Hunter 21.3 253 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).

Hunter 32.1 300 The following steps take HMI simulator as example:
301
302 ~1. Click button "Create Table" to draw lua table in screen.
303
304 (% style="text-align:center" %)
305 [[image:csvGenerateSteps.png]]
306
307 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.
308
309 (% style="text-align:center" %)
310 [[image:csvGenerateSimulationPath.png]]
311
312 3. Click button "upload" to upload csv file into server side. In this case, we can check the upload path for PC.
313
314 (% style="text-align:center" %)
315 [[image:csvGenerateServerPath.png]]
316
Hunter 35.1 317 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":

Hunter 41.1 571
Hunter 43.1 572 1) The file path is set as Sheet_2023_06_13_15_29_45.csv at the root path for USB;
Hunter 42.1 573
574 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;

579 3) The reading content is a two-dimensional table, can use the table index to locate the specify data cell;
580
581 For example, want to read the 2nd row C column from the table, the table index will be like table[2][3].
