Hi everyone, I'm trying to use the "simulate arbitriry signal" function to simulate a ground motion. When I define signal here, it can only read lvm format file. I wondered if there's anyway I can convert an excel file or txt file into lvm format so that I can use this function?
I'm trying to use the attached vi to input a groundmotion so that I can simulate an earthquake using a shake table. However the function I'm using, "simulate arbitrary signal express vi", only read lvm file.
I was trying to generate the signal from the data but failed. So I went back to trying to use the simulate arbitrary signal function. I wrote a vi that's suppose to convert the excel file to a lvm file. And attached is the generated lvm file that seems wrong. Can you help me to look at the read_signal vi? Thanks a lot.
Excel is a Microsoft Office product that writes "Excel Files", files in a somewhat proprietary format that have the extension .xls or .xlsx. You are dealing with a "comma-separated variable", or .csv, file that (again, by "default") Microsoft uses Excel to open and edit, but it is not an Excel file, but rather a 2D array of (usually numeric) data separated by a character, usually a comma.
The article explorers quick and efficient ways to export data from Excel to CSV keeping all special characters and foreign symbols intact. The methods work for all versions of Excel, from 365 to 2007.
Comma separated values (CSV) is a widely used format that stores tabular data (numbers and text) as plain text. Its popularity and viability are due to the fact that CSV files are supported by many different applications and systems at least as an alternative import/export format. The CSV format allows users to glance at the file and immediately diagnose the problems with data, change the delimiter, text qualifier, etc. All this is possible because a CSV document is plain text and an average user or even a novice can easily understand it without any learning curve.
In essence, each CSV format saves data as comma-separated values but performs encoding in a slightly different way. For example, Mac uses a single carriage return () represented by \r for a line break, while Windows uses a combination of carriage return and line feed () represented by \r\n.
CSV UTF-8 (comma delimited). It is Unicode Transformation Format 8-bit encoding that supports many special characters, including hieroglyphs and accented characters, and is backward compatible with ASCII. This format is recommended for files that contain any non-ASCII characters since the classic CSV format destroys them.
Unicode Text (*.txt). This is a computing industry standard supported by almost all current operating systems including Windows, Macintosh, Linux and Solaris Unix. It can handle characters of almost all modern languages and some ancient ones.
When Excel data is to be transferred to some other application such as the Outlook Address book or Access database, the easiest way is to save your worksheet as a .csv file, and then import that file to another program.
In case your worksheet has any formatting, formulas, charts, shapes or other objects, you will be informed that some features in your workbook might be lost if you save it as CSV (Comma delimited). If that is Okay, click Yes to complete the conversion without the unsupported features.
Export Excel to CSV without destroying special charactersIf your spreadsheet contains some special symbols, smart quotes or long dashes (e.g. inherited from a Word document), foreign characters (tildes, accents, etc.) or hieroglyphs, the method described above won't work.
UTF-8 is a more compact encoding since it uses 1 to 4 bytes for each symbol. Generally, this format is recommended if ASCII characters are most prevalent in your file because most such characters are stored in one byte each. Another advantage is that a UTF-8 file containing only ASCII characters has absolutely the same encoding as an ASCII file.
UTF-16 uses 2 to 4 bytes to encode each symbol. However, a UTF-16 file does not always require more storage than UTF-8. For example, Japanese characters take 3 to 4 bytes in UTF-8 and 2 to 4 bytes in UTF-16. So, you may want to use UTF-16 if your data contains any Asian characters, including Japanese, Chinese or Korean. A noticeable disadvantage of this format is that it's not fully compatible with ASCII files and requires some Unicode-aware programs to display them. Please keep that in mind if you are going to import the resulting document somewhere outside of Excel.
Once you've decided on the format, the below instructions will walk you through the process.
How to convert Excel to CSV UTF-8Suppose you have a worksheet with some foreign characters, Japanese names in our case:
Note. Some simple text editors do not fully support all Unicode characters, therefore certain characters may be displayed as boxes. In most cases this won't affect the resulting file, so you can simply ignore this or use a more advanced text editor such as Notepad++.
Note. If your file is intended for use in another application where the UTF-8 format is a must, do not make any edits nor save the file in Excel as this may cause encoding problems. If some data does not appear right in Excel, open the file in Notepad and fix the data there. Remember to save the file in the UTF-8 with BOM format again.
As already mentioned, Excel's Save As command is only able to convert an active worksheet. But what if your workbook contains a lot of different sheets, and you wish to turn them all into separate csv files? The only alternative suggested by Microsoft is saving each sheet under a different file name, which does not sound very inspiring, huh?
The below code converts all worksheets in the current workbook to individual CSV files, one for each sheet. The file names are created from the workbook and sheet names (WorkbookName_SheetName.csv) and saved to the same folder as the original document.
Please keep in mind that the above code saves sheets in the CSV format. If there are any non-ASCII characters in your data, then you need to convert to UTF-8 CSV. This can be done by changing the file format from xlCSV to xlCSVUTF8. That is, you replace FileFormat:=xlCSV with FileFormat:=xlCSVUTF8.
Apart from the methods described above, there exist a handful of other ways to convert Excel sheets to CVS. Below, I will share a couple of my favorite ones.
Excel to CSV via Google SpreadsheetsThe use of Google Spreadsheets for .xlsx to .csv conversions seems a very simple workaround:
Note. If your original Excel sheet contains special characters, the resulting CSV file may not display the characters correctly when opened in Excel, though it looks perfect in many other spreadsheet programs.
I came across this solution on some forum, cannot remember which exactly. To be honest, this method has never worked for me, but many users reported that special characters, which got lost when saving .xlsx directly to .csv, are preserved if to save a .xlsx file to .xls first, and and then save .xls as .csv as explained in How to convert Excel to CSV.
Anyway, you can try this method of exporting Excel to CSV on your side and if it works, this can be a real time-saver.
Convert Excel to CSV using OpenOfficeOpenOffice is an open-source suite of six applications. One of them is a spreadsheet app named Calc, which is really good at exporting spreadsheet data to the CSV format. In fact, it provides more options (encodings, delimiters, etc.) than Microsoft Excel and Google Sheets combined.
I am searching for an easy way to just export the current sheet to csv, but keep my xlsx workbook intact. I frequently save as csv and forget to then save my workbook as xlsx and loose all of my work. Am I missing an easier way?
