Hello, I made a a replace text block (okay, actually its 25 blocks size) ![Screenshot from 2018-02-08 06-39-12](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/2X/1/197f9bf2cd40c9639ccf8047de470ba10e3e124f.png) If anybody has a better suggestion, let me know! šŸ˜ƒ cheers, User81 ---

Can you just use a space as the delimiter?? ---

I can replace every character or string I wantā€¦ I just put the string into the variable ā€œreplaceStringā€ and right after that I start the function ā€œdo somethingā€ with the result ā€œreplaceStringā€ (for example: label.text=ā€œdo somethingā€) ![Screenshot from 2018-02-08 13-16-18](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/2X/c/c13313b20afa068bd1915c7c62884bc18faa5812.png) ---

actually its a lot easier. just build your own replace string/character or remove string/character function. Thx to the thunkable developers for making the functions so reliable in the recent update!!! ![Screenshot from 2018-04-09 21-43-26](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/9/c9a46f32a36ed5ecd7e58210fa2705e9c389ac04.png) ---

This is really neat. If you donā€™t mind my asking, whatā€™s the use case? Iā€™m interested in how youā€™re applying this, or what your app does (helps me get ideas on how to improve my own work). ---

Hi ervarela, thank you for your interest. My app is all about sharing text and pictures to each other - and therefore uses the realtime database (firebase) . firebase does not like a few characters, so I want to make sure to remove or replace these viciuos characters before sending a textstring to the firebase. another usecase would be to replace characters to make a URL code. (thunkable android has these blocks by default, so I did not really invent them šŸ˜†) ---

Iā€™m wondering what is powering the function.

Hi User81 Found this quite useful but i have a slightly different use case. I want to replace a character at an index with another character. so the delimiter is actually an index, not a character. Any ideas? Thanks Ravi ---

Hi there, We have made some updates since this post was first made in 2018 - we now have a [replace text](https://docs.thunkable.com/text#replace-all) block! You can replace a given character (or characters) in the following way (Imagine Iā€™m replacing the characters between #x and #y): [get substring from #1 to #[x-1]](https://docs.thunkable.com/text#get-substring) insert my new [string](https://docs.thunkable.com/text#string) [get substring from #[y+1] to last character](https://docs.thunkable.com/text#get-substring) [join](https://docs.thunkable.com/text#join) these together ---

Was just searching for this now. Itā€™s a cool solution. It will be useful if you can wrap it as a new function to replace substrings between given indices. ---
