XLSX
To work with .xlsx
files, please include xlsx
from https://cdnjs.com/libraries/xlsx
<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/X.Y.Z/xlsx.core.min.js"></script>
Please note that when interacting with files AlaSQL will run async. We strongly recommend you to use the promise notation.
alasql.promise('select City, Population from xlsx("cities.xlsx") where Population > 100000')
.then(function(data){
console.log(data);
}).catch(function(err){
console.log('Error:', err);
});
alasql.promise('SELECT * INTO XLSX("restest280b.xlsx") FROM ?', [data])
.then(function(data){
console.log('Data saved');
}).catch(function(err){
console.log('Error:', err);
});
To store data in multiple sheets have a look at http://jsfiddle.net/np3pea44/
XLSX() function supports the following options:
Sheet name:
alasql.promise('select * from xlsx("cities.xlsx",{sheetid:"Sheet2"})')
.then(function(data){
console.log(data);
}).catch(function(err){
console.log('Error:', err);
});
By default AlaSQL read data from sheet "Sheet1".
Cells range:
alasql.promise('select * from xlsx("cities.xlsx",{range:"A1:D100"})')
.then(function(data){
console.log(data);
}).catch(function(err){
console.log('Error:', err);
});
By default AlaSQL read all data in the sheet.
Read headers from data range (true/false):
alasql.promise('select * from xlsx("cities.xlsx",{headers:true})')
.then(function(data){
console.log(data);
}).catch(function(err){
console.log('Error:', err);
});
By default AlaSQL headers are set to true
var mystyle = {
headers:true,
column: {style:{Font:{Bold:"1"}}},
rows: {1:{style:{Font:{Color:"#FF0077"}}}},
cells: {1:{1:{
style: {Font:{Color:"#00FFFF"}}
}}}
};
alasql.promise('SELECT * INTO XLSXML("restest280b.xls",?) FROM ?',[mystyle,data])
.then(function(data){
console.log('Data saved');
}).catch(function(err){
console.log('Error:', err);
});
See the working example in jsFiddle
Please note that you can avoid letting AlaSQL try to add extension to filenames by setting autoExt:false
in the option.
You can also pass the file as a Blob:
alasql('SELECT * FROM XLSX(?)',[myblobData]);
AlaSQL uses js-xlsx library to read and export Excel files.
js-xlsx at Github: https://github.com/SheetJS/js-xlsx
By default AlaSQL look through first 10 records to collect infomation about all columns. You can change this flag to be sure that AlaSQL collect information about all columns in all records (it may take a time for large recordsets).
alasql.options.columnlookup = 10;
To read blank column values from xls,xlsx and csv you can use this notation for column names [0],[1],[2] like:
SELECT [0],[2] FROM XLS('filename.xls') WHERE [3] > 100
Problem with dates when you read your file? Have a look at this comment
Or use the XLSXopts celldates to convert Excel dates to JS date objects: ´SELECT * FROM xlsx("test/test815.xlsx", {XLSXopts: {cellDates: true}})
Uploading files directly into AlaSQL? Have a look at https://github.com/agershun/alasql/issues/971#issuecomment-360121191
