||||||
|
|
||||||
|
### Generate a list of values
|
||||||
|
|
||||||
|
**Task:** New files are being dropped to a publicly accessible **Web page** which you have been tasked with collecting. All of the files maintain a consistent column - naming, data type - and the file names follow a format of **FactInternetSales_#.csv** to make combining the files easier.
|
||||||
|
|
||||||
|
1. From the **Home** tab select the drop-down for **Get data** and then **Blank query**.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
1. Within the **Advanced editor** window update the current query to the text below - creating a custom function that [combines text](https://docs.microsoft.com/powerquery-m/text-combine) and converts to [text from](https://docs.microsoft.com/powerquery-m/text-from) a value. Select **Ok** when complete.
|
||||||
|
|
||||||
|
```fsharp
|
||||||
|
let
|
||||||
|
// A function that accept a file number value and concatenates text
|
||||||
|
fxFileName = (#"File number" as number) as text =>
|
||||||
|
Text.Combine(
|
||||||
|
{
|
||||||
|
"FactInternetSales_",
|
||||||
|
Text.From(#"File number"),
|
||||||
|
".csv"
|
||||||
|
}
|
||||||
|
)
|
||||||
|
in
|
||||||
|
fxFileName
|
||||||
|
```
|
||||||
|
2. Open the **Advanced Editor** once again, add a comma to end of the **fXFileName** step and add a new step with the identifier name **Source** which equals a **Record** data type, containing the key values of **fileCount**, **fileName** and **data** and their corresponding values as displayed below and update the return value to **Source** after the text **in**.
|
||||||
|
|
||||||
|
```fsharp
|
||||||
|
let
|
||||||
|
// A function that accept a file number value and concatenates text
|
||||||
|
fxFileName = (#"File number" as number) as text =>
|
||||||
|
Text.Combine(
|
||||||
|
{
|
||||||
|
"FactInternetSales_",
|
||||||
|
Text.From(#"File number"),
|
||||||
|
".csv"
|
||||||
|
}
|
||||||
|
),
|
||||||
|
Source = [
|
||||||
|
fileCount = 1,
|
||||||
|
fileName = fxFileName(fileCount),
|
||||||
|
data = fxGetFile(fileName)
|
||||||
|
]
|
||||||
|
in
|
||||||
|
Source
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Enable the **Query script** view, to view the full script in the center of the window.
|
||||||
|
1. To validate the results are updating, change the **fileCount** value to **2** and review the data preview's **fileName** and **data** values.
|
||||||
|
1. Return the **fileCount** value to **1** before proceeding.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
5. Within the expanded **Query script** view, add a comma to the end of the **Source** step and add a new step with the identifier name **fileList** and value **List.Generate**, and update the return value to **fileList** after the text **in**.
|
||||||
|
|
||||||
|
```fsharp
|
||||||
|
let
|
||||||
|
// A function that accept a file number value and concatenates text
|
||||||
|
fxFileName = (#"File number" as number) as text =>
|
||||||
|
Text.Combine(
|
||||||
|
{
|
||||||
|
"FactInternetSales_",
|
||||||
|
Text.From(#"File number"),
|
||||||
|
".csv"
|
||||||
|
}
|
||||||
|
),
|
||||||
|
Source = [
|
||||||
|
fileCount = 1,
|
||||||
|
fileName = fxFileName(fileCount),
|
||||||
|
data = fxGetFile(fileName)
|
||||||
|
],
|
||||||
|
fileList = List.Generate
|
||||||
|
in
|
||||||
|
fileList
|
||||||
|
```
|
||||||
|
|
||||||
|
6. Update the script
|
||||||
|
|
||||||
|
```fsharp
|
||||||
|
let
|
||||||
|
// A function that accept a file number value and concatenates text
|
||||||
|
fxFileName = (#"File number" as number) as text =>
|
||||||
|
Text.Combine(
|
||||||
|
{
|
||||||
|
"FactInternetSales_",
|
||||||
|
Text.From(#"File number"),
|
||||||
|
".csv"
|
||||||
|
}
|
||||||
|
),
|
||||||
|
Source = [
|
||||||
|
fileCount = 1,
|
||||||
|
fileName = fxFileName(fileCount),
|
||||||
|
data = fxGetFile(fileName)
|
||||||
|
],
|
||||||
|
fileList =
|
||||||
|
List.Generate(
|
||||||
|
() => Source,
|
||||||
|
each not Table.IsEmpty([data]),
|
||||||
|
each
|
||||||
|
[
|
||||||
|
fileCount = [fileCount] + 1,
|
||||||
|
fileName = fxFileName(fileCount),
|
||||||
|
data = fxGetFile(fileName)
|
||||||
|
]
|
||||||
|
)
|
||||||
|
in
|
||||||
|
fileList

|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
### Generate a list of values
|
|
||||||
|
|
||||||
**Task:** New files are being dropped to a publicly accessible **Web page** which you have been tasked with collecting. All of the files maintain a consistent column - naming, data type - and the file names follow a format of **FactInternetSales_#.csv** to make combining the files easier.
|
|
||||||
|
|
||||||
1. From the **Home** tab select the drop-down for **Get data** and then **Blank query**.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
1. Within the **Advanced editor** window update the current query to the text below - creating a custom function that [combines text](https://docs.microsoft.com/powerquery-m/text-combine) and converts to [text from](https://docs.microsoft.com/powerquery-m/text-from) a value. Select **Ok** when complete.
|
|
||||||
|
|
||||||
```fsharp
|
|
||||||
let
|
|
||||||
// A function that accept a file number value and concatenates text
|
|
||||||
fxFileName = (#"File number" as number) as text =>
|
|
||||||
Text.Combine(
|
|
||||||
{
|
|
||||||
"FactInternetSales_",
|
|
||||||
Text.From(#"File number"),
|
|
||||||
".csv"
|
|
||||||
}
|
|
||||||
)
|
|
||||||
in
|
|
||||||
fxFileName
|
|
||||||
```
|
|
||||||
2. Open the **Advanced Editor** once again, add a comma to end of the **fXFileName** step and add a new step with the identifier name **Source** which equals a **Record** data type, containing the key values of **fileCount**, **fileName** and **data** and their corresponding values as displayed below and update the return value to **Source** after the text **in**.
|
|
||||||
|
|
||||||
```fsharp
|
|
||||||
let
|
|
||||||
// A function that accept a file number value and concatenates text
|
|
||||||
fxFileName = (#"File number" as number) as text =>
|
|
||||||
Text.Combine(
|
|
||||||
{
|
|
||||||
"FactInternetSales_",
|
|
||||||
Text.From(#"File number"),
|
|
||||||
".csv"
|
|
||||||
}
|
|
||||||
),
|
|
||||||
Source = [
|
|
||||||
fileCount = 1,
|
|
||||||
fileName = fxFileName(fileCount),
|
|
||||||
data = fxGetFile(fileName)
|
|
||||||
]
|
|
||||||
in
|
|
||||||
Source
|
|
||||||
```
|
|
||||||
|
|
||||||
4. Enable the **Query script** view, to view the full script in the center of the window.
|
|
||||||
1. To validate the results are updating, change the **fileCount** value to **2** and review the data preview's **fileName** and **data** values.
|
|
||||||
1. Return the **fileCount** value to **1** before proceeding.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
5. Within the expanded **Query script** view, add a comma to the end of the **Source** step and add a new step with the identifier name **fileList** and value **List.Generate**, and update the return value to **fileList** after the text **in**.
|
|
||||||
|
|
||||||
```fsharp
|
|
||||||
let
|
|
||||||
// A function that accept a file number value and concatenates text
|
|
||||||
fxFileName = (#"File number" as number) as text =>
|
|
||||||
Text.Combine(
|
|
||||||
{
|
|
||||||
"FactInternetSales_",
|
|
||||||
Text.From(#"File number"),
|
|
||||||
".csv"
|
|
||||||
}
|
|
||||||
),
|
|
||||||
Source = [
|
|
||||||
fileCount = 1,
|
|
||||||
fileName = fxFileName(fileCount),
|
|
||||||
data = fxGetFile(fileName)
|
|
||||||
],
|
|
||||||
fileList = List.Generate
|
|
||||||
in
|
|
||||||
fileList
|
|
||||||
```
|
|
||||||
|
|
||||||
6. Update the script
|
|
||||||
|
|
||||||
```fsharp
|
|
||||||
let
|
|
||||||
// A function that accept a file number value and concatenates text
|
|
||||||
fxFileName = (#"File number" as number) as text =>
|
|
||||||
Text.Combine(
|
|
||||||
{
|
|
||||||
"FactInternetSales_",
|
|
||||||
Text.From(#"File number"),
|
|
||||||
".csv"
|
|
||||||
}
|
|
||||||
),
|
|
||||||
Source = [
|
|
||||||
fileCount = 1,
|
|
||||||
fileName = fxFileName(fileCount),
|
|
||||||
data = fxGetFile(fileName)
|
|
||||||
],
|
|
||||||
fileList =
|
|
||||||
List.Generate(
|
|
||||||
() => Source,
|
|
||||||
each not Table.IsEmpty([data]),
|
|
||||||
each
|
|
||||||
[
|
|
||||||
fileCount = [fileCount] + 1,
|
|
||||||
fileName = fxFileName(fileCount),
|
|
||||||
data = fxGetFile(fileName)
|
|
||||||
]
|
|
||||||
)
|
|
||||||
in
|
|
||||||
fileList
|
|
||||||
```
