Importing Multiple CSV Files Into One Workbook

Jun 15, 2013

I am troubleshooting my macro that seems to cause a data shift with the Letter "F" when I import multiple CSV files into one spreadsheet. When I go outside of the macro and record a macro and import the CSV into a workbook it works perfectly fine. But there must be something in this code that is causing the shift:

VB:
Private Declare Function SetCurrentDirectoryA Lib _
"kernel32" (ByVal lpPathName As String) As Long
Public Function ChDirNet(szPath As String) As Boolean
Dim lReturn As Long
lReturn = SetCurrentDirectoryA(szPath)

[Code] ....

I have attached an excel workbook that shows how the macro imports vs. a regular import. Why "F" is causing a shift in the data.

Importing Multiple CSV Files Into Workbook

Dec 3, 2012

I have a workbook that contains over 100 worksheets with stock data and price information. It uses a screenscraper to update the workbook each day with the latest day's price, and then exports each of these .csv files into a local directory. The macro for this is working. In effect it is generating a price history file automatically in my absence for me that can be read by charting software.

What I would like though is a macro to loopthrough and backfill missing price histories on each worksheet. I have a source of .csv price histories already, but would like to avoid having to cut and paste each of the 105 files manually, as it may become a regular occurence.

Each worksheet that requires backfilling has the stock code in the cell "A2", so that can be used to search for the filename Range("A2") & ".csv"

This is as far as I have got - however it results in a runtime error (91) Object variable or With block variable not set, pointing to this line:-

VB: Workbooks.Open Filename:="D:FinancialData SheetsSpreadsheetsPension" & Ws.Range("A2").Value & ".csv"

VB:
Sub BackFillData()
Dim Ws As Worksheet
For i = 1 To 105
'Sheets.Add
ActiveSheet.Name = "Fund" & i

[Code] ......

Importing Multiple Text Files Into One Workbook

Apr 26, 2007

I am using excel 2003. I have more than 500 text file which are result of some numerical analysis. I have another bunches of the same file number. I can record and play around with macro.

What I want to do is
-copy selected cells from imported text file in excel and paste in new or in first opened excel file. I have recorded macro for one file including importing from text to excell, copy and paste the selected file (look the macro below). But I have more than 500 files and I want to do the macro the same thing for each file in one excell file. Do i have to make one macro for each file??, that takes much more time than manual import and copy paste. The cell position and range to copy is the same, but have to be pasted in new row (in one excel summery file). The file name of each text file is different and all are in the same folder.

Sub text_to_excel()

Workbooks.OpenText Filename:= _
"I:ResearchVALERI_germinationvaleri_slopevaleri_slope_COREL_DHPoutputDSCN2589.txt" _
, Origin:=xlMSDOS, StartRow:=1, DataType:=xlDelimited, TextQualifier:= _
xlDoubleQuote, ConsecutiveDelimiter:=True, Tab:=True, Semicolon:=False, _ ..................

Importing Multiple Txt Files

Feb 27, 2008

I have part of macro to import a txt file into excel but it is not working as it should. It is giving me a message "This file is not a recognizable format" but its just a normal txt file. Also after it gives me this warning it will open in excel and with every new txt file it gives me this warning and after it opens it.

The code I am using is:

Sub su()
Dim oWbk As Workbook
Dim sFil As String
Dim sPath As String
sPath = "C:Historical" 'location of files
ChDir sPath
sFil = Dir("*.txt") 'change or add formats
Do While sFil "" 'will start LOOP until all files in folder sPath have been looped through Set oWbk = Workbooks.Open(sPath & "" & sFil) 'opens the file
Workbooks.OpenText (sPath & "" & sFil), Comma:=True, DataType:=xlDelimited
' do something
sFil = Dir
Loop ' End of LOOP
End Sub

In this line it gives me Runtime error 1004 Method 'Opentext' of object workbook failed:
Workbooks.OpenText (sPath & "" & sFil), Comma:=True, DataType:=xlDelimited

Importing Multiple Text Files

Apr 16, 2008

This is a great bit of code (I found), to import multiple text files.

I have one small issue -

currently it imports with each file going to a new column, like this: text file1 A1:A4, txt file2 B1:B4, txt file3 C1:C4 etc etc

And eventually i risk running out of columns because I'm working with a lot of text files.

Can someone tell me what to do to modify this code so it imports like this? :
text file1 A1:D1, txt file2 A2:D2, txt file3 A3:D3 ETC ETC

.e.g. first file imports across row1, second file across row2 etc


Sub test2()
Dim myDir As String, fn As String, ff As Integer, txt As String
Dim delim As String, n As Long, b(), flg As Boolean, x, t As Integer
myDir = "\BP1MELIS001SHARED_DATAEVERYONESolutions IntranetPriceMasterlogs" '

Importing Selective Lines From Multiple Text Files

Jun 18, 2009

I have many text files basically with the same data from different dates. I am trying to select specific lines from each text, one that includes ".txt" which is the date, ex: "2008_308" and one that includes the word "PIXEL" and the following 5 lines after that.

I found a very similar post to mine and someone provided the script using VB for the question. It works, but it was only for one text file. I would like to use it for multiple text files. The files are all dated, i.e. "2008_308.txt". Although some of the dates are missing.

This is the script, from another posting, for importing selective lines from one text file:

Sub test()
Dim fn As String, txt As String, delim As String, a() As String
Dim i As Long, ii As Long, iii As Long, n As Long, x, y
fn = "c: est.txt" ' İChange here (File Path)
delim = vbTab ' İChange here (delimiter)
temp = CreateObject("Scripting.FileSystemObject").OpenTextFile(fn).ReadAll
x = Split(temp, vbCrLf)
ReDim a(1 To UBound(x) + 1, 1 To 100)
For i = 0 To UBound(x)
If InStr(1, x(i), "txt", 1) > 0 Then
n = n + 1 : y = Split(x(i), delim)
For ii = 0 To UBound(y)
a(n, ii + 1) = y(ii)..........................

How To Get Multiple Cells From Multiple Files Into One Workbook

Jan 13, 2014

So, today my manager came to me and informed me that he wanted me to do a little data entry for him... WOW... So I have about 2000 invoices to go through(all excel files, in their dated folders... 12-2-2013(folder) and the filenames are 12-2-2013(1), 12-2-2013(2) etc.)

I need to take these individual files and have certain cells from each in certain cells of a new workbook for example...

file 12-2-2013(1)... I need cell C3 from that file to go to cell A2(and this will be the same for all the other files... 12-2-2013(2) cell C3 needs to be in A3 etc etc etc.. this is the sale date)
file 12-2-2013(1)... I need cell a15 and b15(they are both "stretched out" cells) to be put in C3 of the new workbook and so on.

is there an easy way/formula to do this all? I have to have this done by friday at the latest(tomorrow preferred @@) I have to input data for 7 cells...

Importing And Analysing Files

Nov 6, 2008

We have an online system that generates xls dump files. These essentially contain a table with lots of information about every test case we perform. From this table I am interested in three fields: TestID, Location and TestCaseStatus. With these fields I need to generate : A drop down menu to filter by location
A table containing the count of each test case status for the relevant location. Every Row represents a TestID and the columns a status.

I was hoping you would be able to give me an idea of a good way to tackle this. My initial thought is that SQL maybe useful to import the desired table columns and then further filtering would have to be done through nested for loops. I'm sure you can suggest a better way though.

Also, if possible, I would prefer the raw data not to be displayed in my analysing spreadsheet - only the summary should be shown.

Importing Text Files

Sep 25, 2002

I have a whole lot (hundreds) of .txt files that contain fixed width data that I need to convert to Excel format. I can open each file and step through the Text Import Wizard, then save it as an .xls file, but I'm wondering if there's a way to convert all the files in a given folder from .txt to .xls without having to open each one while (here's the kicker) still placing the data between the spaces on the .txt file into individual cells and columns like the wizard does.

Importing CSV Files In A Worksheet

May 25, 2009

The Excel 2007 help menu claims that you can open a CSV file directly into a worksheet but I always get all the fields clumped-up into the first column.

After many tribulations I was able to import it through the Data import menu (text).

Could someone explain what I am doing wrong with the first method described above. It appears that the CSV converter is not working properly on my computer.

Combine Multiple Files Into One Workbook (single Worksheet)

Apr 12, 2007

I've pieced together code from a number of solutions on the forum and figured out how to find the files I need to process, but can't seem to figure out the code to actually combine/append each worksheet into a single one. I've searched the "sea of options" on this forum and managed to do one thing well. Pardon all my notes embedded in the code below, but if I don't do it that way, I'll only confuse myself further (which is easily accomplished) ... or lose my notes!

I’m going to run this code from an add-in menu, which is already created and working (yeaah!) … so (I think) I need to have the code either create a file named "Master (Combined).xls" in the target folder ... or ... have a file already created in MYFOLDER and have this code delete all but the header row when the file is opened(???) The "Master (Combined).xls" workbook needs to consist of one worksheet named "Master". I want it to open the current workbook (.foundfiles(i)), select all the data, and append it to the master workbook on the "Master" worksheet (sheet 1). The Master Worksheet in the Master Workbook needs to start out as a blank sheet ... except for the header row. I can add code to put the headers in at the start, if necessary

Sub g_CombineMultWB_AllXLSFiles()
' This Will combine all XLS files located in the
' S:DMSMSPOMSMaster POMS NIIN DataMaster EMALL Data FilesEMALL Excel Folder
' into a single worksheet in a newly created (or previously existing) workbook
'
' LOCATION OF FILES (ACTUAL):

Dim i As Integer
Dim wbResults As Workbook
Dim wbCodeBook As Workbook
Application.ScreenUpdating = False

Excel 2003 :: Deleting Rows For Multiple Files In Separate Workbook

Sep 10, 2012

I'm new to this forum and to VBA

First-off, I'm using Excel 2003 SP3.

The setup: A software application I regularly use produces csv data files (in this case approx 300 files). These I have converted to xls format using a separate macro. The files are in one folder and named as follows eg

G1 18800.xls
G1 18802.xls
G2 18975.xls
G3 19881.xls
G3 19990.xls
G5 19990.xls
etc

The files contain the following data:

DATE TIME VALUE STEPS EXCL ACCEL
01-Oct-03 08:00 0 0 FALSE 0
01-Oct-03 08:01 0 0 FALSE 0
01-Oct-03 08:02 0 0 FALSE 0
01-Oct-03 08:03 0 0 FALSE 0
01-Oct-03 08:04 757 20 FALSE 0.18
01-Oct-03 08:05 1714 32 FALSE 0.44
01-Oct-03 08:06 1524 32 FALSE 0.39
01-Oct-03 08:07 1665 45 FALSE 0.47
01-Oct-03 08:08 1644 42 FALSE 0.46
01-Oct-03 08:09 263 8 FALSE 0.06
etc

I then created a macro using code I sourced from the internet, and included some addtional commands (filename, copy/paste). See below. This macro opens the all the xls data files in the folder and copies the relevant data to an analysis workbook [Analysis sheet, Results sheet, Master sheet] ie the data is copied from the data file and pasted into the Analysis worksheet. Then the results are copied from the Results sheet to the Master sheet. So far so everything works.

My problem is this: I'm stumped at how to delete rows from the xls data files before running the analysis workbook and macro. In other words, after converting the csv files to xls format I need to clean the xls data files.

I have a separate xls file with criteria data in two columns:

FileName Date
G1 18800 06-Oct-03
G1 18801 02-Oct-03
G1 18801 03-Oct-03
G1 18801 05-Oct-03
G2 18795 14-Oct-03
G2 18795 15-Oct-03
G2 18795 16-Oct-03
G2 18795 17-Oct-03
etc

The rows in a particular data file, with dates that are not present in the Criteria workbook must be deleted. This to be done for every data file in the folder. Also, I need to exclude rows for specific time periods eg 12H00AM - 04H00AM from all the files irrespective of date.

the code needed [should a separate macro be run or can code be placed within the present macro?]. I've tried looking for something similar on the internet, but my requirements seem too customized to be able to adapt the code that I found. And of course this is waaaay above my present skill level!

Option Explicit

Sub CopyPaste()

'This code opens up data files (xls) in a specified folder and copies data A1:G17281 to an Analysis workbook (Analysis sheet).

'The data from the Results sheet is then copied to the Master sheet.

Dim wkbDest As Workbook
Dim wksDest As Worksheet
Dim wkbSource As Workbook
Dim wksSource As Worksheet
Dim MyPath As String
Dim MyFile As String
