Flutter - Convert data from firestore into Excel sheet - excel

How to convert data from Firestore Into an Excel sheet on both Android app and flutter web?
Any response will be appreciated... thanks in advance!

Excel library for flutter
You can go through the documentation here.
Now as jay asked to explain in detail how you are gonna retrive the data and store it in the excel sheet,
First step,
var excel = Excel.createExcel(); //create an excel sheet
Sheet sheetObject = excel['SheetName']; //create an sheet object
Second step, commands to write in excel sheet,
where A is column id and 1 is row.
var cell = sheetObject.cell(CellIndex.indexByString("A1"));
cell.value = 8; // Insert value to selected cell;
Third step, getting data from firebase
QuerySnapshot _qs =
await _notificationRef.where('language', isEqualTo: selectedLang).get(); // Lets say I have some collection where I need to get some documents with specific language
//This loop will iterate in all of the documents in the collection
for (int i = 0; i < _qs.docs.length; i++) {
string data = _qs.docs[i].data()['names']; //Where name is the field value in the document and i is the index of the document.
}
});
Now if we combine second and third step
QuerySnapshot _qs =
await _notificationRef.where('language', isEqualTo: selectedLang).get();
for (int i = 0; i < _qs.docs.length; i++) {
var cell = sheetObject.cell(CellIndex.indexByString('A${i+1}')); //i+1 means when the loop iterates every time it will write values in new row, e.g A1, A2, ...
cell.value = _qs.docs[i].data()['names']; // Insert value to selected cell;
}
});
Once you are done with the data part you can save the file,
// Save the Changes in file
excel.encode().then((onValue) {
File(join("Path_to_destination/excel.xlsx"))
..createSync(recursive: true)
..writeAsBytesSync(onValue);
});
Once you are done with the saving you can choose any of the library to share your sheet to others,
Usually this libraries asks you to provide a file or file path
which you can easily provide using the last code block explained where I passed file path to join method

match single cell value with column of values for every match return those rows Google-apps-script

I have a spreadsheet with 2 tabbed sheets. I am trying to run a macro so that when the user inputs a name in B2 of the 2nd sheet, it is matched with every instance of that name in the 1st sheet, column B. I then need to copy all of the data that appears in the matched cell's rows and have that pasted in the 2nd sheet starting with cell B3.
I have limited experience with VBA, but none with JS/Google-apps-script. Any help with how to write this would be greatly appreciated! Here is my first shot:
function onSearch() {
// raw data sheet
var original = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 2");
// search for student sheet
var filtered = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Student Progress Search");
// retrieving the values in the raw data array of names
var searchColumn = 2;
var lr = original.getLastRow();
var searchRange = original.getRange(2,searchColumn, lr, 1).getValues();
// retrieving the name submitted on search
var inputName = filtered.getRange(2, 2).getValue();
// loop through all the names in the raw data and identify any matches to the search name
for (var i = 0; i < lr; i++){
var dataValue = searchRange[i];
var r = dataValue.getRow();
var line = [[r]];
var paste = filtered.getRange(3, 3);
// if the data is a match, return the value of that cell in the searched sheet
if (dataValue == inputName){ return paste.setValues(line);
}
}
}
Not sure if the built-in QUERY function would work for you. This here does exactly what you are looking for:
=QUERY(Sheet1!B:B,"select B where LOWER(B) like LOWER('%" &B2& "%')")
For example, if a user enters 'joe', the function will match any entry containing 'joe', regardless of case.

Delete rows after a date has passed automatically for Google Spreadsheets [duplicate]

I'd like to be able to delete an entire row in a Google Spreadsheets if the value entered for say column "C" in that row is 0 or blank. Is there a simple script I could write to accomplish this?
Thanks!
I can suggest a simple solution without using a script !!
Lets say you want to delete rows with empty text in column C.
Sort the data (Data Menu -> Sort sheet by column C, A->Z) in the sheet w.r.t column C, so all your empty text rows will be available together.
Just select those rows all together and right-click -> delete rows.
Then you can re-sort your data according to the column you need.
Done.
function onEdit(e) {
//Logger.log(JSON.stringify(e));
//{"source":{},"range":{"rowStart":1,"rowEnd":1,"columnEnd":1,"columnStart":1},"value":"1","user":{"email":"","nickname":""},"authMode":{}}
try {
var ss = e.source; // Just pull the spreadsheet object from the one already being passed to onEdit
var s = ss.getActiveSheet();
// Conditions are by sheet and a single cell in a certain column
if (s.getName() == 'Sheet1' && // change to your own
e.range.columnStart == 3 && e.range.columnEnd == 3 && // only look at edits happening in col C which is 3
e.range.rowStart == e.range.rowEnd ) { // only look at single row edits which will equal a single cell
checkCellValue(e);
}
} catch (error) { Logger.log(error); }
};
function checkCellValue(e) {
if ( !e.value || e.value == 0) { // Delete if value is zero or empty
e.source.getActiveSheet().deleteRow(e.range.rowStart);
}
}
This only looks at the value from a single cell edit now and not the values in the whole sheet.
I wrote this script to do the same thing for one of my Google spreadsheets. I wanted to be able to run the script after all the data was in the spreadsheet so I have the script adding a menu option to run the script.
/**
* Deletes rows in the active spreadsheet that contain 0 or
* a blank valuein column "C".
* For more information on using the Spreadsheet API, see
* https://developers.google.com/apps-script/service_spreadsheet
*/
function readRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
var values = rows.getValues();
var rowsDeleted = 0;
for (var i = 0; i <= numRows - 1; i++) {
var row = values[i];
if (row[2] == 0 || row[2] == '') {
sheet.deleteRow((parseInt(i)+1) - rowsDeleted);
rowsDeleted++;
}
}
};
/**
* Adds a custom menu to the active spreadsheet, containing a single menu item
* for invoking the readRows() function specified above.
* The onOpen() function, when defined, is automatically invoked whenever the
* spreadsheet is opened.
* For more information on using the Spreadsheet API, see
* https://developers.google.com/apps-script/service_spreadsheet
*/
function onOpen() {
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var entries = [{
name : "Remove rows where column C is 0 or blank",
functionName : "readRows"
}];
sheet.addMenu("Script Center Menu", entries);
};
Test spreadsheet before:
Running script from menu:
After running script:
I was having a few problems with scripts so my workaround was to use the "Filter" tool.
Select all spreadsheet data
Click filter tool icon (looks like wine glass)
Click the newly available filter icon in the first cell of the column you wish to search.
Select "Filter By Condition" > Set the conditions (I was using "Text Contains" > "word")
This will leave the rows that contain the word your searching for and they can be deleted by bulk selecting them while holding the shift key > right click > delete rows.
This is what I managed to make work. You can see that I looped backwards through the sheet so that as a row was deleted the next row wouldn't be skipped. I hope this helps somebody.
function UpdateLog() {
var returnSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('RetLog');
var rowCount = returnSheet.getLastRow();
for (i = rowCount; i > 0; i--) {
var rrCell = 'G' + i;
var cell = returnSheet.getRange(rrCell).getValue();
if (cell > 0 ){
logSheet.
returnSheet.deleteRow(i);
}
}
}
quite simple request. Try this :
function try_It(){
deleteRow(2); //// choose col = 2 for column C
}
function deleteRow(col){ // col is the index of the column to check for 0 or empty
var sh = SpreadsheetApp.getActiveSheet();
var data = sh.getDataRange().getValues();
var targetData = new Array();
for(n=0;n<data.length;++n){
if(data[n][col]!='' && data[n][col]!=0){ targetData.push(data[n])};
}
Logger.log(targetData);
sh.getDataRange().clear();
sh.getRange(1,1,targetData.length,targetData[0].length).setValues(targetData);
}
EDIT : re-reading the question I'm not sure if the question is asking for a 'live' on Edit function or a function (like this above) to apply after data has been entered... It's not very clear to me... so feel free to be more accurate if necessary ;)
There is a simpler way:
Use filtering to only show the rows which you want to delete. For example, my column based on which I want to delete rows had categories on them, A, B, C. Through the filtering interface I selected only A and B, which I wanted to delete.
Select all rows and delete them. Doing this, in my example, effectively selected all A and B rows and deleted them; now my spreadsheet does not show any rows.
Turn off the filter. This unhides my C rows. Done!
There is a short way to solve that instead of a script.
Select entire data > Go to menu > click Data tab > select create filter > click on filter next to column header > pop-up will appear then check values you want to delete > click okay and copy the filtered data to a different sheet > FINISH
reading your question carefully, I came up with this solution:
function onOpen() {
// get active spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
// create menu
var menu = [{name: "Evaluate Column C", functionName: "deleteRow"}];
// add to menu
ss.addMenu("Check", menu);
}
function deleteRow() {
// get active spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
// get active/selected row
var activeRow = ss.getActiveRange().getRowIndex();
// get content column C
var columnC = ss.getRange("C"+activeRow).getValue();
// evaluate whether content is blank or 0 (null)
if (columnC == '' || columnC == 0) {
ss.deleteRow(parseInt(activeRow));
}
}
This script will create a menu upon file load and will enable you to delete a row, based on those criteria set in column C, or not.
This simple code did the job for me!
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet(); // get active spreadsheet
var activeRow = ss.getActiveRange().getRowIndex(); // get active/selected row
var start=1;
var end=650;
var match='';
var match2=0; //Edit this according to your choice.
for (var i = start; i <= end; i++) {
var columnC = ss.getRange("C"+i).getValue();
if (columnC ==match || columnC ==match2){ ss.deleteRow(i); }
}
}
The below code was able to delete rows containing a date more than 50 days before today in a particular column G , move these row values to back up sheet and delete the rows from source sheet.
The code is better as it deletes the rows at one go rather than deleting one by one. Runs much faster.
It does not copy back values like some solutions suggested (by pushing into an array and copying back to sheet). If I follow that logic, I am losing formulas contained in these cells.
I run the function everyday in the night (scheduled) when no one is using the sheet.
function delete_old(){
//delete > 50 day old records and copy to backup
//run daily from owner login
var ss = SpreadsheetApp.getActiveSpreadsheet();
var bill = ss.getSheetByName("Allotted");
var backss = SpreadsheetApp.openById("..."); //backup spreadsheet
var bill2 = backss.getSheetByName("Allotted");
var today=new Date();
//process allotted sheet (bills)
bill.getRange(1, 1, bill.getMaxRows(), bill.getMaxColumns()).activate();
ss.getActiveRange().offset(1, 0, ss.getActiveRange().getNumRows() - 1).sort({column: 7, ascending: true});
var data = bill.getDataRange().getValues();
var delData = new Array();
for(n=data.length-1; n>1; n--){
if(data[n][6] !=="" && data[n][6] < today.getTime()-(50*24*3600*1000) ){ //change the condition as per your situation
delData.push(data[n]);
}//if
}//for
//get first and last row no to be deleted
for(n=1;n<data.length; n++){
if(data[n][6] !=="" && data[n][6] < today.getTime()-(50*24*3600*1000) ){
var strow=n+1 ; //first row
break
}//if
}//for
for(n=data.length-1; n>1; n--){
if(data[n][6] !=="" && data[n][6] < today.getTime()-(50*24*3600*1000) ){
var ltrow=n+1 ; //last row
break
}//if
}//for
var bill2lr=bill2.getLastRow();
bill2.getRange((bill2lr+1),1,delData.length,delData[0].length).setValues(delData);
bill.deleteRows(strow, 1+ltrow-strow);
bill.getRange(1, 1, bill.getMaxRows(), bill.getMaxColumns()).activate();
ss.getActiveRange().offset(1, 0, ss.getActiveRange().getNumRows() - 1).sort({column: 6, ascending: true}); //get back ordinal sorting order as per column F
}//function

for loop only reading one row

im trying use for loop on this to loop from datasheet, but its only reading one row, dont know where i did wrong any Ideas?
import org.apache.poi.xssf.usermodel.*;
import org.apache.poi.ss.usermodel.DataFormatter
cellDataFormatter = new DataFormatter()
//Create formula evaluator
fEval = new XSSFFormulaEvaluator(context.srcWkSheet.getWorkbook())
//Increment the rowcounter then read in the next row of items
RC = context.rowCounter;
if(RC<=context.srcWkSheet.getLastRowNum()){//Check if we've reached the last row
for(int i =0; i < RC; i++)
{
curTC = testRunner.testCase
sourceRow = context.srcWkSheet.getRow(i)//Get a spreadsheet row
//Step through cells in the row and populate property data
data1Cell = sourceRow.getCell(0)
curTC.setPropertyValue("data1",cellDataFormatter.formatCellValue(data1Cell ,fEval))
data2Cell = sourceRow.getCell(1)
curTC.setPropertyValue("data2",cellDataFormatter.formatCellValue(data2Cell ,fEval))
data3Cell = sourceRow.getCell(2)
curTC.setPropertyValue("data3",cellDataFormatter.formatCellValue(data3Cell ,fEval))
//Rename test cases for readability in the TestSuite log
curTC.getTestStepAt(0).setName("data1-" + curTC.getPropertyValue("BC"))
//Go back to first test request with newly copied properties
testRunner.gotoStep(0)
}
}
From the API documentation for testRunner.gotoStep(0):
Transfers execution of this TestRunner to the TestStep with the specified index in the TestCase
Execution will continue after the indexed step. You are probably expecting it will return back to your loop, which is incorrect!
You probably meant something like: curTC.getTestStepAt(0).run(context.testRunner, context); API documentation.
You could also have an issue with the excel file you are providing. XSSFFormulaEvaluator I believe is only for old style *.xls excel format. Could be an issue if you're feeding *.xlsx format excel file.
In SoapUI NG Pro there's a DataSource test step that simply allows you to point to a file (xls or xlsx) and feed in the data

Find value in spreadsheet using google script

Situation:
1 spreadsheet
multiple sheets
1 cell selected (may vary)
What I'd like to do is to find and set focus to the next cell in any sheet that matches the selected cell (case insensitive) upon clicking a button-like image in the spreadsheet. Sort of like a custom index MS Word can create for you.
My approach is:
- set value of the selected cell as the variable (succeeded)
- find the first cell that matches that variable (not the selected cell) (no success)
- set value of found cell as variable2 (no success)
- set the focus of spreadsheet to variable2 (no success)
function FindSetFocus()
{
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var activecell = sheet.getActiveCell();
var valueactivecell = activecell.getValue();
//here comes the code :)
}
I have found this snippet in the following topic, but I'm having a little trouble setting the input and doing something with the output: How do I search Google Spreadsheets?
I think I can replace 'value' with 'valueactivecell', but I don't know how to set the range to search through all sheets in the spreadsheet. Also, I'd like the output to be something I can set focus to using something like 'ss.setActiveSheet(sheet).setActiveSelection("D5");'
/**
* Finds a value within a given range.
* #param value The value to find.
* #param range The range to search in.
* #return A range pointing to the first cell containing the value,
* or null if not found.
*/
function find(value, range) {
var data = range.getValues();
for (var i = 0; i < data.length; i++) {
for (var j = 0; j < data[i].length; j++) {
if (data[i][j] == value) {
return range.getCell(i + 1, j + 1);
}
}
}
return null;
}
also found this but no luck on getting it to work on the selected cell and setting focus: How do I search for and find the coordinates of a row in Google Spreadsheets best answer, first code.
Please bear in mind that I'm not a pro coder :) If code samples are provided, please comment inline hehe.
Thanks in advance for any help.
Edit 24/10: Used the code from the answer below and edited it a bit. Now able to look through multiple sheets in a spreadsheet to find the value. The only problem with this bit is: My cell is highlighted yellow, but the cell with the value found isn't selected. See code below for hopping through sheets. I can't get my head around this :)
function SearchAndFind() {
//determine value of selected cell
var sh = SpreadsheetApp.getActiveSpreadsheet();
var ss = sh.getActiveSheet();
var cell = ss.getActiveCell();
var value = cell.getValue();
//create array with sheets in active spreadsheet
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
//loop through sheets to look for value
for (var i in sheets) {
//Set active cell to A1 on each sheet to start looking from there
SpreadsheetApp.setActiveSheet(sheets[i])
var sheet = sh.getActiveSheet();
var range = sheet.getRange("A1");
sheet.setActiveRange(range);
//set variables to loop through data on each sheet
var activeR = cell.getRow()-1;
var activeC = cell.getColumn()-1;
var data = sheets[i].getDataRange().getValues()
var step = 0
//loop through data on the sheet
for(var r=activeR;r<data.length;++r){
for(var c=activeC;c<data[0].length;++c){
step++
Logger.log(step+' -- '+value+' = '+data[r][c]);
if(data[r][c]==''||step==1){ continue };
if(value.toString().toLowerCase()==data[r][c].toString().toLowerCase()){
sheet.getRange(r+1,c+1).activate().setBackground('#ffff55');
return;
}
}
}
}
}
Here is an example of such a function, I inserted a drawing in my spreadsheet representing a button which I assigned the script so it's easy to call.
I added a feature to set a light yellow background on the resulting selected cell so it's easier to see the selected cell but this is optional.
Code
function findAndSelect(){
var sh = SpreadsheetApp.getActiveSpreadsheet();
var ss = sh.getActiveSheet();
var cell = ss.getActiveCell();
cell.setBackground('#ffff55');// replace by cell.setBackground(null); to reset the color when "leaving" the cell
var activeR = cell.getRow()-1;
var activeC = cell.getColumn()-1;
var value = cell.getValue();
var data = ss.getDataRange().getValues();
var step = 0
for(var r=activeR;r<data.length;++r){
for(var c=activeC;c<data[0].length;++c){
step++
Logger.log(step+' -- '+value+' = '+data[r][c]);
if(data[r][c]==''||step==1){ continue };
if(value.toString().toLowerCase()==data[r][c].toString().toLowerCase()){
ss.getRange(r+1,c+1).activate().setBackground('#ffff55');
return;
}
}
}
}
Caveat
This code only searches 'downwards', i.e. any occurrence in a row that would precede the selected cell is ignored, same for columns...
If that's an issue for you then the code should be modified to start iterating from 0. But in this case if one need to ignore the initial starting cell then you should also memorize its coordinates and skip this value in iteration.

Get and use user data from another sheet in Google Docs

We use google spreadsheets for reporting by quite a big number of users.
I have written a basic script, which opens a specific sheet depending on the current user:
var CurrentUser = Session.getUser().getEmail()
var ss = SpreadsheetApp.getActive();
switch(CurrentUser){
case "usermail1#gmail.com":
SpreadsheetApp.setActiveSheet(ss.getSheetByName("sheet1"));
break;
case "usermail2#gmail.com":
SpreadsheetApp.setActiveSheet(ss.getSheetByName("sheet2"));
break;
case "usermail3#gmail.com":
SpreadsheetApp.setActiveSheet(ss.getSheetByName("sheet3"));
break;
etc...
I would like to put the userdata and sheetnames into an external table and get these data depending on that table, so it is easier to maintain the list of e-mails and users.
How can I get data from a specific google spreadsheet and let the script work according to that?
You can try this. It simulates a VLOOKUP on a different sheet and switches to the 'matched' sheet in your current workbook. This doesn't handle non-matches, but that should be relatively straightforward to add to suit your case.
function switchSheets() {
// Current sheet
var ss = SpreadsheetApp.getActive();
// Target sheet (using the key found in the URL)
var target = SpreadsheetApp.openById("my_other_sheet_id");
var rows = target.getDataRange();
var values = rows.getValues();
// Get the current user
var CurrentUser = Session.getUser().getEmail();
// Now iterate through all of the rows in your target sheet,
// looking for a row that matches your current user (this assumes that
// it will find a match - you'll want to handle non-matches as well)
for (var i = 1; i <= rows.getNumRows() - 1; i++) {
// Match the leftmost column
var row = values[i][0];
if (row == CurrentUser) {
// If we match, grab the corresponding sheet (one column to the right)
target_sheet = values[i][1];
break;
}
}
// Now switch to the matched sheet (rememeber to handle non-matches)
ss.setActiveSheet(ss.getSheetByName(target_sheet));
};
