I want to get the date values (day, month, year) from a date string that can be in any common date format (metric, retard, string, number, German, English...)
Some examples are:
"12. Mai 2022"
"5/12/22"
"May 12, 2022"
"05.05.22"
"12.5.2022"
Solutions can be Code (JS,PHP,Python), RegEx or (preferred) an API that does this. A 95% solution is fine.
Background: We are using the Google Document AI for scanning invoices, and want to put the date from the invoices into sheets, using a no code solution (Integromat / make.com). Unfortunately, the Document AI only returns the date field as a string, not as a date value.
If you're using certain Specialized Processors, like the Invoice Parser, then you should be able to use EKG Enrichment & Normalization to get the date in a standard string format, or as structured data.
You can access this in the normalizedValue field in the Document object. This How-to Guide Handling the Processing Response describes the process and the Specialized Processors Codelab has some code samples for how to do this.

I'm using flutter. In which way a DateTime should be stored in firestore so that I can make a filter based on the DateTime. Should it be converted to String or something else? What is the perfect way here?
Firestore has a native Timestamp type that can be used to store timestamps, which:
A Timestamp represents a point in time independent of any time zone or calendar, represented as seconds and fractions of seconds at nanosecond resolution in UTC Epoch time
This type is perfectly suited for filtering on date/time ranges, for example when you want to get all documents with a field between January 7, 2021 at 7:41:00AM and January 20, 2021 at 2:00:42PM.
In cases where I'm purely interested in a date and not in a time, I often store that as a string in "20210107" format (so yyyyMMdd). I find this format slightly easier when I want to get documents for a specific date, as I can use an equality filter. But the trade-off is that I love the precision of time. As you can probably guess from my phrasing this is a personal preference, not necessarily a best way for all cases or everyone.
It must be a string, you can split or format it as the day / month / year you want after the string value
I am using the Twilio log file to crunch some data and need to convert the Twilio format for dates into something that Google Sheets can recognize as a date so I can then extract what week of the month the date is referring to. Also would be helpful to get the syntax that converts the Twilio date to a recognizable date for Googlesheets in case there are other things I need to do with the date field.
Currently, this is the format in the log file: "2019-08-22 06:12:58 MDT"
I'm using this =text(index(split(I2," "),,1),"mmmm") to determine the month and am struggling to have this now be able to work with the WEEKNUM function of Googlesheets to get the number of the week the date is from. I've tried =DATE(index(split(I2," "),,1),"mmmm"), =WEEKNUM(index(split(I2," "),,1),"mmmm") but am terrible with the formula syntax and can't fix the date value.
=DATE(index(split(I2," "),,1),"mmmm")
I expect to see a value from 1-5.
The text() part of the formula is turning the date input into text. And so you can't use it to calculate the weeknum().
=weeknum(index(split(I2," "),,1)) will get you closer. But it will give you the week of the year.
You may want to see this for a way to get to week of the month from week in the year.
following 1 I started creating a Spreadsheet which reads data from BigQuery, but I'm having an issue handling parameters related to date values.
In the first sheet, I created 2 cells with 2 parameters, the start and the end of a date interval, with proper values. Both cells are formatted as "Date" value.
In the second sheet I configured BigQuery connector, for this example, I'm using a public dataset with dates. bigquery-public-data.utility_eu.date_greg
From the BigQuery connector wizard I added:
"STARTDATE" as "PARAMETERS!B1"
"ENDDATE" as "PARAMETERS!B2"
After this configuration, this is the resulting query:
SELECT
date,
date_str,
date_int
FROM `bigquery-public-data.utility_eu.date_greg`
WHERE date > DATE(#STARTDATE) AND date < DATE(#ENDDATE)
LIMIT 10
I'm getting an error directly from the editor with this message:
> Error BigQuery: No matching signature for function DATE for argument types: INT64. Supported signatures: DATE(TIMESTAMP, [STRING]); DATE(DATETIME); DATE(INT64, INT64, INT64) at [8:14]
As far as I can understand, the "date" cells are retrieved as a number, so the direct parse is not working. After a couple of tests, I understood the that given int value is the number I can obtain change cell format to "number".
If you convert cell value from DATE to NUMBER you get this value:
01/05/2019 -> 43.586
31/05/2019 -> 43.616
What is this number? It is not milliseconds, it increases by 1 every next day. In order to create the proper query that can parse this int, I need to understand what is this int (of course I can handle the cell as "text" and writing the timestamp value directly, but I would prefer to have the native date format so I can use the built-in calendar.
My consideration (with simple math) is that this number refers to a number of days since 30/12/1899, but it is very odd (also, every date BEFORE this days is always 0), so I'm asking you directly how to handle this value. Basing on my understanding of when the number counter starts (30/12/1899), I created this query which add the number retrieved from the cell:
SELECT *
FROM `bigquery-public-data.utility_eu.date_greg`
WHERE
date >= DATE_ADD(DATE("1899-12-30"), INTERVAL #DATAINIZIO DAY)
AND date <= DATE_ADD(DATE("1899-12-30"), INTERVAL #DATAFINE DAY)
It is working... but I think I'm doing a workaround that is not the proper way of doing this.
Also, is there any full documentation related to this BigQuery connection provided by Spreadsheet? Besides presentation in 1 I'm unable to find any specific documentation.
Spreadsheets (Google, Excel, ...) store the dates as days passed since a starting date with a fractional day representing time.
From here: "Excel stores dates and times as a number representing the number of days since 1900-Jan-0, plus a fractional portion of a 24 hour day: ddddd.tttttt . This is called a serial date, or serial date-time."
Now, you have to ways to filter by date on your Query:
In the query, you can use DATE_ADD to add your number of days (cell value) to the base date. (Carefull, DATE_ADD takes INT, and the date value is float so needs prior casting).
(preferred) on your spreadsheet you use TEXT(cell, "yyyy-mm-dd") so you can then use DATE() in the BigQuery query.
I use the second method as, though you need that extra cell (unless you directly store the date as YYYY-MM-DD; keeps the query cleaner than having a cast and date_add in there. Also would save you from the "1904 problem" explained in the link above.
What is this number? It is not milliseconds, it increases by 1 every next day.
This is so called serial number which represent number of days since "very beginning"
Google's Spreadsheet date calendar starts from 1900-01-01 - which is treated as a "very beginning"
In order to create the proper query that can parse this int, I need to understand what is this int
Armed with above info you can adjust you dates calculation to be in sync with what BigQuery expects
You mentioned that your fields are already in Date format, maybe you are doing an extra parsing in your query.
Try to do it without the DATE functions.
Also, I found this other doc, not merely related to connection, but might be helpful: Getting info from Spreadsheets with BigQuery.
I'm trying to calculate maturity date of a term loan using information from the application. I know the functions to brake down a given date mm/dd/yyyy into date, month and year. Is there a function to create the new date after i've changed these values.
for example - a 360 month term loan with first payment date on 1/17/2016 will expire on 12/17/2045.
Please help!
Thank you very much.
If your XSLT processor includes, or can load a version of, the EXSLT extension libraries, those can provide date manipulation functions (http://exslt.org/date/).
If you are using XSLT 2.0, date functions are included.
If neither of these is available, you get to implement it yourself, possibly by using custom extension functions that call Java date methods.
One of my customers would like to have a custom date column, where he could store the year only, a combination of month and year (without the day), or a classic date with day, month and year.
It should be possible to use this field for sorting the data. A "month-year" date should be considered as "01-month-year" for the sort, and a "year" date should be treated as "01-01-year" for the sort.
I could imagine two solutions to that:
Store the date in the standard "day-month-year" format, and keep in a separate column how the date was entered ("year", "month-year", "day-month-year"), so the approximate date can be displayed exactly how it was entered.
Use some sort of custom date column in the postgresql database.
Has anyone experience with that?
You could use date-time functions to extract date components. I don't think it has any sense to create additional columns. Also, some databases allow to create indexes by functions.
