Working with GridJs Server Side

1. set the right folder path in Config

use Config.set_file_cache_directory to set the cache path.

 Config.set_file_cache_directory('c:/storage/cache/')

for the storage detail ,please check this guide

2. Get json from the spreadsheet file.

path='c:/files/example.xlsx'
gwb = new GridJsWorkbook();
gwb.ImportExcelFile(path);
 
ret =gwb.export_to_json();

3. Get the images/shapes from the spreadsheet file

# Gridjs will automatically zip all the images/shapes into a zip stream  and store it in cache  
 

# get the fileid in the cache,uid is the unique id for the spreadsheet  instance, sheetid is the sheet index,
fileid=(uniqueid + '.' + (sheetid + '_batch.zip'))

# get the zip file  by the fileid
os.path.join(Config.file_cache_directory, fileid)

4. Update spreadsheet file in cache

gwb = new GridJsWorkbook();
# p is the update json,uid is the unique id for the spreadsheet
ret = gwb.UpdateCell(p, uid);

5. Save spreadsheet file in cache

gwb = new GridJsWorkbook();
# p is the update json,uid is the unique id for the spreadsheet
gwb.merge_excel_file_from_json(uid, p);
gwb.save_to_cache_with_file_name(uid, filename,password);
