XLSX
AlaSQL can export data to Excel 2007 and LibreOffice format with colors and other Excel formatting functions. This also works in IE9.
Please note that when interacting with files AlaSQL will run async. We strongly recommend you to use the promise notation instead of the simple notation: alasql(sql, params, function(data) { console.log(data) })
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/gd7jex9s/
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
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
