File Too Big...way To Parse Out Data And Write To Csv
Feb 12, 2010
I have a file with multiple tabs of data...lot's of data (each tab has 80,000+ lines and 23 columns...3 are formulas, the rest is imported data). I've brought Excel to it's knees (i.e. crashes). Yes, I'm using 2007.
What I'm trying to do is extract 6 cells of data from every 10th line and write it out to a CSV file with two more pieces of information (same for each line).
What I was doing was creating a separate worksheet for each one to be extracted, parsing out the data, and then copying that data to yet another workbook that was then saved as a CSV.
First, in retrospect, that was a waste of time. Second, the addition of the extra worksheets to do the parsing was crashing Excel due to the extreme size of the workbook.
What I'd like to do is use a macro to do all of this in one swell foop:
1) Prompt me for a file name (or I can put the desired name in a cell and read it from there if that simplifies the code)
2) Open a new text file with that name and ".csv" extension in the same folder as the original workbook
3) Write out the column headers: (Fix, Satellites, Lat, Lon, alt (ft), Date, utc_t, course)
4) Step through each row, looking at the text contents of column B (looks like 22:50:07.100)...if it ends in ".000" do the following:
4a) write "PPS,4," to the open text file
4b) write the cell contents from columns "V", "W", "J", "C", "B", and "L" to the text file in the exact format they appear in the text cell.
The output file should look like (very short example):
I have a text file with no discernable format ( can't import into excel) that is too large to put all the data into an excel worksheet. This file is made to print out on a network printer.
I don't need all the info in the file, I would like to specify a variable, search the text file for the variable, then specify the amount of rows down to look for the data value and input the result into an excel spreadsheet.
In theory it seemed fairly simple to loop through a sheet and write before and after each cell, but once I tried writing the code I realized I was in way over my head.
I have the data to import / read in a pdf, in a doc, or in an Excel worksheet whichever is easier to use. I need to import the data, parse it into the correct cells for that row and then repeat the import until the end of the file. Not all the cells are in each group of data to import, so those cells will be null for that row. Some of the data for one cell may be in up to 14 lines in the data file. I have be concatenating these data rows into one cell. There are 48,000 lines in the file to import or I would do this manually. I am assuming that doing this in VBA would be the most efficient method.
I need 3 columns - Title - HD - Channel. If no value for HD, the field would be blank.
Data looks like this in txt file: > A&E HD 265 > ABC Family HD 311 > Altitude Sports and Entertainment HD 681 > American Movie Classics (AMC) 254 > Animal Planet HD 282 > BBC America 264 > BET Jazz 330 > BYU TV 374 > Big Ten Network HD 220 > Black Entertainment Television (BET) 329 > Bloomberg Television 353 > Boomerang 298
Needs to look like this in Excel > Should look like: > A&E HD 265 > ABC Family HD 311 > Altitude Sports and Entertainment HD 681 > American Movie Classics (AMC) 254 > Animal Planet HD 282 > BBC America 264
I have a software application that imports audio files and writes information about these files to text files. I'm trying to write and Excel/VBA application that will parse and import the data contained in these files. find a sample of one of these files attached. The big hurdle I am facing is I cannot figure out how to parse this file - the delimiter keeps changing as throughout the file (see example below):
Is it possible to write vba code that will generate a text file with ALL changes that were made to an excel file. Ex. If Cell A17 = "Monday, June 4, 2012" and a user updates Cell A17 to "N/A", I would like to know what the value was before and after the udpate was made.
I receive a flat text file every week which I would like to grab with excel and extract only the data I need and enter the data into separate cells and loop until I reach the end of the flat file. I got a subroutine written that allows me to open my text file and it will enter all the data however I need to know how to parse only the stuff I need and enter it into the right cells and loop until I reach the end of my text file. Here is what I have so far:
Sub testFSNew() Dim fs As Object ' scripting.filesystemobject Dim txtIn As Object ' scripting.textstream Dim strFile As String 'File Name Dim strLine As String 'Current line being read.
[code].....
Now so far this opens the text file and dumps all the data into an excel spreadsheet however when I say all I mean it dumps everything into the first cell and does not separate it, the following is an example of the text in the flat file. I will only put in the first 5 rows because their is 5000 rows in the real file.
Ok so the first problem is I don't need the first line it's a header line and if you will notice everyline of the file ends with either a 5 or a 4 but it is information about each employee, so the next line would end in a 5 and that would be the beginning of the next employee.
P.S. I noticed in the preview post that this message board truncated my flat file data, so keep in mind that each line is indeed 1 line ending in either 5 or a 4
I have a CSV file that contains data in columns A-Q. Some cells may be blank.
I'm having trouble opening this CSV file because when I re-save it after editing it, Excel removes any quotes that were around the data.
Here is the criteria that the data must be formatted like:
If the value in column A = "H", the following columns need quotes around the cell - A-F, H-I, K-M, P-Q. The values in the rest of the columns do not need quotes. If the value in column A = "D", the following columns need quotes around the cell - A-D, F, I-O, Q. The values in the rest of the columns do not need quotes. Data is only in columns A-Q.
Can somebody write a macro that will format the data as list above and save?
I'm getting an object required error in excel, but don't really understand.
rivate Sub CommandButton1_Click() free_number = FreeFile() Filename = app.Path & "/file_write_output.txt" StringToSave = Cells(1, 1).Value Open Filename For Output As free_number Write #free_number, StringToSave Print #free_number, StringToSave Close #free_number End Sub
I'd like to use Excel VBA to write this meta tag into that HTML file:
****** http-equiv="refresh" content="600"> That's to make it refresh every 600 seconds.
The most elegant way would be to locate the "head" tag and write it right after it, but the refreshing meta tag seems to work where ever it is, even at the very end of the file after the "/html" tag! So locating the "head" tag is not that important, if it's difficult.
So, how do I use VBA to write lines into a HTML (or any text) file?
The problem with the Write macro was that, although it did work, it used SendKeys which has to be slowed down considerably.
Here is a new version of the Write macro that works as normal. I originally tried to use CDDBControl.dll version 1.2.0.51 which is widely available on the internet but found that I could only get it to change 1 file before crashing Excel.
I have put the READ macro in the next message.
Dim ws As Worksheet Dim FromRow As Long Dim LastRow As Long Dim FilesToChange As Integer ' number of files to change Dim FilesChanged As Integer ' number of files changed Dim MyFilePathName As String ' full path & file name Dim MyFileType As String ' mp3 wma etc. '- Dim id3 As Object Dim MyArtist As String Dim MyAlbum As String Dim MyGenre As String Dim MyTrack As String Dim MyTitle As String
Sub WRITE_TO_EXPLORER() Application.Calculation = xlCalculationManual Set ws = ActiveSheet Set id3 = CreateObject("CDDBControlRoxio.CddbID3Tag") LastRow = ws.Range("A65536").End(xlUp).Row ' count worksheet rows FilesToChange = ws.Range("A2:A" & LastRow).SpecialCells(xlCellTypeVisible).Count If FilesToChange = 0 Then MsgBox ("No files to change."): Exit Sub FilesChanged = 0........................
I have a tool that accesses a master sheet. Multiple people use the tool (sort of a user interface).
In some cases I need to write to the Master in which I check to make sure its not read only when the macro opens it (that works fine).
In other cases, like when just pulling information, read only is fine. But, I have not specified read only when I open the master. Sometimes the users are getting a "File Now Available" with a read-write and cancel option. I do not want them to get this message.
My current universal call to master looks like this: ...
I have a command that opens up another workbook. This workbook is sometimes open on another computer, so that the book opens up on my computer in write-protected mode (shows in the top of the window). Usually, when opening other books through the Excel functionality, a message box appears if the file is open and warns that the file is in use by another user. However, with the code I have at the moment, this is not the case when I try to open with my command. See code below:
Private Sub cmdOpenBook_Click() 'Open book ChDir "I:DevelopmentSpecialUtvikling" Workbooks.Open Filename:= _ "I:DevelopmentSpecialUtviklingJointApp.xls" End Sub
Is there any way of displaying a msgbox warning when opening another file through VBA?
I need some VBA code to cycle through each and every folder and file in a given root directory and write the file name string to a cell. (does not need to look at the content of sub-folders only the names of all objects sitting directly under the given root.)
I'm looking for a worksheet function that will allow me to separate into another cell the characters between the second and third slash in the source cell. The number of characters varies, but the value I want is always between the second and third slash.
I have recorded (i.e. manually as opposed to writing VBA code) a number of macros to perform a routine, however they do not work when I change the filename.
Could someone please advise on how to edit these macros (which reference a specific filename) so that they work when the file name is changed. The macros copy and paste values from different worksheets and then run another set of macros. However all macros and worksheets are located within one excel file
In VBA, is it possible to write to a text file, on 1 single line (without carriage return or line feed) the values of a dynamic array? For instance, I have the array:
Dim my(n) As Double 'n is changeable my(0) = 0 my(1) = 1 my(2) = 2 .....
I want to write to a text file, like this: Write #filename, my(0), my(1), my(2) '..... until my(n) but n is changing
I want them on 1 line, because I use the other direction (up - down) for other things).
I have a PDF document with an income statement that I'm trying to bring into excel. When I copy it, it puts all of the information in 1 column like this: NET INCOME 183,450 (237,660) 421,110 177 (1,461,273) (1,769,800) 308,526 17 CAPITAL EXPENDITURES Land Improvements 0 0 0 35,000 0 (35,000) Building Improvements 7,500 0 (7,500) 243,129 626,500 383,371 61. I cannot use text to columns, because the CATEGORIES are different in length (3 to 4 to 5 words at times).
I can seperate the numbers from the words, but I can't seperate the numbers from one another. Is there any way that I can do this via a text fuction?
