Salutari,
Am nevoie de ajutor cu importul unor date in Excel. Problema este urmatoarea: Am un fisier .txt de genul 15 100 50 85 5.7 1 2.9 6 8.01 8 9 4 10 5 8.5 (rand liber) 8 9 5 7 44 sunt aproximativ 2 milioane de randuri. Cum export aceste date in excel in formatul: primul rand: 15 100 85 1 6 8 4 5 (fiecare numar in coloana lui de la A la H ignorand al doilea numar (50 5.7 2.9 8.01 etc) sau daca e mai usor urmate de al doilea numar in alte coloane) (se poate edita excelul mai tarziu) al 2 rand: urmatoarele 8 numere al 3 rand: urmatoarele 8 numere etc etc |

banuiesc ca ce ai tu acolo sunt niste parametri.
tu ai dori sa-i asezi cate 8 tot ar rezulta un sfert de milion de randuri(caz in care excelul va crapa sigur) chiar din momenrul importuluid e date, nu mai spun de o eventuala prelucrare a datelelor ulterioara acestui import. poti face rapid un test. deschide fisierul .txt, Ctrl+A deschide un excel si da-i paste, sa vezi ce se intampla. opinia mea este sa-ti cauti o alta modalitate de prelucrare a acelor date Edited by nexusm, 17 July 2015 - 11:53. |

In locul tau, as importa in Word si as inlocui fiecare spatiu cu tab (^t). Asta ti-ar aduce al doilea numar pe a doua coloana, pe care apoi ai putea sa o stergi (fie dupa import in Excel, fie, cum as face eu, transormand intai textul in tabel inca din prelucrarea in Word)

Ai nevoie doar de data asta sau va fi ceva frecvent?
Se poate face in orice limbaj care stie sa lucreze cu fisiere text. Salvarea o poti face ca CSV si astfel ajungi si la Excel fara vreo librarie anume (daca nu crapa Excelul incercand sa deschida fisierul ) |

#sorin147 la ce program te gandesti.
Am nevoie doar de data asta. Eu deja ma gandeam sa fac un program in Mathlab. |

Daca ma plictisesc suficient de mult in seara asta la munca si nu am treaba, ii dau o incercare. N-ar strica daca as avea si documentul, asta daca nu contine ceva date deosebite.

http://www.cpearson....rtbigfiles.aspx Complete VBA Code Option Explicit Option Compare Text '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ' modImportBigFiles ' This module contains the ImportBigTextFile procedure and the IsFileOpen procedure. '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' Sub ImportBigTextFile() ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ' ImportBigTextFiles ' By Chip Pearson, [email protected], www.cpearson.com ' This procedure is on http://www.cpearson....ortBigFiles.htm ' This procedure requires Excel 2000 or later. ' ' An Excel worksheet (2003 and earlier) is limited to 65,536 rows. You cannot increase this ' limit. Therefore, if you use Excel's tools to import a text or csv file with more ' than 65,536 rows of data, Excel will only import the first 65,536 records (or fewer, ' depending on the row in which you start the import). This procedure may be used to import a text ' or CSV file of any number of rows. It will begin the import by placing the imported data on the sheet ' named in C_START_SHEET_NAME starting in row C_START_ROW_FIRST_PAGE. ' ' Note that the import process always writes records to the ActiveWorkbook, which may or may not ' be the same workbook that contains this code. Ensure that the proper workbook is active ' prior to running the import process. ' ' RowNdx is the current row number where the input record will be placed. When any one or more ' of the following are true: ' RowNdx > Rows.Count ' RowNdx > LastRowForInput ' RowsThisSheet > MaxRowsPerSheet ' the procedure will create a new worksheet immediately following the current worksheet and ' name it ' C_SHEET_NAME_PREFIX & Format(SheetNumber, "0") ' ' The procedure will optionally split the input data into multiple columns, delimited by a ' character specified in the SplitChar variable. ' ' The following constants and variable determine how the procedure handles data and new worksheets: ' ' C_START_ROW_FIRST_PAGE is the row number on the first worksheet (C_START_SHEET_NAME) ' where the data should be placed. This is used if you have ' header rows that you want to preserve. ' ' C_START_ROW_LATER_PAGES is the row number on subsequent (sheet 2, 3, etc) that the ' data should be started. ' ' C_START_SHEET_NAME is the name of an existing worksheet. The imported data will ' start by filling this sheet before creating a new worksheet. ' ' C_START_COLUMN is the column in which the data is placed. If SplitChar is ' vbNullString, the entire line of input data will be placed ' in this column. If SplitChar is not vbNullString, the input ' data is split into an array using SplitChar as a delimiter, ' and each data element will be put in its own column, starting ' with C_START_COLUMN. ' ' C_TEMPLATE_SHEET_NAME is the name of an existing worksheet that is used as the ' template for each new sheet created by the function. This ' must NOT be the same as C_START_SHEET_NAME, since copying ' C_START_SHEET_NAME would copy all of the imported (so far) ' data to the new sheet. If you don't want to use a template ' sheet, set this constant to vbNullString. ' ' C_UPDATE_STATUSBAR_EVERY_N_RECORDS ' is the number of records after which the a message will ' be displayed in the StatusBar. Set this value to <= 0 if you ' do not want any StatusBar updates. A typical value for this ' constant is 1000. ' ' C_STATUSBAR_TEXT is the text to be displayed in the StatusBar. The current record ' count will be appnded to this text. This value is not used ' if C_UPDATE_STATUSBAR_EVERY_N_RECORDS is <= 0. The string ' value in this constant should include a trailing space. A ' typical value for this constant is "Processing Record: " ' ' C_SHEET_NAME_PREFIX is a string value which will be used for naming newly created ' worksheets. This constant must have <= 28 characters, which ' leaves the procedure three characters for the numeric suffix. ' This allows for importing 65,404,928 rows. If there are more ' rows, the proceudre will import them, but the worksheet names ' may not be named properly. They will, however, be in the proper ' sequence. ' ' LastRowForInput is the last row number on a worksheet that the imported data ' should be placed. Set this to either <= 0 or to Rows.Count ' to import data to the last row of the worksheet. ' ' MaxRowsPerSheet is the maximum number of rows to import on to a single worksheet. ' Set this to <= 0 or Rows.Count to import to the last row ' of a worksheet. While the procedure can properely handle values ' in both LastRowForInput and MaxRowsPerSheet, you will most likely ' set both to <=0 or set one to <= 0 and the other to its appropriate ' value. Typically, both variables will not have non-zero values. ' ' SplitChar is the character which delimits the data fields in the input data. ' If this character is vbNullString, the entire input line of data ' will be placed in C_START_COLUMN. If SplitChar is not vbNullString, ' it is truncated to 1 character (the left-most character) and then used ' in Split function to split the input data into an array, delimited by SplitChar. ' Each element of the array is put into its own column, starting with ' C_START_COLUMN and proceeding to the right. SplitChar is typically set ' to a comma, semicolon, or vbTab, but it can be any character. ' ' The procedure saves the following Application properties, then turns them off. It will restore the saved ' values at the end of the procedure. ' Calculation ' ScreenUpdating ' DisplayAlerts ' EnableEvents ' '------------------------- ' Possible Data Loss '------------------------- ' It is possible that some data loss may occur if the function is splitting the input data into multiple columns. ' If the number of data elements in the input record plus the value of StartColumn is greater than the number ' of Columns in the worksheet, data elements that would go past the right-most column of the worksheet are not imported. ' The number of these truncated records is stored in the TruncatedCount variable and is displayed at the end ' of the procedure.
