the same method where I was creating a new cell from given value I was creating also a new Workbook CellStyle which was wrong, because I was running out of the styles very quickly (or I was just thought it was the cause of the problem).
Constructor of the class responsible for Excel Workbook:
public OldExcelWriter(TextWriter logger) : base(logger)
{
_workbook = new HSSFWorkbook();
_sheetData = _workbook.CreateSheet("sheet1");
_creationHelper = _workbook.GetCreationHelper();
}
Method that is calling all the chains of operations:
public void Write(string path, Data data)
{
FillSpreadSheetWithData(data, _sheetData);
SaveSpreadSheet(_workbook, path);
}
Long story short, in FillSpreadSheetWithData I have method for creating a row inside which I'm have a loop for each cell, so basically I'm iterating thru every column, passing IRow references to a row, column value, index and formatting information like this:
for (int j = 0; j < column.Count; j++)
{
CreateCell(row, column[j], j, data.Formatting[j]);
}
and while creating a new styles (for first shot I was trying to pass some date time values) I had situation like this in my rewrited Excel: screenshot of excel workbook
So formatting was passed correctly (also Horizontal Aligment etc.) but it get ugly after 15th row (always the same amount).
DateTime dataCell = DateTime.MaxValue;
var cell = row.CreateCell(columnIndex);
_cellStyle = _workbook.CreateCellStyle();
switch (format.Type)
{
case DataType.Date:
_cellStyle.DataFormat = _creationHelper.CreateDataFormat().GetFormat("m/dd/yyyy");
if (value.Replace("\n", "") != string.Empty)
{
dataCell = DateTime.ParseExact(value.Replace("\n", ""), "m/dd/yyyy",
System.Globalization.CultureInfo.InvariantCulture);
}
break;
}
switch (format.HorizontalAlignment)
{
case Enums.HorizontalAlignment.Left:
_cellStyle.Alignment = HorizontalAlignment.LEFT;
break;
case Enums.HorizontalAlignment.Center:
_cellStyle.Alignment = HorizontalAlignment.CENTER;
break;
}
if (dataCell != DateTime.MaxValue)
{
cell.CellStyle = _cellStyle;
cell.SetCellValue(dataCell);
dataCell = DateTime.MaxValue;
}
else
{
cell.CellStyle = _cellStyle;
cell.SetCellValue(value);
}
(It's not the cleanest code but I will don refactor after getting this work).
After running into this issue I thought that maybe I will create _cellStyle variable in the constructor and only change it's value depends on the case, because it's assigned to the new cell anyway and I see while debugging that object values are correct.
But after creating everything, it won't get any better. Styles was override by the last value of the style, and dates are spoiled also, but later: screnshoot of excel workbook after creating one instance of cell style
I'm running out of ideas, maybe I should create every combination of the cell styles (I'm using only few data formats and alignments) but before I will do that (because I'm running out of easy options right now) I wonder what you guys think that should be done here.
cell format is set to custom with date type
I am using this code to create my custom style and format. Its for XSSF Format of excel sheet. but it will work for HSSF format with some modification.
XSSFFont defaultFont = (XSSFFont)workbook.CreateFont();
defaultFont.FontHeightInPoints = (short)10;
defaultFont.FontName = "Arial";
defaultFont.Color = IndexedColors.Black.Index;
defaultFont.IsBold = false;
defaultFont.IsItalic = false;
XSSFCellStyle dateCellStyle = (XSSFCellStyle)workbook.CreateCellStyle();
XSSFDataFormat dateDataFormat = (XSSFDataFormat)workbook.CreateDataFormat();
dateCellStyle.SetDataFormat(dateDataFormat.GetFormat("m/d/yy h:mm")); //Replace format by m/dd/yyyy. try similar approach for phone number etc.
dateCellStyle.FillBackgroundColor = IndexedColors.LightYellow.Index;
//dateCellStyle.FillPattern = FillPattern.NoFill;
dateCellStyle.FillForegroundColor = IndexedColors.LightTurquoise.Index;
dateCellStyle.FillPattern = FillPattern.SolidForeground;
dateCellStyle.Alignment = HorizontalAlignment.Left;
dateCellStyle.VerticalAlignment = VerticalAlignment.Top;
dateCellStyle.BorderBottom = BorderStyle.Thin;
dateCellStyle.BorderTop = BorderStyle.Thin;
dateCellStyle.BorderLeft = BorderStyle.Thin;
dateCellStyle.BorderRight = BorderStyle.Thin;
dateCellStyle.SetFont(defaultFont);
//Apply your style to column
_sheetData.SetDefaultColumnStyle(columnIndex, dateCellStyle);
// Or you can also apply style cell wise like
var row = _sheetData.CreateRow(0);
for (int cellIndex = 0;cellIndex < TotalHeaderCount;cellIndex++)
{
row.Cells[cellIndex].CellStyle = dateCellStyle;
}
I have some cells (that are non-adjacenet). Each of these has a range name in the form "rLampnn" as below.
ss.getRangeByName("rLamp20").setValue(e.range.getValue());
ss.getRangeByName("rLamp19").setValue(e.range.getValue());
ss.getRangeByName("rLamp18").setValue(e.range.getValue());
I want to put the same value into several of them at once. (Each of them then has a conditional format which changes the cell colour depending on what was entered into them).
Is there a more efficient way (i.e. quicker) of setting the same value into a group of these cells rather than individual calls like above?
If you have many of them you could loop .setValue() using the nn index in the named ranges:
var fName = 'rLamp';
var howManyNamedRanges = 20;
// Assuming the first NamedRange is rLamp0
for (var i=0;i<howManyNamedRanges;i++) {
ss.getRangeByName(fName+i).setValue(e.range.getValue());
}
If the first named ranges is 1 or else you could change it to:
var fName = 'rLamp';
var firstNamedRange = 4;
var lastNamedRange = 20;
// Assuming the first NamedRange is rLamp[n]
for (var i=firstNamedRange;i<=lastNamedRange;i++) {
ss.getRangeByName(fName+i).setValue(e.range.getValue());
}
