For those who may need a way to strip special characters from a string then here is a method using Microsoft Flow. You will create an array of special characters then iterate through your string data replacing any of the matching characters then outputting the sanitised string at the end. Whilst I am using a compose called "Compose Email Subject", this could be any string when you decide to incorporate this into your Flow.
The trigger I have used is a button, although this could just as well be any trigger.
Data transformation expressions in mapping data flow
Once the concept has been grasped here it is likely that this will be built into your own existing Flow. It just helps using a button to test so maybe start by building like for like in order to grasp the concept before incorporating into your own process.
Now a "Compose" called "Compose Email Subject". This is used for you to test your own email subject or string of your choosing so you can determine if the sanitation is complete in your case. Please change the value to suit. The above can be changed to suit. For example, if you only want to strip out a colon and a slash you could have. To follow best practice, create your own "Apply to each" and name it "Apply To Each InvalidCharacters", or a name of your choosing and within set 2 variables.
To finish off, outwith the looping control Apply to each add a compose called "Compose Sanitised Subject", as below. Any issues or questions, please reference this blog and post in Get Help with Microsoft Flow.
How Substring Works in Microsoft Flow
Adds a date to a number of days. Adds a duration to a timestamp. Appends one array of similar type to another. You can optionally pass a timezone. You can pass a optional stream name as the second argument. If there are multiple matches, the first match is returned. If no match it returns a NULL value.
Column names known at design time should be addressed just by their name. Computed inputs are not supported but you can use parameter substitutions. If the position is out of bounds it returns a NULL value. If the number of inputs are even, the other is defaulted to NULL for last condition. All inputs should be of the same type. The first parameter is the separator. Contains expects a reference to one element in the predicate function as item.
It can be used to calculate a fingerprint for a row. The local timezone is used as the default. Refer Java's SimpleDateFormat for available formats. It is defaulted to the current timezone. Use the function syntax false if there is a column named 'false'.
Filter expects a reference to one element in the predicate function as item. Returns null if all inputs are null. If other is unspecified it is considered NULL. Both the values must be compatible numeric, string It tests for all inputs until it finds the first non-null value. Words are identified as separated by whitespace. For transformations taking more than one input stream you can pass the 1-based index of the stream. The stream index should be either 1 or 2 and the default value is 1.
The escape character is ''. If an escape character precedes a special symbol or another escape character, the following character is matched literally. It is invalid to escape any other character. If the position is omitted it is considered from the beginning of the string. An optional base can be supplied else a euler number if used. If the string is equal to or greater than the length, then it is trimmed to the length.
If second parameter is unspecified, it trims whitespace. Else it trims any character specified in the second parameter.Concatenates individual strings of text and strings in tables. The Concatenate function concatenates a mix of individual strings and a single-column table of strings. The Concat function concatenates the result of a formula applied across all the records of a table, resulting in a single string.
Use this function to summarize the strings of a table, just as the Sum function does for numbers. Fields of the record currently being processed are available within the formula.
You simply reference them by name as you would any other value. You can also reference control properties and other values from throughout your app. For more details, see the examples below and working with record scope. Use the Split or MatchAll function to split a string into a table of substrings. To create these global variables in an app, insert a Button control, and set its OnSelect property to this formula:.
For these examples, set the Text property of a Label control to a formula from the first column of the next table.Microsoft Flow Trigger Conditions
For this example, add a blank, vertical Gallery control, set its Items property to the formula in the next table, and then add a label in the gallery template. For these examples, set the Text property of a label to a formula from the first column of the next table.
The last two examples include an extra ", " at the end of the result. The function appends a comma and a space to the Name value of every record in the table, including the last record.
In some cases, these extra characters don't matter. For example, a single-space separator doesn't appear if you show the result in a label. If you want to remove these extra characters, use the Left or Match function. If you used Concat with a separator, you can reverse the operation by combining the Split and MatchAll functions. For these examples, add a blank, vertical gallery, set its Items property to a formula in the next table, and then add a label in the gallery template.Have you ever wondered why the Expression box in Microsoft Flow is so small?
Often a one liner can do the job. Sometimes it is the small things in Microsoft Flow that make it difficult to get the job done! Most of these on liners will fit in that small expression box. For more details see my post about finding your run Url. Getting the first X characters is easy using the substring function. The following expression is your answer:.
When you set a variable to a space Flow will tell you that the value is empty. When you use switches in Flow and the switch value is sometimes not set you will find that your flow will fail. If you use the coalesce function you can make sure that you always get a value from a variable or action output. For more information see Improve your switches.
How often do you need to check the value of a text variable or output. A while back I was looking at the extensions of a file name.
To solve my problems I used the toUpper fuction:. The last expression spot in this post is still available. Have you used any great expressions? Please leave you useful one liners in the comments below. Please give expression to parse something from the string. Example to grep some word from body line of email.
It would very much depend on the kind of data you would want to extract and the format of the email. You could of course create an Azure function that does the work for you using regular expressions.
Then call this function from a flow. What ist the best way to handly long expressions?This page contains additional examples of all the String functions available in Microsoft Flow. This page will be updated periodically to include more examples created by the community.
Example 1 This example concatenates the value from 2 columns located in different SharePoint lists: concat triggerBody? Example 3 This example concatenates 2 variables of String type. The split function is discussed at the end of this post.
As for the sub function, this will be discussed in a future post about Math functions in Microsoft Flow. Example 1 In this example, the user wants to remove bullet points from a list of items contained in a column named Description: replace triggerBody?
See the expression below: Source: Example 2 Note: had to use an image to show the replace expression for example 2. Example 1 In this example, the user wants to convert the value from a choice column named EmployeeOnboardingType to lowercase.
See the expression below: toLower triggerBody? Example 1 In this example, the user wants to retrieve several keywords from the body of an email, including Start time. This retrieves the information before the space between the First Name and Last Name. Example 1 In this example, the user wants to retrieve the Account Number information from the body of an email.

When you create a flow, you can use the Condition card in basic mode to quickly compare a single value with another value. However, there're times when you need to compare multiple values.
For example, you may want to check the value of a few columns in a spreadsheet or database table. Sometimes your workflow needs to take an action if the value of an item is valueA or valueB. For example, you may be tracking the status of tasks in a spreadsheet table. Assume that the table has a column named Status and the possible values in the Status column are:.
Given the preceding spreadsheet, you want to use Power Automate to remove all rows with a Status column that's set to completed or unnecessary. Search for Scheduleand then select the Schedule - Recurrence trigger.
Use expressions in conditions to check multiple values
Note: Select the "get rows" action that corresponds to the spreadsheet that you're using. Select the folder icon in the File name box, browse to, and then select the spreadsheet that contains your data. Add the Value token to the Select an output from previous steps box. Add the following or expression.
This or expression checks the value of each row in the table a row is known as an item when accessed in a expression. If the value of the status column is completed or unnecessarythe or expression evaluates to "true". In the File name box, search for, and select the spreadsheet file that contains the data you want to delete.
The flow runs after you save it. If you created the spreadsheet shown earlier in this walkthrough, here's what the it looks like after the run completes:. Notice all data from rows that had "completed" or "unnecessary" in the Status column were deleted.
Assume you have a spreadsheet table with two columns. The column names are Status and Assigned. Assume also that you want to delete all rows if the Status column's value is "blocked" and the Assigned column's value is "John Wonder".In this article, I demonstrate how to showcase the names of people who have a birthday today. One thing that I really like about this approach is that the birth date is set in Delve and give each user the choice whether to share it with others or not.
If not, then their name will not appear on the SharePoint site. Other items that this solution can be extended to is to use the hire date and highlight specific anniversary milestones. To set your birthday, click the Update profile button when you first visit your profile page. This will take you to a page that looks like the one below. Each user can do this themselves.
What is important is that the icon on the right should show a globe to indicate that everyone can see the birthday. You can also use the employee's Hire Date to display work anniversaries.
To edit a user's hire date. As I decided to go with a no-code solution, I had to stick with one of the out of the box web parts that would provide a decent look. So, I actually chose an events list. I created a new list called Celebrationswhich is an out of the box Calendar list and linked it to the Events web part as shown on the right side of the page. The flow ensures that only users who have entered their birthdays and have a birthday on a specific day show up in the list that day.
I also uploaded an image called confetti. The Flow begins with a trigger being set to kick-off the flow each day at midnight. Make sure to set your time zone, otherwise you may have birthdays start and end time wrapping a calendar day.
Nothing fancy here. Just a loop that iterates through the Celebrations list and deletes all the items found. This is where the good stuff happens. The action starts by searching all Office users that match a given term by display name, given name, surname, mail, mail nickname or user principal name. Next, I use a comparison between today's date and a date that is available in the user's profile. As I've mentioned earlier, I have the user's birthday and hire date that I can set and to no surprise, the same fields are available as dynamic content from the Get user profile V2 action.
And finally, I add an item for each match into the Celebrations list.
Left, Mid, and Right functions in Power Apps
For the Start Time and End Time, I set them to go from midnight until just before midnight the next day. Remember the confetti. You can see it being referenced in the Banner URL field. This image appears at the top of each celebration event created.
With the modern Events web part, when there are no celebrations on a day, it shows the three default events, which is not ideal. As well, the Flow action does not allow to specify full-day events, requiring you to enter a start and end time. Maybe that would deserve a proper blog article I tried already to use this web part before but I found out that it was not ideal.
