问题
We imported a bunch of data into cells. But when you click on the cell, their is an apostrophe before the data, so it thinks its a string. By removing the apostrophe, the data gets recognized as dates. How do I avoid doing this by hand?
回答1:
Use a column beside the dates column.
Add a formula like this one:
=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2))
it will vary depending on your date format, copy this formula for all rows.
Then copy the results, and do a paste special where you paste values.
You now have a column with dates.
回答2:
Yep, go for Find Replace (Ctrl + H)
find: ' //apostrophe replace with: //leave this blank
click "replace all"
回答3:
I don't think the find and replce would would and the apostrophe is not part of the text, but a excel "feature". depending on how many you have to change - e.g. number of columns the simplist way I can think of without writing a macro would be.
Assuming your dates are in column A.
In a blank column put the following
=VALUE(A1)
This will store the date as a number. replicate the formulae down the column and then copy the values over the original dates. Apply cell formatting to short/long date if needed.
Hope this helps
