I have an excel created from a comma-delimited text file originally from a .sql file with an SQL INSERT query.
In one of the columns I have: "Cast(0x123456AB...) As TIME
Obviously this is NOT the jsondate format... so no help from that question...
I replaced the Cast( and replaced the ") As TIME" with empty strings.
So now I have the time values in hexadecimal.
How do I convert them into Excel Time or Datetime?
OK Playing around with it showed me that it's exactly the same as the jquery date answer. You take the numeric portion starting with 0x.
Take the 10 digits AFTER the 0x. e.g. in A2: =MID(A1, 3, 10)
Turn it into hexadecimal e.g. in A3: = HEX2DEC(A2)
Divide by 86400 e.g. A4: =A3/86400
And add the result to 1/1/1970 date. e.g. = A5: =A4 + Date(1970, 1, 1)
Or in short:
=(hex2dec(mid(a1,numstart,10))/86400) + date(1970,1,1)
Replace numstart with the 1-starting index of the number.
e.g. 3 if you have a 12 or 13 digit number like 0x12345678AB and you'll get 12345678AB
This is similar to the Convert JSON Date /Date(1388624400000)/ to Date in Excel
Except that:
a. The question was answered wrong and wouldn't work. (I edited it)
b. The .sql file was retrieved in a stored procedure from the database via SQL. While in the question they were using jquery returned ajax data, which seemed to differ. Turns out they're the same number with a different format.
As an added remark, I had a space mark at the beginning of my hex number. Until I did the MID on it, I didn't see that.
Note: When using ajax returned formatted dates like /date:0x12345678ab/ you'll set numstart to 8. If hex2dec fails, try turning the hex string into uppercase
before calling hex2dec. To debug just put each formula in a separate cell, so you see what works and what doesn't.

So I have some code that does essentially this:
REAL, DIMENSION(31) :: month_data
INTEGER :: no_days
no_days = get_no_days()
month_data = [fill array with some values]
WRITE(1000,*) (month_data(d), d=1,no_days)
So I have an array with values for each month, in a loop I fill the array with a certain number of values based on how many days there are in that month, then write out the results into a file.
It took me quite some time to wrap my head around the whole 'write out an array in one go' aspect of WRITE, but this seems to work.
However this way, it writes out the numbers in the array like this (example for January, so 31 values):
0.00000 10.0000 20.0000 30.0000 40.0000 50.0000 60.0000
70.0000 80.0000 90.0000 100.000 110.000 120.000 130.000
140.000 150.000 160.000 170.000 180.000 190.000 200.000
210.000 220.000 230.000 240.000 250.000 260.000 270.000
280.000 290.000 300.000
So it prefixes a lot of spaces (presumably to make columns line up even when there are larger values in the array), and it wraps lines to make it not exceed a certain width (I think 128 chars? not sure).
I don't really mind the extra spaces (although they inflate my file sizes considerably, so it would be nice to fix that too...) but the breaking-up-lines screws up my other tooling. I've tried reading several Fortran manuals, but while some of the mention 'output formatting', I have yet to find one that mentions newlines or columns.
So, how do I control how arrays are written out when using the syntax above in Fortran?
(also, while we're at it, how do I control the nr of decimal digits? I know these are all integer values so I'd like to leave out any decimals all together, but I can't change the data type to INTEGER in my code because of reasons).
You probably want something similar to
WRITE(1000,'(31(F6.0,1X))') (month_data(d), d=1,no_days)
Explanation:
The use of * as the format specification is called list directed I/O: it is easy to code, but you are giving away all control over the format to the processor. In order to control the format you need to provide explicit formatting, via a label to a FORMAT statement or via a character variable.
Use the F edit descriptor for real variables in decimal form. Their syntax is Fw.d, where w is the width of the field and d is the number of decimal places, including the decimal sign. F6.0 therefore means a field of 6 characters of width with no decimal places.
Spaces can be added with the X control edit descriptor.
Repetitions of edit descriptors can be indicated with the number of repetitions before a symbol.
Groups can be created with (...), and they can be repeated if preceded by a number of repetitions.
No more items are printed beyond the last provided variable, even if the format specifies how to print more items than the ones actually provided - so you can ask for 31 repetitions even if for some months you will only print data for 30 or 28 days.
Besides,
New lines could be added with the / control edit descriptor; e.g., if you wanted to print the data with 10 values per row, you could do
WRITE(1000,'(4(10(F6.0,:,1X),/))') (month_data(d), d=1,no_days)
Note the : control edit descriptor in this second example: it indicates that, if there are no more items to print, nothing else should be printed - not even spaces corresponding to control edit descriptors such as X or /. While it could have been used in the previous example, it is more relevant here, in order to ensure that, if no_days is a multiple of 10, there isn't an empty line after the 3 rows of data.
If you want to completely remove the decimal symbol, you would need to rather print the nearest integers using the nint intrinsic and the Iw (integer) descriptor:
WRITE(1000,'(31(I6,1X))') (nint(month_data(d)), d=1,no_days)
I have a csv file, the one from https://www.kaggle.com/jolasa/waves-measuring-buoys-data-mooloolaba/downloads/waves-measuring-buoys-data-mooloolaba.zip/1. The first entries look like this:
The first column has dates which I'm trying to read with this command:
matrix = dlmread ('waves-measuring-buoys-data/WavesMooloolabaJan2017toJun2019.csv',',',1,0);
(If referring to file on Kaggle, note that I slightly modified the directory and file names for ease of reading)
Then when I check a date by printing matrix(2,1), I get 1 instead of 01/01/2017 00:00.
How do I get the correct format?
csvread is only for numeric inputs.
Use csv2cell from the io package instead, to obtain your data as a string, and then perform any necessary string operatios and conversions accordingly.
I have grabbed from a file source a column that suppose to be a DATE not more longer than 8 chars in a NVARCHAR(50) staging field. Now when I try to cast it to DATE it fails because SQL is not able to apply the transformation.
I tried to go deeper and understand what's going on and take a look the length. Among the remarkable things I realized that the len is always 9 and has at the end in VARBINARY 00D00. I added manually a new row how suppose to came the field and the len fit as I expect.
code:
SELECT [LastPriceChange],len([LastPriceChange]),
convert(varbinary(max),[LastPriceChange])
FROM [STAGING].[MBEW]
group by [LastPriceChange]
order by 2 desc
Output:
I'm trying to get the final part to understand what is that thinking that is 00D00 but when I try :
SELECT REPLICATE(NCHAR(000D00), 5 COLLATE Latin1_General_100_BIN2)
It doesnt go thru, some one have any clue about how should I figure it out?
thanks
0x0D is a carriage return '\r', (char)13. Just use SUBSTRING(LastPriceChange, 0, 8) to get rid of it.
Could it be that you read the file as Unix format expecting only a '\n' (new line character, (char)10) as line separator instead of "\r\n" (carriage return + new line) as usual in Windows? This would explain why the 0x0D was left over.
See: ASCII, Control characters (Wikipedia).
I'm using a formula in Excel 2007 to grab a mailbox size from a string. I'm stripping out all of the text before and after, and removing the , characters, yet Excel will not format the result as a number.
Because of this, I can't run any statistics such as total size or average size.
=SUBSTITUTE(MID(MailboxEX01[[#This Row],[TotalItemSize]], FIND("(", MailboxEX01[[#This Row],[TotalItemSize]]) + 1, FIND("bytes", MailboxEX01[[#This Row],[TotalItemSize]]) - (FIND("(", MailboxEX01[[#This Row],[TotalItemSize]]) + 2)), ",", "")
I tried =TEXT({the above}, "#,##0"), which successfully added the , character as the thousands separator, but (I guess unsurprisingly) still failed to format the cell as a number.
Does anybody know how I can force the result in this cell to format as a number? Thanks.
Your formula takes text values, strips stuff out, and replaces stuff. But the result is still text. If the result of that formula contains only the characters 0 to 9, you can coerce it into a number by using
={your formula}+0
or
={your formula}*1
or
=--({your formula})
Using =TEXT({your formula}, "format") will not produce a number. The TEXT() function returns text, as the name implies.
But if you use a mathematical operator on a number that is stored as text (or a text that represents a number), the maths operation will coerce that text value into a real number. The third suggestion uses the double unary (Google that) to coerce the text into a number.
I have created a Fortran 90 code to filter and convert the text output of another program in a csv form. The file contains a table with columns of various types (character, real, integer). There is a column that generally contains decimal values (probability values). BUΤ, in some rows, where the value should be decimal "1.000", the value is actually integer "1".
I use "F5.3" specifier to read this column and I have the same format statement for every row of the table. So, when the code finds "1", it reads ".001", because it does not find a decimal point.
What ways could I use to correctly (and generally) read integers among other decimals?
Could I specify "unformatted" input only for a number of "spaces"?
The data edit descriptor fw.d for floating point format specification is for input normally used with zero d (it cannot be ommited). Nonzero d is used in the rare case when the floating point data is stored as scaled integers, or you do some unit conversion from the integer values.
You could try using list-directed input: use a * instead of a format specifier. This would be for the entire read, not selected items. Or you could read the lines into a string test their contents to decide how to read them. If the sub-string has a decimal point: read (string(M:N), '(F5.3)') value. If it doesn't, use a different format, e.g., perhaps read as as F5.0.
P.S. "unformatted" is reading binary data without conversion ... it is a direct copy of the data from the file to the data item. "listed-directed" is the Fortran term for reading & converting data without using a format specification.
well here's someting new to me: f90 allows a mix of comma and space delimiters for a simple list directed read:
read(unit,*)v1,v2,v3,v4
with input
1.222 2 , 3.14 , 4
yields
1.222000 2.000000 3.140000 4.000000
