264 So we decode this json into lua object, and then assign the values from "Value" field into table (addresses HDW1~~HDW101, HDW112~~HDW202, HDW213~~HDW313, HDW324~~HDW424).

315
316 The following steps take HMI simulator as example:
317
318 ~1. Click button "Create Table" to draw lua table in screen.
319
320 (% style="text-align:center" %)
321 [[image:csvGenerateSteps.png]]
322
323 2. Click button "Save as csv" to save the file into HMI storage path. On the HMI simulator, user can enter the simulation path of U disk to check the file whether create successfully.
324
325 (% style="text-align:center" %)
326 [[image:csvGenerateSimulationPath.png]]
327
328 3. Click button "upload" to upload csv file into server side. In this case, we can check the upload path for PC.
329
330 (% style="text-align:center" %)
331 [[image:csvGenerateServerPath.png]]
332
333 The csv file generation is mainly using the following function to implement, the customized data is argument tab, and csv file storage path in HMI is "udisk:weather1.csv":
334
335 (% style="text-align:center" %)
336 [[image:csvGenerateLuaCode.png]]

586 The core code is from file readcsv.lua:
587
588 1) The file path is set as Sheet_2023_06_13_15_29_45.csv at the root path for USB;
589
590 2) Remember to change csv separator in the second parameter from function csv_csvToTable according to user's need, this demo is using **semicolon** as separator;
591

593 [[image:CSVreadwithsemicolon.png]]
594
595 3) The reading content is a two-dimensional table, can use the table index to locate the specify data cell;
596
597 For example, want to read the 2nd row C column from the table, the table index will be like table[2][3].
