CSVFileView is a simple CSV file viewer/converter utility that allows you to easily view the content of CSV or tab-delimited file created by NirSoft utilities or by any other software, in a simple table viewer. You can sort the lines according to one of the fields, remove unwanted fields and change their order, and then save the result back into CSV file, tab-delimited file, XML file, or HTML report.

Known Limitations

  • CSVFileView cannot load extremely large csv files.

Versions History

  • Version 2.20:
    • Added 'Display Filter' option (F2). The display filter is somewhat similar to the SQL WHERE clause, for example... The following filter will instruct CSVFileView to display only lines with 'Yes' value in the Connected column and the 'Device Name' column contains a 'USB' string:
      Connected = 'Yes' AND 'Device Name' CONTAINS 'USB'
    • Added 'Load Filter' option to the 'Advanced Open' window. It's similar to the 'Display Filter' feature, but instead of filtering the file after it's already loaded , the load filter skip items during the loading process, so the file will be loaded faster and CSVFileView will consume less memory.
    • Added 'First line contains column names' and 'Automatically detect the delimiter and quotes characters' options to the 'Advanced Open' window.
    • Added /aload command-line option, for loading a file according to the 'Advanced Open' settings.
    • You can now specify any variable inside the CSVFileView.cfg file as a command-line parameter, for example... In order to turn off the 'First Line Contains Column Names' option:
      CSVFileView.exe /FirstLineColumnNames 0
  • Version 2.16:
    • CSVFileView now displays an error message in the status bar when it fails to open a file.
  • Version 2.15:
    • Added option to save the text/xml/csv/html files in UTF-8 (Options -> Unicode/Ascii Save Mode -> Always UTF-8 )
  • Version 2.10:
    • Added 'Enable String Interning' option. When it's turned on, CSVFileView tries to detect repeating column values, and store them in memory only once, instead of multiple times. This option can be useful if you load a large file with many repeating strings, because the memory consumption of CSVFileView will decrease dramatically. However, the loading process will be slower than normal.
    • Fixed issue: When loading a large file, some actions, like selecting items and copying selected items to the clipboard were very slow.
    • When the 'After Loading File - Sort By' option is set to 'Original File Order', the loading process will be faster. (In previous versions, CSVFileView called the sort function when it's not really needed...)
    • Added 64-bit version.
  • Version 2.06:
    • Added /sort command-line option (For using with the save command-line options - /stab, /scomma, /shtml ...)
  • Version 2.05:
    • Added option to export to JSON file.
  • Version 2.02:
    • Added 'Add Byte Order Mark To Unicode Files' option. If you turn it off, CSVFileView won't add Byte Order Mark (BOM) when saving to Unicode file.
  • Version 2.01:
    • Fixed bug: CSVFileView failed to remember the last size/position of the main window if it was not located in the primary monitor.
  • Version 2.00:
    • Added new file type in 'Save Selected Items' option: Custom Delimited File. You can set the desired delimiter and quote characters of this file type using 'Custom Delimited File Settings' (Ctrl+F9)
    • Added 'Always On Top' option.
  • Version 1.96:
    • Added secondary sorting support: You can now get a secondary sorting, by holding down the shift key while clicking the column header.

Using CSVFileView

CSVFileView doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - CSVFileView.exe
After running CSVFileView, you can open the desired CSV/Tab-Delimited file by using the 'Open CSV\Tab-Delimited File' option (Ctrl+O) or by dragging the file from Explorer into the main window of CSVFileView.
If the first line of the CSV/Tab-Delimited file doesn't contain the column names, you should turn off the 'First Line Contains Column Names' option (Under the Options menu) before opening the file.

After opening the desired file, you can do the following actions:

  • Sort the lines by one of the fields, simply by clicking the right column header. If the column values are numeric, CSVFileView automatically makes a numeric sorting instead of string sorting.
  • Remove one or more columns or change their position by using the 'Choose Columns' window (F7). You can also change the position of the columns by dragging the column headers into another position.
  • Select one or more lines, or select all lines (Ctrl+A), and then saving them into csv, comma-delimited, XML, or HTML file, by using the 'Save Selected Items' option (Ctrl+S). You can also press Ctrl+C to copy the selected lines into the clipboard, and then paste them into Excel.

More Options

  • Unicode/Ascii Save Mode: By default, CSVFileView saves all files in Unicode, except of csv file, which is saved as Ascii. The reason for saving csv files as Ascii is... Microsoft Excel. That's because Microsoft Excel doesn't open properly csv files that are saved as Unicode.
    You can change the default behavior, by going to Options -> Unicode/Ascii Save Mode, and then choosing the desired save mode - Ascii or Unicode.
  • Add Header Line To CSV/Tab-Delimited File: When this option is turned on, and you export the selected lines into csv/tab-delimited file, the first added line contains the column/field names.
  • First Line Contains Column Names: When this option is turned on, CSVFileView uses the first line of the opened csv/tab-delimited file as the column names list.
  • Automatic Numeric Sorting: When this option is turned on, CSVFileView automatically uses numeric sorting when numeric values are detected.

Using Filters

Starting from version 2.20, CSVFileView allows you to apply a filter for viewing only the lines you need.
There are 2 places that you can use filter:
  • Display Filter window (F2): The Filter is applied after the entire file is already loaded. When using this option, you can easily remove the filter and view again all items by switching the 'Use Display Filter' option (Ctrl+F2) or you can press F2 again and use another filter.
  • 'Advanced Open' window (Load Filter): The filter is applied while loading the file, so all lines that are filtered out by your filter are not loaded at all. If you filter out a lot of lines with the load filter, then the file will be loaded much faster and CSVFileView will consume less memory.

A filter string of CSVFileView is somewhat similar to the SQL WHERE clause. CSVFileView currently supports the following operators:

Here's some examples and rules for using the CSVFileView filters:

  • The following filter instructs CSVFileView to display only items with 'Yes' in 'Connected' column and 'No' in 'Disabled' column:
    Connected = 'Yes' And Disabled = 'No'
  • Display only items with value different than 'Yes' in 'Connected' column and with 'SerialNumber' column begins with '12' string:
    Connected != 'Yes' And SerialNumber BEGINSWITH '12'
  • Display only items the their Filename column begins with 'f' and has more 7 characters (You can use ? and * in LIKE operator, like the wildcard of Windows):
    Filename LIKE 'f???????'
  • Display only items the their Filename column contains 'abc' string or 'qwe' string.
    Filename CONTAINS 'abc' OR Filename CONTAINS 'qwe'
  • When a column name has a space character, you must put it in quotes, for example:
    'Device Name' CONTAINS 'USB'
  • When there are no column names, you can use 'Column1' as the first column, 'Column2' for the second column, and so on... For example:
    Column1 LIKE '??34*' and Column4 = 'Yes'
  • You can use the NOT operator to reverse the result, for example... This filter will display items that don't contain 'txt' string in the Filename column:
    Filename NOT CONTAINS 'txt'
  • You can use the   >   <   >=   <=   operators with numeric values in order to filter by a range of numbers. For example, in order to display only records with ID value between 100 and 200:
    ID >= 100 and ID <= 200
  • When mixing and/or in the same filter, you must use parentheses, for example:
    (Column1 = '3' AND Column4 = 'No') OR (Column1 = '4' AND Column4 = 'Yes')

You can also apply a load filter from command-line by using /aload with other command-line options to set the 'Advanced Open' settings, for example:
CSVFileView.exe /AutoDetectChars 1 /UseLoadFilter 1 /LoadFilterStr "Column1 LIKE 'a*' " /aload C:\temp\myfile.csv
CSVFileView.exe /AutoDetectChars 1 /UseLoadFilter 1 /LoadFilterStr "Column1 = 'Yes' and Column2 = 'No' " /aload C:\temp\myfile.csv /scomma c:\temp\filtered_file.csv

Opening Web Server Log File

With CSVFileView, you can also open a log file of Apache or other Web server that generates a log file in the same format. In order to do that, you should turn off the 'First Line Contains Column Names' option, open the 'Advanced Open' window (Ctrl+Shirt+O), type \s (space character) in the delimiter field, and "[] in the quotes field. Choose the log file to open and then press Ok.

Command-Line Options
