MATLAB 2012 - Create Single list text file from matlab - excel

I have solved an equation on matlab and have 8760 output data that needs to be put into a single list for excel. that is in Excel A1 to A8760, going down not across.
I have tried the save, fprintf however the data out put does not come out right.
I have only one variable I need and that is 's'
The file name of the resulting text file does not matter. I just need it to be saved as a single list of numbers to examine in excel.
Thank you for reading

xlswrite('yourdata.xlsx',s)
Try transposing your vector if your result is horizontal and not vertical. That is:
xlswrite('yourdata.xlsx',s.')
See documentation for more information.

You can use the matlab's function xlswrite (doc) that will write an array (s) to the first worksheet in Excel file.
Alternatively, Matlab could be used to inspect your array.

AnyLogic: False number format when exporting data to excel

I collect various data in time plots. If I copy the timeplot data and then paste it into Excel, the number format is often wrong. For example, I often get a date like Aug 94 instead of the actual number from the TimePlot. Unfortunately, I can't easily format this date into a number either, since the formatted number does not match the actual number from the timeplot. If I format the date in the same format as the number above and below, then I get the number 34547. However, this number does not correspond to the actual number of the TimePlot. Anyone know how I can prevent this problem?
You can only solve this on the Excel side, AnyLogic provides the raw data for you. Excel then interprets stuff. You can test it by pasting the chart raw data into a txt or csv file.
So either fix your Excel settings or paste into a csv, then into an xlsx.
Or better still: Do not manually paste at all. Instead, write your model results into the AnyLogic database and export to Excel from there: this takes away a lot of the pain for you. Check the example models to learn how to do that.
This is not AnyLogic question, rather an Excel & computer formatting problem. One way of resolving this is changing computer's date and time settings.
Another way is to save your output at txt file in AnyLogic. Replace all . with ,. Then open empty Excel, select Text format for the columns. Copy-paste from the txt file.
In Excel there are a few options
when you paste use paste as text only option
But this does not always work as Excel will still try to format the stuff for you
Use the Paste Special option and then choose text
Also possible this will not work, based on your Excel settings.
Paste using the text import wizard
(This works for me without fail)
On step 2 choose tab delimited
On step 3 choose Column format as text for every column (you need to select them in the little diagram below)
You will then see the data exactly as it came from AnyLogic. See the example below where I purposefully imported some text which has something that Excel will think is a date. You will now be able to see what in your data made Excel thing your data needed to be formatted the way it is and then you can fix it. (post a new question if you struggle with this conversion)
But as noted by other answers first prize is to write all the important data to external files. But I know that even I sometimes want to export data from a chart and review it in Excel. Option 3 works for me everytime

Excel Numeric Format Data

I have this data that I exports from some ERP in Citrix to the same Excel in Citrix,
Some example when i paste:
Doc.Curr.
-4,248,057.00
-25,998,733.00
25,998,733.00
-192,534.00
-118,509.00
192,534.00
But when i export this to a Excel in MacOS doesnt recognize like a number format, only like data without format, how can i solve this?
Many systems that export to Excel produce text instead of number. This has to do with the way that the system report was built in the exporting system. For example, the system report uses spaces to separate report columns. Excel parses the data according to the spacing but will not convert the text to numbers. In such a case you need to do that yourself
There are several ways to convert text to numbers, including
copy a cell with a zero, use paste special to paste over the text that should be numbers, using the option to "Add"
use text to columns on one column of numbers
If you need to do that on a regular basis, you may want to look into Power Query (Get and Transform) to load the data and perform any cleanup in there. It will be faster in the long run.

Load data from excel to matlab

I'm trying to download data from excel to matlab. I downloaded data from yahoo finance. I want to load them in matlab however it's not successful. Right down here you have my codes and the message matlab is sending to me. Can somebody help me to improve my codes?
load SP100Duan.csv
Error using load
Number of columns on line 18 of ASCII file C:\Users\11202931\Desktop\SP100Duan.csv
must be the same as previous lines.
There are a TON of ways to get data into MATLAB. Generally speaking, mixed text/numbers gives MATLAB problems. You may want to clean up the excel file so there is no text in columns that should be numbers. Some possible methods to load data:
Use readtable function. Eg. mytable = readtable('mycsvfile.csv') All your data is put a table datatype, which I personally find convenient.
You can read data directly from an excel file using xlsread function. From your description, it sounds like your datatype is a .csv file though.
Use csvread function.
You can often copy and paste data in excel directly into a variable in Matlab. eg. (i) type: x = 0, then (ii) double click on x variable in your workspace, then (iii) copy data from excel and paste into your x variable (iv) execute something like save mydata.mat so you can later load it with load mydata.mat
This should be pretty simple . . .
xlsread('C:\Apple.xls', 'Sheet1', 'A1:G10')

How to save excel columns with long numbers into csv?

Funny thing when I want to save Excel columns with long numbers like below, resulting csv contains converted numbers to scientific notation which is unusable. I want them to be save as text. Any trick to do that?
28160010390002003505456159
12160010390002003505456156
39160010390002003505456155
39160010390002003505456155
Append a TAB char (ASCII 9) at the end of a number.
In order to have those long (>15 digit) numbers in Excel, they are already formatted as text. I suspect that the .csv file also shows them as long numbers (if you open the csv file with Notepad), but that when you open the csv file in Excel, you see them as truncated and converted to scientific notation.
If that is the case, what you need to do is IMPORT the csv file. When you do that, the text-to-columns wizard will open, and allow you to format that column as text. The location of the Import is different in different versions. In Excel 2007, it is on the Data ribbon, Get External Data / From Text.
put the number as a function like below:
="123456789123456789"
If, as the original question seems to imply, you are actually:
already working with data in Excel, and
want to save to a CSV format without losing digits in an extra long number,
Then, before doing a 'Save As' to your CSV format, try formatting the column with a custom format, and in the box for the pattern just type #. This will force Excel to see it as a number, however many digits long, without trying to do something else with it like 4.52364E+14 when you actually save it to CSV.
At least, that is how it works for me in Excel 365 at this point in time.
If you are trying to get data into Excel from a CSV, then the answer about using the data import wizard is probably the safest bet instead.
This is an old question, but since at the moment it's still the top result on a google search for the topic, I think the thread should be kept current. Hussein mahyoub provided the only real answer to the question, yet has not gotten the up-votes.
The answer which tells us to add a tab character after your number gets you an string of text with a tab after it inside excel. It looks visually correct, but, it's not correct inside the spreadsheet. If the intent is to use the data in excel as excel data and use formula etc, it could cause problems. Interestingly if you put the tab before the text, it shows up in the data after the text.
The answer which tells us inserting a ' before the text gets a ' in the excel file. It's visually an incorrect representation of the data.
The answer which boasts the virtue of openoffice is simply an evil troll which does not even attempt to answer the question.
The answer that explains how to import a CSV that has not been properly formatted is good information, but, off topic.
The direct answer to the question is
converted to text,largest number
="123456789012",12345678901
Convert the numeric to text using text function.
Text(number,"0")
using openoffice you can save in csv format without problems.
Don't use Export to csv feature in Excel.
You can easy format that column to number in Excel, then use "Save as" it with csv and "yes" to confirm that you want to keep the format in csv.
That is work for me
Click on the column that has scientific exponent number and go to Format cells and then Numbers (decimal point as 0), save it as MSDOS CSV. Worked for me.

display preceeding zeros in csv file when viewing in excel

Is this at all possible?
If I open up my file in standard text editor e.g. notepad the preceeding zeros are displayed.
e.g. 000485001 shows up.
Although this doesn't happen in excel. All that's displayed is 485001
Just wondering if there's a way around this?
Thanks,
Yes, when you're importing (or using 'Text to columns') you can explicitly indicate the data type for a column (instead of General). If you select 'Text' the zeros will not be dropped.
Unfortunately you only see the dialog to specify this option when Excel is already open and you use either File/Open or Data/Text to Columns. If you just double click a .csv in the explorer you don't get this choice.
Excel tries very hard to determine the type of value it's importing. If it looks like a number, it will treat it like a number, and drop all the leading zeros as it reads it in. There's no way to get them back once they're lost.
You might try to import the file using the wizard that lets you set the data type for each column.
Rather than writing your data as a CSV file, use the SYLK (Symbolic Link) format instead. This format includes information about the style of a column, so that Excel will not try to auto-guess the type of data.
The easiest way to get started with this format is to export a small file from Excel and use that as a template.
Ok got around this by inserting a text character before the number i.e. #000485001
Simple enough!
