Here’s how to use xlsimport() function.
Description:
Retrieve contents of an Excel file and return them as a table sequence.
Syntax:
f.xlsimport(Fi,…;s,b:e;p)
Note:
The function retrieves field Fi from row b to row e from Excel file f’s sheet s and returns them as a table sequence. Retrieve data from the first row to the last one when both parameter b and parameter e are absent.
Parameter:
f |
An Excel file. |
Fi |
To-be-retrieved fields; by default, all fields will be retrieved. The sign # is used to represent a field with a sequence number. |
s |
Sheet name or sheet number; use the first sheet when omitted. |
b |
The starting row; if omitted, retrieve rows from the first to row e; in this case, ":" can be omitted. |
e |
The ending row; if omitted, retrieve rows from row b to the last row; in this case, ":" cannot be omitted; if e is greater than the actual number of rows, use the actual number of rows. Retrieve rows backwards when e<0. |
p |
The password for accessing the Excel file. |
Option:
@t |
Export the first row in f as the field names; if not supplied, use _1, and _2,… as field names. When parameter b is supplied, it is treated as the header row. |
@c |
Return result as a cursor; support xlsx format only; in this case, parameter e should be greater than 0. |
@b |
Remove blank rows before and after the Excel data when reading them; will be ignored when @c option is present. |
@w |
Enable returning a sequence of sequences where members of sub-sequences are cell values; it cannot work with @t, @c and @b options. |
@p |
Work with @w to return a sequence of sequences; each sub-sequence is made up of column values. |
@s |
Enable returning a string delimited by CR/tab. |
@n |
Remove white spaces on both sides of a string; read an empty string as null. |
Return value:
Table sequence
Example:
Read the whole xls file:
|

|
2 |
=file("emp2.xlsx").xlsimport@t(;2,3:6) |
As @t option works, read the 3rd row as the title:
|
3 |

As parameter b is absent, read the first row as the title and retrieve rows of the data from the first to the sixth; “:” should not be omitted.
|
4 |
=file("emp2.xlsx").xlsimport(;"t2",7:) |
As parameter e is absent, read rows of data from the seventh to the last; “:” can be omitted.

|
A |
|
1 |
=file("emp3.xlsx").xlsimport@c() |
Return a cursor. |
2 |
=A1.fetch() |
|
Remove blank rows before or after the Excel content during reading:

1 |
=file("emp4.xls") |
|
2 |
=A1.xlsimport@b() |
@b option works to remove blank rows before or after the Excel content during reading and use the first record as titles.
|
Return a sequence of sequences:
|
A |
|
1 |
=file("emp1.xls").xlsimport@w() |
@w option works to return a sequence of sequences, where each row is a member of the sequence.
|
Retrun a sequence consisting of Excel columns:
|
A |
|
1 |
=file("emp1.xls").xlsimport@pw() |
@wp options work to return a sequence made up of Excel columns, where each column is a member of the sequence.
|
Return a string delimited by /tab:
|
A |
|
1 |
=file("emp1.xls").xlsimport@s() |
@s option works to return a string separated by CR/tab:
|
Remove white spaces at both ends of each string, and read empty strings as nulls:
|
A |
|
1 |
